PLEASE READ BEFORE COMMENTING OR USING AN SLA PRINTER! In my latest video on air-quality and 3d printing there was a post by a medical doctor which I am reposting here for reference you can see the original here ( ruclips.net/video/vc-0yeWowYk/видео.html ) : "Joe sorry I have been out of pocket for a few episodes and I noticed this episode. Unlike you, I am a doctor and have spent almost 4 decades slicing and dicing the human body. The MSDS sheets that are required by every company that sells to another company that has employees are irrevalent for consumer activity The assumptions are that in a business or industrial use the ventilation will be much different, the typical building construction is much different, and most importantly the user will typically be isolated from the direct effect of the outgas as opposed to having a 3D printer in the den or in some cases the dorm room where you sleep I am not as concerned about PLA as I am ABS. NO doubt that ABS is a non-consumer based product in terms of manufacturing uses. It IS one of the most used plastic in the world but that is post-processed. Sure it can be used as many do no different then anyone can change their own brakes but realizing that brake pads/shoes are made up of asbestos which we are 100% sure is a carcinogen. Mechanics know the risks and mitigate at every opportunity. The REAL bad boy is still to be gone over. The SLA resins are the bigger issue Just in the past 12 months, we have had two bouts of ED visits leading to admission. Inhaling that stuff is SUPER nasty. The one episode was a girl and her dad and the other was a mature college student (mature in age not so in intelligence) The two totally independent episodes claimed they followed the directions completely the college kid used his resin printer in his dorm room with no special care or vents or even taking it into the common space. It overtook his lung capacity and he passed out. Post-exposure he lost all memory and to my knowledge has never gotten it back (a VERY serious situation showing how much brain damage was caused in a short time) The two family members who were just learning resin printing followed the instructions and actually brought the resin into the ED so we could analyze it. The father was in the ICU for a few days and then needed to see a pulmonologist for lung care follow up This stuff is NO toy; as we push the limits of temperature in order to get better prints we also push the gases out of the material and that causes the issues. Also, many of these compounds that might be imperceptible on meters like Joe is using after a week or 4 of printing have built up to serious levels More and more homes are actually sealed better than any other building we encounter for the sake of energy savings Sick House Syndrome is a real issue. Homes and dorms and apartments are not like HD/Lowes with constantly opening doors and ceilings set at 22' for storage purposes. The sealed up house or dorm might take a few 3D prints to build up formaldehydes or dioxides or sulphur gases sufficient to measure but by then your lungs are screaming for help Bottom-line don't for ONE second think that 3D printer filament is all safe and that they are all similar. The cheap Asian stuff has had tiny ball bearings inside as well as foreign compounds that were unable to be determined by basic techniques. Add some heat to that and see what gasses out. Surely I would never print without sufficient ventilation and if you insist on building an ABS enclosure you MUST vent it before going inside to recover the print. I suggest a long section of shopvac type hose connected to a Shop Vac unit exhausted outside with another section of hose OR put the whole printer in the garage or on an open deck if the weather allows Looking back a long time ago I can remember working on antique and muscle cars and grabbing the good old air hose with the trigger adapter on it and blasting the entire wheel well area and the brake areas and the inner wheel spaces. Now no one stupid enough to have done it is around to discuss it What we all assume is fine today might be found to be no so fine in 10 or 20 years just be careful and use your head. if you can use Fusion 360 you have the intellect to know about ventilation and distance vs concentration curves. Dr Dave"
Way too much drama and stressing your point over and over again. I get it, it's bad stuff. Now my question is you talk about ventilation. If you have a good enclosed ventilation system you should not be smelling any fumes. So a better video would be about what you did to fix the problem of breathing the toxic fumes and what kind of gloves you wear when handling the parts. I have a enclosure made out of PVC pipe for the frame with foil cover insulation foam board aluminum taped to the PVC pipe. Its power vented using a inexpensive radon vent fan and I use a 3 inch gate valve to control the air flow. Yes it blows outside. Super inexpensive setup and super safe. I lite up the box with LED under cabinet lights and I have a smoke detector mounted near the air exhaust just in-case.
If you like respitory injury sure no drama as this stuff is VERY BAD, one of my viewers a Medical Doctor wrote me about this (you can see the post here: diy3dtech.com/dr-daves-post-on-resin-based-printers/ ) after making becuase just in his hospitial they have seen so many cases related resin printers . As yes you can vent it and they do make vent hoods for this (this is how these are handled in commercial settings) as you too have have to deal with the cleanup of the parts and this stuff gets all over (so your also just flush this down sewer for your local municipality to deal with or worse yet into a septic and contaminate groundwater? See here is the point, yes you can do a lot of things in your home, however is that the right thing to do? So the fumes evacuating from your home, what about your neighbors? As I can build a Farnsworth Fusor in my basement and expose my family and neighbors to high level of neutron radiation too, is that right just because I can do it?
Not to diminish your warning... But I open my first bottle of UV resin and within minutes the entire house smelled an awful chemical poisonous smell. I had the family go outside and I ventilated the house. Then I asked on a forum. No one else had experienced that even with the same brand. So I opened another bottle and there was very little smell. After digging up information I found that the UV resins usually have low VOCs and the risk is with skin contact and not inhalation. I can't explain what happened to that defective bottle, but I felt safe getting rid of it and using the others with moderate ventilation.
Thanks for sharing, actraly had two bottles of differing brands and had a reaction to both. I wouldn't say the smell it self was over whelming it was more so the reaction to it and after reading the MSDS wasn't worth it me...
Made in china... They do not care about health, they pollute, destroy the environment, there are thousands of Chinese products that do not meet any safety requirement and enter all countries without having controls, well-known brand water bottles that do not comply with anything and contaminate food , the same kitchen utensils and pots, plastics that have toxicity, asbestos in materials that should not have them, they are an industry of terror but they disguise it as something normalized.
DLP not SLA, huge difference. You may have a bad batch or resin, if the smell is that intense something is wrong. I find it hard to believe that you did not account for fumes before you bought the printer or even research the possibility of them
I understand the difference and it moot as both are resin based and no on the bad batch concept (I tried several brands). The point is this stuff is not intended for in home use (you can read the SDS sheet if you want to disagree as they are very clear they contain bad things and the links are in the description). Also this is why I did this video as do "you" take into account every aspect of everything? It simply isn't possible as when you make a purchase such as this your expectation is there is relative level of safety. Also it's less about the how noxxious the fumes are, but more so how "toxic" (again read the SDS) they are...
And this is also why you wear gloves and air well when working with epoxy, the amine hardener is same thing, just a lot less active. It's possible to become allergic to it over time.
I'm guessing you did a lot of research on SLA printers in general before purchasing this one... given just how many warnings there are out there about materials like UV-activated resin, I am just amazed that you didn't anticipate this as being a problem or something you should look out for. You could have seriously injured yourself or a pet or another person. Sorry to seem harsh, and I'm glad you put the video out... but... I honestly am just surprised.
In addition, you're using things like Laser Cutters - -how about the off-gassing from the materials you cut there? If you've already got a ventilation system that can handle things like aluminum laser cut off-gassing, I would think you could utilize it very easily to do SLA Printing.
Actually not and the reason I made this video when I did because this video is getting rather old now and no there was very little out there on SLA printers at that time. Also this is being sold to Joe consumer which has no idea about MSDS sheets and the like and assume that since it is being sold its safe (a common misconceptions Americans have). In fact this is supported by this post (diy3dtech.com/dr-daves-post-on-resin-based-printers/) from a doctor from just one hospital and the cases he has seen. Now to your question about lasers, a far different animal as yes there are fumes but also depending on the material may or maynot be nastier, yet if you have followed my videos you see I am big on fume extraction and this is key. Now what folks like yourself miss is there are people who are unknowing buying this for their kids and as in the post there are bad things happening as yes trained people handle poisonous snakes all day but that does not mean that is suitable for the public. The other difference in laser verses SLA is the fumes are confined in the laser however this SLA resin get all over as its a messy process so yes I could have installed it in a fume hood as I have done with my ABS printers (as that too is nasty) yet again as you wash the SLA and cure, you cannot but help get the stuff all over so a major difference. Its worth keeping in mind a residential home is NOT a factory and they are designed and situated that way for reason as even with fume evacuation your making your problem your neighbors problem and is that right? Just think do you want your neighbors giving your kids cancer?
Only a totally careless person would buy a device like this for their kids without doing the research first. Only a totally careless person would run this machine or handle UV resin in a shared environment. I saw the post by the doctor and I TOTALLY AGREE. This is what I don't understand: you are basically the person that made these mistakes. Yet, you still don't know whether or not off-gassing from lasers "may or may not be nastier". This is what is so confusing... figure it out, especially if you have children, pets, or other living things around. JUST THINK: do you want your neighbors giving your kids cancer?
LOL! "Only a totally careless person would buy a device like this for their kids without doing the research first"! Happens all day long! Most of what I do with the laser is engraving so very little outgassing as well as any cutting is either wood or cast actrylic and I live in a bit of rural setting as not to give the neighbors cancer. Yet I have people write me all of the time about using lasers in apartment building! That is wacked! Yet the key here is it's easy to evacuate a laser and not so easy for SLA as you can do every thing under a fume hood in your home and second it gets all over...
As some other fellows say, you might have a defective sample. I have been using the orange sample Wanhao sent me with their printer, and even the smell is strong, I have had no problem with it. I have started using FTD resins, and the smell is less intense than the sample. That being said, I agree with other fellows and encourage everyone to wear respirator, safety goggles and gloves when handling resins. When things are done properly, the experience is way far from being a life threatening one. Also, I don't think a resin print runs longer than a FDM one: while an FDM head has to run through all the paths to print a model, the D7 projects the whole section of the geometry from the LCD to the resin. Plus you do not need infill.
Tried two different brands and for clarity it not so much the "smell" but the "fumes". Now a very important point here is what the MSDS sheets say is "bad" so even if you don't smell anything there still are "fumes" which are bad and you are are exposing your self to bad stuff. Again not preaching, but people people seem to confuse smell and toxicity, however Carbon Monoxide has no smell but will kill you. So please be safe my friend :-)
Different people have different levels of sensitivity to a particular chemical. An example is peanuts: most people get nutrition from eating them, however a few go into anaphylactic shock and can die. Figure out which you are for these resins. One problem to avoid is getting more sensitive when your body is exposed to something too much. E.g. think about having sore feet. Stop walking, you feel better tomorrow. Keep walking on them and develop bloody blisters. Use good ventilation, and be sure about where the exhaust fan is sending the fumes. E.g. some bathroom exhaust fans aren't hooked up to a roof vent and just blow into the attic.
Good video Lot of people attacking you for not doing research which is sort of fair I am glad you've raised this point as I'm looking to buy this and was not previously aware of this so your video has served it's purpose Thanks
Thanks yet if you read down the thread have done my home work and even supported by a medical doctor: diy3dtech.com/dr-daves-post-on-resin-based-printers/
I just put an order on this printer, I plan to keep it in a well ventilated space in my basement, and I only ever handle resin when wearing a mask, glasses, latex gloves, until everything is cleaned up and the print is fully cleared
Since it is inside the air envelope of your home (i.e. basement) I would still suggest a negative pressure ventilation system as this stuff is nasty and while your protected for the moment, the chemicals will linger and settle in your home no good for other family members or pets...
Thanks, however the first myth to dispel is "no order" means nothing as it is not the smell which will harm you. Also, you need to read the MSDS (www.edv-3d-druck.de/media/pdf/2b/53/f1/MSDS-HARZ-Labs-Basic.pdf) not nice stuff, keep in mind the cured product is not the issue, its when its in a resin state. Like Asbestos, the solid version is safe however its when it breaks a part it becomes an issue. As it clearly notes: P261: Avoid breathing dust/fume/gas/mist/vapours/ substances in an atomized state. As it also it also states it should be used with local ventilation (i.e. fume hood)...
So you are you telling me everyone knows what an MSDS sheet? And everyone thinks about that? Also its more then just a "smell", as it appears you did not listen to nor read the inserts to the video? This is a health hazard, so what do I have to say about your "dramatic" comment? Buy one and breath deeply my freind:-)
I really liked the review, these things are not a joke to play around with. Long time exposure to different resins could lead to allergic reactions, this is the case with 2 component glues too, so be aware my friend! The other thing is that these chemicals might build up in your system, it is always a good idea to play it on the safe side, a proper gas mask and and a chemical protective suite is not expensive, not even by Eastern standards. Play it safe, and have fun, guys! :)
This video is ridiculously long to say about 30 seconds worth of material. You don't get to the point until 2:28. Alternative script: "Hi, I bought this, I didn't understand how strongly SOME people are sensitive to the materials, I was sensitive to the materials. I suggest you buy JUST some resin, open the jar, and if you feel an abnormal sensitivity, don't buy the printer. Thanks, bye."
Too bad you couldn't figure out a way to work this into your lifestyle. These are great little printers. I have the Photon and it has been a revelation. FDM almost seems archaic now. You're missing out. :-(
Its not really a fact of "working" it into ones life style as plain out the chemicals are dangerous and intended for for home settings. This article from a medical doctor share ER incidents from only his own hospital is worth a read: diy3dtech.com/dr-daves-post-on-resin-based-printers/
Good point on the hazardous nature of the resin but I might add that any resins are hazardous and to think that a machine that requires a resin would be anything other than hazardous is naive. Even super glues should be handled with gloves, respirator and goggles. If you want high quality prints then use in a well ventilated area with the right PPE. You should be doing that with ABS prints anyway, the off-gases from that are also hazardous. Im sure theres a whole plethora of chemicals in your workshop that are just as hazardous, just take the proper precautions.
In a way I was naive in thinking there would be "controls" but I should have known better (this should not be sold into a non commercial setting as people are going to be dumping this into the sanitary sewer, etc), however I am not sure I agree with you totally as there is a level of toxicity based upon volume as there is ton of stuff which is poisonous we come into connect every day with in low volumes like super glue. Also if you noted in the video I discussed the fact I do have a ventilation in the shop (mainly fro ABS and HIPS) and it could not deal with the fumes from this. As I expected out gassing, but not to the level which I experienced...
DIY3DTECH.com Repeated exposure to these types of chemicals are known to cause an escalating allergic reaction. This is important for people who are new to the trade to understand as it not only impacts the individual working with it, but also anyone in the nearby vicinity.
You are totaly right. Your video should be long as 20 sec. You repeated the same info over and over, picking up and putting down thw bottle for dozens of times. Thanks for your output.
Interested in your opinion of the new Prusa resins. They seem to be much safer than this cocktail from China. The Prusa MSDS says that the fumes are safe to breathe so long as no misting conditions are present.
I would be highly surprised if this is the case as keep mind that MSDS typical refer to the "solid" state of the product and all resins work basically the same, do you have a link...
There are some safe resins, monomer free resins are supposedly non toxic. They are more expensive but worth the extra cost especially if your chemically sensitive. Also, some resins are much more toxic than others.
If you have a link to a "non-toxic" resin can you share it? While I have not looked in the past couple months, all the resins I did look at were all pretty much the same and because of this were intresiticaly toxic. However would love to see the MSDS sheets for a non-toxic version as that would be great even if more money :-)
Thanks for the warning, I'm thinking of getting an sla printer but have particular sensitivity to allergens and chemicals so this will be important to test out before I take the plunge. Better safe and informed than ignorant and sorry.
I've been reading a lot of reviews about this stuff and wondered about the safety of the resin. I was reading about the Monocure resin, which The Hot End suggested as being better than the included resin. Upon checking their website and downloading the SDS tab, the PDF says a lot of the same things you found ("Causes skin irritation", "May cause respiratory irritation" and so on). This disappoints me since I have seasonal allergies galore and mild asthma. I have a well ventilated shop in the basement of my home, but since these prints run so much longer than FDM, I am debating the risk.
That is the same as I found that they are all basically the same and my wife too has mild asthma and I just couldn't expect her exposed to that if it caused me issues. As yes when I ordered mine also bought a liter of the Monocure resin too and it was no different sorry to say as simply think about it, they all basically work the same so how different can they be? :-(
So I tied an onion to my belt, which was the style at the time. Now, to take the ferry cost a nickel, and in those days, nickels had pictures of bumblebees on 'em. Give me five bees for a quarter, you'd say. Ah, there's an interesting story behind that nickel. In 1957, I remember it was, I got up in the morning and made myself a piece of toast. I set the toaster to three: medium brown.Now where were we? Oh yeah: the important thing was I had an onion on my belt, which was the style at the time. They didn't have white onions because of the war. The only thing you could get was those big yellow ones...
I've tried many different Acrylate based 3D printer resins and while they are all nasty, the Wanhao resin is particularly horrid. It caused my eyes to burn when just getting near the printer when using it. The bottom line is that any resin printer should be used in a very open area such as a garage with the door open, or else under a fume hood or box with exhaust fan. Acrylate resins are a serious health hazard because after you are around them for awhile you get numbed to the smell and don't notice it as much. But the toxic vapors are accumulating in your bloodstream will eventually cause neurological damage if you continue to expose yourself to them.
You are 100% correct, that is what what people don't realize about these printers and even using in fume hood, the resin tends to get on everything as it is a very messy process...
So you are allergic to that resin... yes, there are others out there with varying levels of outgassing... many of the other chemicals you are likely using in your shop have MSDS sheets that are worse or equivalent to the resin... While I concur that effective ventilation and protective gear are much preferred, also note that the outgassing of that ABS is also equivalent (and can equal some resins)... any time you are working with chemicals or "burning" (like with that Laser cutter) you are exposing yourself to those VOC's... You may wish to check on some of those MSDS for your other chemicals and equipment and/or increase the active ventilation... Also, burning wood is far *more* toxic in many ways, as is the rosin core of that roll of solder I see... Good for applying caution and (finally) researching all the facets of an activity... loss of a few points in making it sound a bit more "horrific" than it really is. Your sensitivity is higher than a lot of others. That is part of the reason that the verbiage said "May" on the MSDS...
Thanks for commenting as no my sensitivity is higher than a lot of others and yes looked at them all and while slightly different they all need work the same and are far worse than ABS ever thought of being. In fact on my latest video on air-quality a (medical) doctor posted what will follow and it is clear people are being immediately harmed by SLA resin as this was not intended for "home" use but as an industrial chemical in an industrial setting. So here is the quote and print safe my friend: "The REAL bad boy is still to be gone over. The SLA resins are the bigger issue Just in the past 12 months, we have had two bouts of ED visits leading to admission. Inhaling that stuff is SUPER nasty. The one episode was a girl and her dad and the other was a mature college student (mature in age not so in intelligence) The two totally independent episodes claimed they followed the directions completely the college kid used his resin printer in his dorm room with no special care or vents or even taking it into the common space.

Also, many of these compounds that might be imperceptible on meters like Joe is using after a week or 4 of printing have built up to serious levels"
I am not going to deny that some things can be dangerous if handled poorly... I can easily point to the old plastic model glue that some started to "concentrate and inhale in order to get "high"... Not it's intended use or a safe way to handle it and obviously proper ventilation was completely ignored... and yet millions of people understood the "risks" and handled it properly with no issues.... No, 3D printing is not a Star Trek Replicator... it is an industrial tool that has been modified (and price reduced) to be within the reach of an average user. That being said, one should learn about the tool, any hazards involved, and how to mitigate or eliminate those hazards. Just like other household and even shop appliances/tools, there are things you do to safely operate them (Don't stick Tupperware in an oven, don't stick a knife in a toaster, don't use any corded item in the shower) there are also people who don't observe or ignore those warnings (for whatever reason) who will continue to populate the ER of hospitals in response to their actions. I am not trying to cownplay either of those instances, it is quite likely to be seen in other places and by other doctors... The point is to respect the needs and requirements of the tools we choose to use, and observe reasonable safety precautions.... or don't use them!
Really... Names and citations or it's just hearsay... Two, only two... and the so called symptoms... fascinating way he describes them... I'm also laughing about this "doctor" description of "pushing temperatures higher to get better prints" this prints at room temperature, there isn't even a heater involved... he appears to be mixing different technologies... then there is the "Week or four of printing" where those compounds have built to serious levels... maybe in a closed room where no one ever enters or leaves so there is no air exchange or ventilation... then again, if you stayed in a small room with no air exchange just breathing, the CO2 content from your own breathing will knock you out long before the first week... Your "doctor" makes a bunch of very interesting claims but then does nothing to back them up... he goes on to make some rather dubious (if not outrageous) claims later on.. "Tiny ball bearings in cheap Asian stuff" seriously? As I stated before and will reiterate here... Bottom line, these are tools and chemicals... just like any other tool or chemical compound, there are certain safety precautions that you take to handle them... Use them according to instructions and all is good, ignore them and bad things can happen... for instance, try mixing typical household bleach and ammonia... hope you like toxic chlorine gas... but they sit under the kitchen sink just fine and behave themselves if you follow directions and don't mix them... Safety is being aware of your surroundings, understanding consequences of actions, and taking appropriate precautions... if you choose to ignore these you will self select out of the gene pool... fear mongering is useless, education, understanding, and proper precautions works wonders...
You are pre sensitised to the resin. You obviously have exposed yourself to epoxy resins in the past. You should never let any epoxy get on your skin, you should always wear gloves. Now if you hadn't repeatedly exposed yourself to epoxy resins in the past and pre sensitized your system. You would not of had a bad reaction or in fact any to the resin. That's the problem with SLA you start good and then as you expose yourself bit by bit to the resin your system gets more and more sensitive to the resin till it becomes impossible for you to work with it. So to all you people who like to use your fingers to apply epoxy or not wear gloves you are setting yourself up to get really sick if you try to use an SLA printer. Me I can't go near the stuff been playing with all types of epoxy resins for fifty years and my system will react badly. So if you don't react now, keep it that way by wearing gloves and respirator and you will not have a problem.
Thanks for commenting as the issue is if this is a possibility due to sensitivity, this is bad [as in hazardous] stuff. Take cigarette smoke, one can get use to it, yet it will kill you slowly and the SDS is clear. Resin is nasty stuff and yes while wearing gloves and respirator may help me, issue becauses what about my family member and pets? Because of HIPPA they can't publizie the data, however though friends in the respiratory community i have learned of 4 serious inhalation cases resulting in serious lung damage.
DIY3DTECH.com I agree, my main point was people use common chemicals and don't take proper precautions because of it's just epoxy, it's just solvents. The chemicals won't necessarily kill you now but they will effect you down the line. How many people watching have a FDM printer in their bedroom. PLA it's safe, but the particles are not good to breath in a enclosed space.
Holy heavens ... I do not want to die of cancer or something because I'm playing recreate my toy models at home ... is it really poisonous or chemically dangerous?
the monocure resin i am using smells weird and i was asked to move it out of the house as the missus started to feel nauseous and got a headache-it was only in the house 2 days. I had no issue and I was closer to it and got it on my hands quite a few times, which I washed off immediately.
Different people react in different ways, however even if doesn't "bother" you at the moment. It is still important to read and understand the MSDS sheet as it is some nasty stuff...
yes agreed- i have chemical handling experience and it is all now in the shed with good ventilation and all the rags and wash pots and stuff get stored in a containment box and prints are also handled as "dangerous until post curing has stopped the strong smells coming off"-I dont know if you have come across the story of the girl who was using 3d printed containers to grow her experimental zebra fish in-----fish eggs all died and they found that post process curing reduced egg death.
No but not surprised and would still be concerned it only reduced and didn't eliminate the fatality rate. Just be safe my friend I need all the viewers I can get :-)
Made in China .They do not care about health, they pollute, destroy the environment, there are thousands of Chinese products that do not meet any safety requirement and enter all countries without having controls, well-known brand water bottles that do not comply with anything and contaminate food , the same kitchen utensils and pots, plastics that have toxicity, asbestos in materials that should not have them, they are an industry of terror but they disguise it as something normalized.
LOL! Your smoking the dope! Can tell your NOT a medical doctor! Read what a real medical doctor has to say! diy3dtech.com/dr-daves-post-on-resin-based-printers/
Sort of, yet assume you also saw the saw 3D Printing Air Quality playlist (ruclips.net/p/PLInTrkIbj69kz2Uf_c3JIIzgwvDdUEsPO&disable_polymer=true) where I only print ABS & HIPS with external ventaltion as well as the test which I performed on ABS. Also, while ABS is not nice, there is no comparison between the dangers of ABS and resins to be very clear. Also I will re-post below a comment from a medical doctor who on the ABS/HIPS thread shared the patients he has come into just his hospital that were overcome by resin (You can read the complete thread here: ruclips.net/video/vc-0yeWowYk/видео.html&list=PLInTrkIbj69kz2Uf_c3JIIzgwvDdUEsPO&index=2 ): Joe sorry I have been out of pocket for a few episodes and I noticed this episode. Unlike you, I am a doctor and have spent almost 4 decades slicing and dicing the human body. The MSDS sheets that are required by every company that sells to another company that has employees are irrevalent for consumer activity The assumptions are that in a business or industrial use the ventilation will be much different, the typical building construction is much different, and most importantly the user will typically be isolated from the direct effect of the outgas as opposed to having a 3D printer in the den or in some cases the dorm room where you sleep I am not as concerned about PLA as I am ABS. NO doubt that ABS is a non-consumer based product in terms of manufacturing uses. It IS one of the most used plastic in the world but that is post-processed. Sure it can be used as many do no different then anyone can change their own brakes but realizing that brake pads/shoes are made up of asbestos which we are 100% sure is a carcinogen. Mechanics know the risks and mitigate at every opportunity. The REAL bad boy is still to be gone over. The SLA resins are the bigger issue Just in the past 12 months, we have had two bouts of ED visits leading to admission. Inhaling that stuff is SUPER nasty. The one episode was a girl and her dad and the other was a mature college student (mature in age not so in intelligence) The two totally independent episodes claimed they followed the directions completely the college kid used his resin printer in his dorm room with no special care or vents or even taking it into the common space. It overtook his lung capacity and he passed out. Post-exposure he lost all memory and to my knowledge has never gotten it back (a VERY serious situation showing how much brain damage was caused in a short time) The two family members who were just learning resin printing followed the instructions and actually brought the resin into the ED so we could analyze it. The father was in the ICU for a few days and then needed to see a pulmonologist for lung care follow up This stuff is NO toy; as we push the limits of temperature in order to get better prints we also push the gases out of the material and that causes the issues. Also, many of these compounds that might be imperceptible on meters like Joe is using after a week or 4 of printing have built up to serious levels More and more homes are actually sealed better than any other building we encounter for the sake of energy savings Sick House Syndrome is a real issue. Homes and dorms and apartments are not like HD/Lowes with constantly opening doors and ceilings set at 22' for storage purposes. The sealed up house or dorm might take a few 3D prints to build up formaldehydes or dioxides or sulphur gases sufficient to measure but by then your lungs are screaming for help Bottom-line don't for ONE second think that 3D printer filament is all safe and that they are all similar. The cheap Asian stuff has had tiny ball bearings inside as well as foreign compounds that were unable to be determined by basic techniques. Add some heat to that and see what gasses out. Surely I would never print without sufficient ventilation and if you insist on building an ABS enclosure you MUST vent it before going inside to recover the print. I suggest a long section of shopvac type hose connected to a Shop Vac unit exhausted outside with another section of hose OR put the whole printer in the garage or on an open deck if the weather allows Looking back a long time ago I can remember working on antique and muscle cars and grabbing the good old air hose with the trigger adapter on it and blasting the entire wheel well area and the brake areas and the inner wheel spaces. Now no one stupid enough to have done it is around to discuss it What we all assume is fine today might be found to be no so fine in 10 or 20 years just be careful and use your head. if you can use Fusion 360 you have the intellect to know about ventilation and distance vs concentration curves.

Resin is no worse than any epoxy in terms of fumes. You need adequate venting, thats all. BTW, if you had a sudden reaction, you have probably were exposed to that solvent previously. The whole printer should be in a vented hood.
Sorry to you are so Wong it’s not funny. This is bad stuff just read the data sheets on this as well as the post in this thread from a medical doctor and the of cases he alone has treated...
Not quite for the WD7, but I had a question about the MP Select Mini! I was reading about upgrading the hotend to a E3D clone and I noticed that it said that I should attach a fan to the 12V power supply. I was just wondering whether this is possible without soldering anything onto the motherboard? Thanks!
You will have to solder, but if you look at the play list on my channel for the mini I show how do this as well as I have published a mount on thiniverse for a 50mm fan as yes it would be a good idea to add as stock its under cooled...
So if I wanted to change the fan in the future, I'd just have to strip it and attach using the wires in the future right? And will one 40mm be enough using this mount? www.thingiverse.com/thing:839620 Thank you very much! :-)
I had some of the same concerns, but I think the odor is the worst part. I actually had this printer running for a few solid days in my office (bad prints and mistakes I shouldn't have made) and the fumes got bad -- and then I realized my cockatiel was sitting next to my desk and had no problem at all. Birds are super-sensitive to chemicals (cooking on teflon frying pans can kill them) but Gizmo's fine. I would suggest ventilation and rubber gloves, but the other resin I got doesn't have that same odor. I'm wondering if it's the difference between the Chinese resin and the resin we get from the states. ruclips.net/video/Zn-XdT0rSok/видео.html
Not really, there is NO comparison between resin and ABS as well you have zero scientific basis for making such a statement. If you look at my series on 3D printing and air quality I show the impact of ABS and it is NOT even close to resin. While I was the first to sound the alarm bell on this and took a lot of negitive comments. Now, all of the other 3D printing RUclipsrs have followed with their own warnings on resin.
It's because there's a difference between a smell/hazard warning and all the alarmist BS you're spewing here. This is basically a Buzzfeed video except less viral and more misleading. Also, you took a LONNNNNG time to get to the point, only to say "IDK guys, I didn't like the smell". Why you returned the whole thing instead of throwing the demo resin away and getting a safer one is beyond me.
It's good you made a video about this issue. However, I think you could put your setup in a bigger box with an activ carbon filtering system and you shouldn't have major issues.
In correct, this is the point as resin printers require air evacuation systems simple carbon filtration or HEPA filters will be of no or little use. These are commercial grade chemical and not intended for home use , in fact one of my long time viewers a medical doctor even wrote a comment on the number of serve cases of exposure he was seeing at the hospital he works at. You can read it here: diy3dtech.com/dr-daves-post-on-resin-based-printers/
Could organize your presentation a bit better. Do use a respirator and an exhaust fan (that you know actually leads outside). Have to wonder about Chinese resin. Lead paint on toys, melamine in the pet food, problems with drywall (en.m.wikipedia.org/wiki/Chinese_drywall)... At the same time, Japanese products used to be poor quality, and look at them now. China can do the same thing some day.
First would suggest reading this: diy3dtech.com/dr-daves-post-on-resin-based-printers/ as this stuff was not intended for residential use as it is nasty even with a respirator as it will settle into your surroundings. Also, even with ventilation, your just exhausting for your neighbors to breath in and is that right? There are just some things which do not belong in a residential setting and the current versions of resins are those as people (as covered in Dr Daves note) in general are not equipped to handle such chemicals...
I use SLA printer for work and i like and hate this technologies at the same time. and the worst of it is user clean the print in the sink. there is a lot of heavy metal in the resin as Antimoine. i think it should not be legal to sell Sla printer as Hobby printer.
Thanks for sharing and I agree with you as all of this is being washed down into a municipal water treatment system which were never intended for wastes such as this on top of placing it in the hands of unskilled hobbyists...
DIY3DTECH.com when we work with the resin. We keep the expire and damage resin appart. And even the isopropanol that we have clean the part in and we give it to the eco-center here in montreal. They put it with the chemical waste
Here is a link in the formlabs page talking about how to dispose the resin. they mention to never pour any resin in the drain support.formlabs.com/hc/en-us/articles/115000018044-Resin-Care
I appreciate the safety first methodology here, but you are using misinformation to carry your point which isn't cool. The MSDS represents the risks that you claimed to have exhibited via contact with the skin, not via "gas exposure" and you made it clear this was via the air and not direct skin contact. Having reviewed the entire form, they MSDS does not claim this product SHOULD cause the issues you experience. You may have an unfortunate, yet unique, allergy to the resins that may be causing this instead. Further, Your "Doctor" claims that issues can also occur with PLA and ABS printing, which you continue to use. Maybe its been posted elsewhere, but I would like to know this medical professionals FULL NAME and accreditation (schooling and some form of career). I myself love the idea of working safe and then smart, but I can't condone this hysteria over misinterpreted data sheets and some "Dr DAVE!". Don't stop posting, keep the content flowing, but consider cross checking your data before posting.
My friend, exposure by gas is far worse then skin, I have worked for many year in or related to the application industrial hygiene and this is bad stuff and you can read more here from a medical doctor as what he saw just in his emergency room... diy3dtech.com/dr-daves-post-on-resin-based-printers/ (you many need use the zoom function view better...
In case you havent figured it out yet, this is called optical resin and you should use gloves and its advisable to use goggles too then you'll be fine. thousands of people use these machines every day and are fine..
Really? So Han your a medical doctor and have scoured the world regarding this? Well you should read this from a "real" medical regarding cases at only his own hospital. diy3dtech.com/dr-daves-post-on-resin-based-printers/
Good call, I am no stranger to 3DP and CNC, in industry SLA and similar material printers had some of the strictest safety protocols available, resins are nasty stuff and I don't think it is suitable at the moment for the home environment especially where children are involved. Regards RobUK
Must say I was surprised! Within minutes my eyes where irritated and that is what set me off looking at the MSDS sheet I was shocked and saddened as I had such high hopes to work with resin. However was not worth the heath risks...
Thank you! I was hoping to get one of these but with two children I now realise it would have been a big mistake! I'll stick to lasers and fdm :-) keep up the good work.
Thanks for sharing however if you look up "SLA" you will find stereolithography apparatus, optical fabrication, photo-solidification, or "resin printing" whereas the DLP portion more so refers to the "means" of image creation (projection) where SLA is typically laser based. This is like saying Formica and referring to a "counter top" as the main point here is "resin printing" and not the light source.
I looked at a several others (not claiming it was an exhaustive search), however I saw none that where "not toxic". Would seriously be interested if there was one an you could share it as I love the idea of SLA printing as I had several commercial ideas for this which are now down the tubes due to this...
DIY3DTECH.com Fun To Do from the Netherlands has a broad range of good quality affordable resins. Their products are worldwide available. For the U.S. the distributor is studioqubed@gmail.com you can get specific info about their resins emailing them. About the non toxic side, I haven't heard yet of excessive odours, but it's always best to use resin printers in a ventilated area. When a resin gives you instant health problems, just quit using the resin altogether, not all resins are a like in terms of toxicity, but always operate in a well ventilated area.
Love the Netherlands (spend a lot of time in the Haag and the reason my site Colors are orange!) ventilated area is the key as if it was a garage or the like would agree however my shop is in the basement and I have installed a ventilation system and still could not deal with it. Again in looking I have not found what I consider a safe for home use (also know a thing or two officially on MSDS specs and hazardous materials) that I would expose my family too. However the search will continue :-)
All Acrylate based resins are toxic. That's a fact - end of story. Selling hobbyist level machines that use this stuff is a ticking time bomb because few hobbyists will observe the required ventilation requirements.
Wish it where that easy :-) This stuff gets all over as you have to wash it, cure it, etc... Oh and you vent it out the window, what about the neighbors :-)
Calm down guys. He's not telling you not to print or not to use a DLP/SLA printer. He's simply trying to caution people and put some useful information out there. If you don't find this particular information pertinent to you, continue on to the next video.
Thanks for the kind comment, yet I don’t worry about these comment because as you say I am only sharing facts and if someone wishes to expose themselves to these hazards then so be it is their life they are tossing away...
I wish I could unlike you three times as you clearly have no clue the risk this creates for the user. As this product should not be offered into the consumer market...
7 minutes of you complaining about something you should have taken the time to do due diligence for. You make it sound like a nightmare, but in reality you said over and over again - you screwed up. Wear PPE, read the SDS, and stop whining :) I see where you're trying to help others, but sounding sensationalist about the dangers of a 3D printer is tiring. Go take a whiff of Windex and tell me it smells any better than uncured resin. Heck you probably put gasoline in your car on a regular basis - want to do a video about how bad that stuff is? Also, and lastly, there's a reason larger SLA machines cure unused material and drain waste into a sealed container. :)
I am helping others avoiding ending up in the same boat as this is just something you don’t think of and if you unhappy with that I am sure there are Mash reruns you would enjoy 😊
PS I am also sure you will leave an open canister of gas in your home while you breath it for hours on end. Did you really think about what you wrote? All I got to say is buy and breath really deep around it 😊
Because of your "probably put gasoline in your car on a regular basis" makes no sense. As when I refuel my car I am out doors and using equipment that was purpose designed for exchanging fuel. As if you have not notice modern gas pumps have "fume reducing nozzles" for this very reason. So you wan to carry out an "accurate" analogy, this would be akin to placing a canister of gasoline in your home and allow the the gas to vaporize so you breathe it in like this printer. Common Windex really? Again no comparison if you look at the MSDS sheets, the resin material was not designed for "home" use, it is an industrial compound and not intended to be used in the "home". If you read down the thread you see the comments of regarding this. As open the resin container in my shop which is relatively well ventilated I had a allergic reaction to it which is what sent me quickly the MSDS sheets for the product. Also these folks have also written up similar here: www.fabbaloo.com/blog/2015/11/5/3d-printing-materials-toxicity-assessment-yes-toxic
My only takeaway from this is that you neglected to read the MSDS before using the stuff. This is not a judgement on the material as much as it is a judgement on you.
PLEASE READ BEFORE COMMENTING OR USING AN SLA PRINTER! In my latest video on air-quality and 3d printing there was a post by a medical doctor which I am reposting here for reference you can see the original here ( ruclips.net/video/vc-0yeWowYk/видео.html ) :
"Joe sorry I have been out of pocket for a few episodes and I noticed this episode. Unlike you, I am a doctor and have spent almost 4 decades slicing and dicing the human body. The MSDS sheets that are required by every company that sells to another company that has employees are irrevalent for consumer activity
The assumptions are that in a business or industrial use the ventilation will be much different, the typical building construction is much different, and most importantly the user will typically be isolated from the direct effect of the outgas as opposed to having a 3D printer in the den or in some cases the dorm room where you sleep
I am not as concerned about PLA as I am ABS. NO doubt that ABS is a non-consumer based product in terms of manufacturing uses. It IS one of the most used plastic in the world but that is post-processed. Sure it can be used as many do no different then anyone can change their own brakes but realizing that brake pads/shoes are made up of asbestos which we are 100% sure is a carcinogen. Mechanics know the risks and mitigate at every opportunity.
The REAL bad boy is still to be gone over. The SLA resins are the bigger issue
Just in the past 12 months, we have had two bouts of ED visits leading to admission. Inhaling that stuff is SUPER nasty. The one episode was a girl and her dad and the other was a mature college student (mature in age not so in intelligence)
The two totally independent episodes claimed they followed the directions completely the college kid used his resin printer in his dorm room with no special care or vents or even taking it into the common space. It overtook his lung capacity and he passed out. Post-exposure he lost all memory and to my knowledge has never gotten it back (a VERY serious situation showing how much brain damage was caused in a short time)
The two family members who were just learning resin printing followed the instructions and actually brought the resin into the ED so we could analyze it. The father was in the ICU for a few days and then needed to see a pulmonologist for lung care follow up
This stuff is NO toy; as we push the limits of temperature in order to get better prints we also push the gases out of the material and that causes the issues. Also, many of these compounds that might be imperceptible on meters like Joe is using after a week or 4 of printing have built up to serious levels
More and more homes are actually sealed better than any other building we encounter for the sake of energy savings
Sick House Syndrome is a real issue. Homes and dorms and apartments are not like HD/Lowes with constantly opening doors and ceilings set at 22' for storage purposes. The sealed up house or dorm might take a few 3D prints to build up formaldehydes or dioxides or sulphur gases sufficient to measure but by then your lungs are screaming for help
Bottom-line don't for ONE second think that 3D printer filament is all safe and that they are all similar. The cheap Asian stuff has had tiny ball bearings inside as well as foreign compounds that were unable to be determined by basic techniques. Add some heat to that and see what gasses out.
Surely I would never print without sufficient ventilation and if you insist on building an ABS enclosure you MUST vent it before going inside to recover the print. I suggest a long section of shopvac type hose connected to a Shop Vac unit exhausted outside with another section of hose OR put the whole printer in the garage or on an open deck if the weather allows
Looking back a long time ago I can remember working on antique and muscle cars and grabbing the good old air hose with the trigger adapter on it and blasting the entire wheel well area and the brake areas and the inner wheel spaces. Now no one stupid enough to have done it is around to discuss it
What we all assume is fine today might be found to be no so fine in 10 or 20 years just be careful and use your head. if you can use Fusion 360 you have the intellect to know about ventilation and distance vs concentration curves.
Dr Dave"
Way too much drama and stressing your point over and over again. I get it, it's bad stuff. Now my question is you talk about ventilation. If you have a good enclosed ventilation system you should not be smelling any fumes. So a better video would be about what you did to fix the problem of breathing the toxic fumes and what kind of gloves you wear when handling the parts.
I have a enclosure made out of PVC pipe for the frame with foil cover insulation foam board aluminum taped to the PVC pipe. Its power vented using a inexpensive radon vent fan and I use a 3 inch gate valve to control the air flow. Yes it blows outside. Super inexpensive setup and super safe. I lite up the box with LED under cabinet lights and I have a smoke detector mounted near the air exhaust just in-case.
If you like respitory injury sure no drama as this stuff is VERY BAD, one of my viewers a Medical Doctor wrote me about this (you can see the post here: diy3dtech.com/dr-daves-post-on-resin-based-printers/ ) after making becuase just in his hospitial they have seen so many cases related resin printers . As yes you can vent it and they do make vent hoods for this (this is how these are handled in commercial settings) as you too have have to deal with the cleanup of the parts and this stuff gets all over (so your also just flush this down sewer for your local municipality to deal with or worse yet into a septic and contaminate groundwater? See here is the point, yes you can do a lot of things in your home, however is that the right thing to do? So the fumes evacuating from your home, what about your neighbors? As I can build a Farnsworth Fusor in my basement and expose my family and neighbors to high level of neutron radiation too, is that right just because I can do it?
Not to diminish your warning... But I open my first bottle of UV resin and within minutes the entire house smelled an awful chemical poisonous smell. I had the family go outside and I ventilated the house. Then I asked on a forum. No one else had experienced that even with the same brand. So I opened another bottle and there was very little smell. After digging up information I found that the UV resins usually have low VOCs and the risk is with skin contact and not inhalation. I can't explain what happened to that defective bottle, but I felt safe getting rid of it and using the others with moderate ventilation.
Thanks for sharing, actraly had two bottles of differing brands and had a reaction to both. I wouldn't say the smell it self was over whelming it was more so the reaction to it and after reading the MSDS wasn't worth it me...
Made in china... They do not care about health, they pollute, destroy the environment, there are thousands of Chinese products that do not meet any safety requirement and enter all countries without having controls, well-known brand water bottles that do not comply with anything and contaminate food , the same kitchen utensils and pots, plastics that have toxicity, asbestos in materials that should not have them, they are an industry of terror but they disguise it as something normalized.
DLP not SLA, huge difference. You may have a bad batch or resin, if the smell is that intense something is wrong. I find it hard to believe that you did not account for fumes before you bought the printer or even research the possibility of them
I understand the difference and it moot as both are resin based and no on the bad batch concept (I tried several brands). The point is this stuff is not intended for in home use (you can read the SDS sheet if you want to disagree as they are very clear they contain bad things and the links are in the description). Also this is why I did this video as do "you" take into account every aspect of everything? It simply isn't possible as when you make a purchase such as this your expectation is there is relative level of safety. Also it's less about the how noxxious the fumes are, but more so how "toxic" (again read the SDS) they are...
And this is also why you wear gloves and air well when working with epoxy, the amine hardener is same thing, just a lot less active. It's possible to become allergic to it over time.
Correct...
I'm guessing you did a lot of research on SLA printers in general before purchasing this one... given just how many warnings there are out there about materials like UV-activated resin, I am just amazed that you didn't anticipate this as being a problem or something you should look out for. You could have seriously injured yourself or a pet or another person. Sorry to seem harsh, and I'm glad you put the video out... but... I honestly am just surprised.
In addition, you're using things like Laser Cutters - -how about the off-gassing from the materials you cut there? If you've already got a ventilation system that can handle things like aluminum laser cut off-gassing, I would think you could utilize it very easily to do SLA Printing.
Actually not and the reason I made this video when I did because this video is getting rather old now and no there was very little out there on SLA printers at that time. Also this is being sold to Joe consumer which has no idea about MSDS sheets and the like and assume that since it is being sold its safe (a common misconceptions Americans have). In fact this is supported by this post (diy3dtech.com/dr-daves-post-on-resin-based-printers/) from a doctor from just one hospital and the cases he has seen. Now to your question about lasers, a far different animal as yes there are fumes but also depending on the material may or maynot be nastier, yet if you have followed my videos you see I am big on fume extraction and this is key. Now what folks like yourself miss is there are people who are unknowing buying this for their kids and as in the post there are bad things happening as yes trained people handle poisonous snakes all day but that does not mean that is suitable for the public. The other difference in laser verses SLA is the fumes are confined in the laser however this SLA resin get all over as its a messy process so yes I could have installed it in a fume hood as I have done with my ABS printers (as that too is nasty) yet again as you wash the SLA and cure, you cannot but help get the stuff all over so a major difference. Its worth keeping in mind a residential home is NOT a factory and they are designed and situated that way for reason as even with fume evacuation your making your problem your neighbors problem and is that right? Just think do you want your neighbors giving your kids cancer?
Only a totally careless person would buy a device like this for their kids without doing the research first. Only a totally careless person would run this machine or handle UV resin in a shared environment. I saw the post by the doctor and I TOTALLY AGREE. This is what I don't understand: you are basically the person that made these mistakes. Yet, you still don't know whether or not off-gassing from lasers "may or may not be nastier". This is what is so confusing... figure it out, especially if you have children, pets, or other living things around. JUST THINK: do you want your neighbors giving your kids cancer?
LOL! "Only a totally careless person would buy a device like this for their kids without doing the research first"! Happens all day long! Most of what I do with the laser is engraving so very little outgassing as well as any cutting is either wood or cast actrylic and I live in a bit of rural setting as not to give the neighbors cancer. Yet I have people write me all of the time about using lasers in apartment building! That is wacked! Yet the key here is it's easy to evacuate a laser and not so easy for SLA as you can do every thing under a fume hood in your home and second it gets all over...
As some other fellows say, you might have a defective sample. I have been using the orange sample Wanhao sent me with their printer, and even the smell is strong, I have had no problem with it. I have started using FTD resins, and the smell is less intense than the sample.
That being said, I agree with other fellows and encourage everyone to wear respirator, safety goggles and gloves when handling resins. When things are done properly, the experience is way far from being a life threatening one.
Also, I don't think a resin print runs longer than a FDM one: while an FDM head has to run through all the paths to print a model, the D7 projects the whole section of the geometry from the LCD to the resin. Plus you do not need infill.
Tried two different brands and for clarity it not so much the "smell" but the "fumes". Now a very important point here is what the MSDS sheets say is "bad" so even if you don't smell anything there still are "fumes" which are bad and you are are exposing your self to bad stuff. Again not preaching, but people people seem to confuse smell and toxicity, however Carbon Monoxide has no smell but will kill you. So please be safe my friend :-)
Different people have different levels of sensitivity to a particular chemical. An example is peanuts: most people get nutrition from eating them, however a few go into anaphylactic shock and can die. Figure out which you are for these resins.
One problem to avoid is getting more sensitive when your body is exposed to something too much. E.g. think about having sore feet. Stop walking, you feel better tomorrow. Keep walking on them and develop bloody blisters.
Use good ventilation, and be sure about where the exhaust fan is sending the fumes. E.g. some bathroom exhaust fans aren't hooked up to a roof vent and just blow into the attic.
Good video
Lot of people attacking you for not doing research which is sort of fair
I am glad you've raised this point as I'm looking to buy this and was not previously aware of this so your video has served it's purpose
Thanks
Thanks yet if you read down the thread have done my home work and even supported by a medical doctor: diy3dtech.com/dr-daves-post-on-resin-based-printers/
I just put an order on this printer, I plan to keep it in a well ventilated space in my basement, and I only ever handle resin when wearing a mask, glasses, latex gloves, until everything is cleaned up and the print is fully cleared
Cured
Since it is inside the air envelope of your home (i.e. basement) I would still suggest a negative pressure ventilation system as this stuff is nasty and while your protected for the moment, the chemicals will linger and settle in your home no good for other family members or pets...
DIY3DTECH.com ok, is there any “box, chamber, safe” that has a filter or something that you know of, the basement is my only option.
But you can use any resin. #HARZlabs for example. It has no odor at all, and it is antiallergic. But cost a bit higher.
Thanks, however the first myth to dispel is "no order" means nothing as it is not the smell which will harm you. Also, you need to read the MSDS (www.edv-3d-druck.de/media/pdf/2b/53/f1/MSDS-HARZ-Labs-Basic.pdf) not nice stuff, keep in mind the cured product is not the issue, its when its in a resin state. Like Asbestos, the solid version is safe however its when it breaks a part it becomes an issue. As it clearly notes: P261: Avoid breathing dust/fume/gas/mist/vapours/
substances in an atomized state. As it also it also states it should be used with local ventilation (i.e. fume hood)...
This was a waste of time it's not hard to find literature or videos that say there is a smell. You are also being very dramatic.
So you are you telling me everyone knows what an MSDS sheet? And everyone thinks about that? Also its more then just a "smell", as it appears you did not listen to nor read the inserts to the video? This is a health hazard, so what do I have to say about your "dramatic" comment? Buy one and breath deeply my freind:-)
I really liked the review, these things are not a joke to play around with. Long time exposure to different resins could lead to allergic reactions, this is the case with 2 component glues too, so be aware my friend! The other thing is that these chemicals might build up in your system, it is always a good idea to play it on the safe side, a proper gas mask and and a chemical protective suite is not expensive, not even by Eastern standards. Play it safe, and have fun, guys! :)
This video is ridiculously long to say about 30 seconds worth of material. You don't get to the point until 2:28. Alternative script: "Hi, I bought this, I didn't understand how strongly SOME people are sensitive to the materials, I was sensitive to the materials. I suggest you buy JUST some resin, open the jar, and if you feel an abnormal sensitivity, don't buy the printer. Thanks, bye."
Too bad you couldn't figure out a way to work this into your lifestyle. These are great little printers. I have the Photon and it has been a revelation. FDM almost seems archaic now. You're missing out. :-(
Its not really a fact of "working" it into ones life style as plain out the chemicals are dangerous and intended for for home settings. This article from a medical doctor share ER incidents from only his own hospital is worth a read: diy3dtech.com/dr-daves-post-on-resin-based-printers/
Good point on the hazardous nature of the resin but I might add that any resins are hazardous and to think that a machine that requires a resin would be anything other than hazardous is naive. Even super glues should be handled with gloves, respirator and goggles. If you want high quality prints then use in a well ventilated area with the right PPE. You should be doing that with ABS prints anyway, the off-gases from that are also hazardous. Im sure theres a whole plethora of chemicals in your workshop that are just as hazardous, just take the proper precautions.
In a way I was naive in thinking there would be "controls" but I should have known better (this should not be sold into a non commercial setting as people are going to be dumping this into the sanitary sewer, etc), however I am not sure I agree with you totally as there is a level of toxicity based upon volume as there is ton of stuff which is poisonous we come into connect every day with in low volumes like super glue. Also if you noted in the video I discussed the fact I do have a ventilation in the shop (mainly fro ABS and HIPS) and it could not deal with the fumes from this. As I expected out gassing, but not to the level which I experienced...
2:15 Problem: Fumes from the resin caused an allergic reaction.
Yes and I have work a lot with fiberGlass in the past too so not foreign to resins...
DIY3DTECH.com Repeated exposure to these types of chemicals are known to cause an escalating allergic reaction. This is important for people who are new to the trade to understand as it not only impacts the individual working with it, but also anyone in the nearby vicinity.
You are totaly right. Your video should be long as 20 sec. You repeated the same info over and over, picking up and putting down thw bottle for dozens of times. Thanks for your output.
You know the rule if you want people to hear it, you have to say it at least three times...
Great PSA, these resins are some serious stuff, glove and googles are an absolute must.
Yea an expensive one to. The main issue is the fumes, this really out gasses...
Interested in your opinion of the new Prusa resins. They seem to be much safer than this cocktail from China. The Prusa MSDS says that the fumes are safe to breathe so long as no misting conditions are present.
I would be highly surprised if this is the case as keep mind that MSDS typical refer to the "solid" state of the product and all resins work basically the same, do you have a link...
There are some safe resins, monomer free resins are supposedly non toxic. They are more expensive but worth the extra cost especially if your chemically sensitive. Also, some resins are much more toxic than others.
If you have a link to a "non-toxic" resin can you share it? While I have not looked in the past couple months, all the resins I did look at were all pretty much the same and because of this were intresiticaly toxic. However would love to see the MSDS sheets for a non-toxic version as that would be great even if more money :-)
Thanks for the warning, I'm thinking of getting an sla printer but have particular sensitivity to allergens and chemicals so this will be important to test out before I take the plunge. Better safe and informed than ignorant and sorry.
Yes, I can take a lot but this I could not. It needs to be used in a well ventilated area and two it is very messy so it get all over!
I've been reading a lot of reviews about this stuff and wondered about the safety of the resin. I was reading about the Monocure resin, which The Hot End suggested as being better than the included resin. Upon checking their website and downloading the SDS tab, the PDF says a lot of the same things you found ("Causes skin irritation", "May cause respiratory irritation" and so on). This disappoints me since I have seasonal allergies galore and mild asthma. I have a well ventilated shop in the basement of my home, but since these prints run so much longer than FDM, I am debating the risk.
That is the same as I found that they are all basically the same and my wife too has mild asthma and I just couldn't expect her exposed to that if it caused me issues. As yes when I ordered mine also bought a liter of the Monocure resin too and it was no different sorry to say as simply think about it, they all basically work the same so how different can they be? :-(
So I tied an onion to my belt, which was the style at the time. Now, to take the ferry cost a nickel, and in those days, nickels had pictures of bumblebees on 'em. Give me five bees for a quarter, you'd say. Ah, there's an interesting story behind that nickel. In 1957, I remember it was, I got up in the morning and made myself a piece of toast. I set the toaster to three: medium brown.Now where were we? Oh yeah: the important thing was I had an onion on my belt, which was the style at the time. They didn't have white onions because of the war. The only thing you could get was those big yellow ones...
Love onions, however I don't keep them on my belt...
I've tried many different Acrylate based 3D printer resins and while they are all nasty, the Wanhao resin is particularly horrid. It caused my eyes to burn when just getting near the printer when using it.
The bottom line is that any resin printer should be used in a very open area such as a garage with the door open, or else under a fume hood or box with exhaust fan. Acrylate resins are a serious health hazard because after you are around them for awhile you get numbed to the smell and don't notice it as much. But the toxic vapors are accumulating in your bloodstream will eventually cause neurological damage if you continue to expose yourself to them.
You are 100% correct, that is what what people don't realize about these printers and even using in fume hood, the resin tends to get on everything as it is a very messy process...
So you are allergic to that resin... yes, there are others out there with varying levels of outgassing... many of the other chemicals you are likely using in your shop have MSDS sheets that are worse or equivalent to the resin... While I concur that effective ventilation and protective gear are much preferred, also note that the outgassing of that ABS is also equivalent (and can equal some resins)... any time you are working with chemicals or "burning" (like with that Laser cutter) you are exposing yourself to those VOC's... You may wish to check on some of those MSDS for your other chemicals and equipment and/or increase the active ventilation... Also, burning wood is far *more* toxic in many ways, as is the rosin core of that roll of solder I see... Good for applying caution and (finally) researching all the facets of an activity... loss of a few points in making it sound a bit more "horrific" than it really is. Your sensitivity is higher than a lot of others. That is part of the reason that the verbiage said "May" on the MSDS...
Thanks for commenting as no my sensitivity is higher than a lot of others and yes looked at them all and while slightly different they all need work the same and are far worse than ABS ever thought of being. In fact on my latest video on air-quality a (medical) doctor posted what will follow and it is clear people are being immediately harmed by SLA resin as this was not intended for "home" use but as an industrial chemical in an industrial setting. So here is the quote and print safe my friend:
"The REAL bad boy is still to be gone over. The SLA resins are the bigger issue
Just in the past 12 months, we have had two bouts of ED visits leading to admission. Inhaling that stuff is SUPER nasty. The one episode was a girl and her dad and the other was a mature college student (mature in age not so in intelligence)
The two totally independent episodes claimed they followed the directions completely the college kid used his resin printer in his dorm room with no special care or vents or even taking it into the common space. It overtook his lung capacity and he passed out. Post-exposure he lost all memory and to my knowledge has never gotten it back (a VERY serious situation showing how much brain damage was caused in a short time)
The two family members who were just learning resin printing followed the instructions and actually brought the resin into the ED so we could analyze it. The father was in the ICU for a few days and then needed to see a pulmonologist for lung care follow up
This stuff is NO toy; as we push the limits of temperature in order to get better prints we also push the gases out of the material and that causes the issues. Also, many of these compounds that might be imperceptible on meters like Joe is using after a week or 4 of printing have built up to serious levels"
I am not going to deny that some things can be dangerous if handled poorly... I can easily point to the old plastic model glue that some started to "concentrate and inhale in order to get "high"... Not it's intended use or a safe way to handle it and obviously proper ventilation was completely ignored... and yet millions of people understood the "risks" and handled it properly with no issues.... No, 3D printing is not a Star Trek Replicator... it is an industrial tool that has been modified (and price reduced) to be within the reach of an average user. That being said, one should learn about the tool, any hazards involved, and how to mitigate or eliminate those hazards. Just like other household and even shop appliances/tools, there are things you do to safely operate them (Don't stick Tupperware in an oven, don't stick a knife in a toaster, don't use any corded item in the shower) there are also people who don't observe or ignore those warnings (for whatever reason) who will continue to populate the ER of hospitals in response to their actions. I am not trying to cownplay either of those instances, it is quite likely to be seen in other places and by other doctors... The point is to respect the needs and requirements of the tools we choose to use, and observe reasonable safety precautions.... or don't use them!
Really... Names and citations or it's just hearsay... Two, only two... and the so called symptoms... fascinating way he describes them... I'm also laughing about this "doctor" description of "pushing temperatures higher to get better prints" this prints at room temperature, there isn't even a heater involved... he appears to be mixing different technologies... then there is the "Week or four of printing" where those compounds have built to serious levels... maybe in a closed room where no one ever enters or leaves so there is no air exchange or ventilation... then again, if you stayed in a small room with no air exchange just breathing, the CO2 content from your own breathing will knock you out long before the first week... Your "doctor" makes a bunch of very interesting claims but then does nothing to back them up... he goes on to make some rather dubious (if not outrageous) claims later on.. "Tiny ball bearings in cheap Asian stuff" seriously? As I stated before and will reiterate here...
Bottom line, these are tools and chemicals... just like any other tool or chemical compound, there are certain safety precautions that you take to handle them... Use them according to instructions and all is good, ignore them and bad things can happen... for instance, try mixing typical household bleach and ammonia... hope you like toxic chlorine gas... but they sit under the kitchen sink just fine and behave themselves if you follow directions and don't mix them... Safety is being aware of your surroundings, understanding consequences of actions, and taking appropriate precautions... if you choose to ignore these you will self select out of the gene pool... fear mongering is useless, education, understanding, and proper precautions works wonders...
You are pre sensitised to the resin. You obviously have exposed yourself to epoxy resins in the past. You should never let any epoxy get on your skin, you should always wear gloves. Now if you hadn't repeatedly exposed yourself to epoxy resins in the past and pre sensitized your system. You would not of had a bad reaction or in fact any to the resin. That's the problem with SLA you start good and then as you expose yourself bit by bit to the resin your system gets more and more sensitive to the resin till it becomes impossible for you to work with it. So to all you people who like to use your fingers to apply epoxy or not wear gloves you are setting yourself up to get really sick if you try to use an SLA printer. Me I can't go near the stuff been playing with all types of epoxy resins for fifty years and my system will react badly. So if you don't react now, keep it that way by wearing gloves and respirator and you will not have a problem.
Thanks for commenting as the issue is if this is a possibility due to sensitivity, this is bad [as in hazardous] stuff. Take cigarette smoke, one can get use to it, yet it will kill you slowly and the SDS is clear. Resin is nasty stuff and yes while wearing gloves and respirator may help me, issue becauses what about my family member and pets? Because of HIPPA they can't publizie the data, however though friends in the respiratory community i have learned of 4 serious inhalation cases resulting in serious lung damage.
DIY3DTECH.com I agree, my main point was people use common chemicals and don't take proper precautions because of it's just epoxy, it's just solvents. The chemicals won't necessarily kill you now but they will effect you down the line. How many people watching have a FDM printer in their bedroom. PLA it's safe, but the particles are not good to breath in a enclosed space.
Yes you are correct "people use common chemicals and don't take proper precautions because of it's just epoxy". Did you see my latest video on ABS?
Holy heavens ... I do not want to die of cancer or something because I'm playing recreate my toy models at home ... is it really poisonous or chemically dangerous?
Yes, simply read the MSDS (material safety data sheet) for yourself in the link I provided in the description...
the monocure resin i am using smells weird and i was asked to move it out of the house as the missus started to feel nauseous and got a headache-it was only in the house 2 days. I had no issue and I was closer to it and got it on my hands quite a few times, which I washed off immediately.
Different people react in different ways, however even if doesn't "bother" you at the moment. It is still important to read and understand the MSDS sheet as it is some nasty stuff...
yes agreed- i have chemical handling experience and it is all now in the shed with good ventilation and all the rags and wash pots and stuff get stored in a containment box and prints are also handled as "dangerous until post curing has stopped the strong smells coming off"-I dont know if you have come across the story of the girl who was using 3d printed containers to grow her experimental zebra fish in-----fish eggs all died and they found that post process curing reduced egg death.
No but not surprised and would still be concerned it only reduced and didn't eliminate the fatality rate. Just be safe my friend I need all the viewers I can get :-)
Made in China .They do not care about health, they pollute, destroy the environment, there are thousands of Chinese products that do not meet any safety requirement and enter all countries without having controls, well-known brand water bottles that do not comply with anything and contaminate food , the same kitchen utensils and pots, plastics that have toxicity, asbestos in materials that should not have them, they are an industry of terror but they disguise it as something normalized.
SDS Says......
Health = 0
Fire = 0
Reactivity = 0
Gimme a break, this stuff isn't bad at all.
LOL! Your smoking the dope! Can tell your NOT a medical doctor! Read what a real medical doctor has to say! diy3dtech.com/dr-daves-post-on-resin-based-printers/
meanwhile you print with FDM ABS, LOL!
Sort of, yet assume you also saw the saw 3D Printing Air Quality playlist (ruclips.net/p/PLInTrkIbj69kz2Uf_c3JIIzgwvDdUEsPO&disable_polymer=true) where I only print ABS & HIPS with external ventaltion as well as the test which I performed on ABS. Also, while ABS is not nice, there is no comparison between the dangers of ABS and resins to be very clear. Also I will re-post below a comment from a medical doctor who on the ABS/HIPS thread shared the patients he has come into just his hospital that were overcome by resin (You can read the complete thread here: ruclips.net/video/vc-0yeWowYk/видео.html&list=PLInTrkIbj69kz2Uf_c3JIIzgwvDdUEsPO&index=2 ):
Joe sorry I have been out of pocket for a few episodes and I noticed this episode. Unlike you, I am a doctor and have spent almost 4 decades slicing and dicing the human body. The MSDS sheets that are required by every company that sells to another company that has employees are irrevalent for consumer activity
The assumptions are that in a business or industrial use the ventilation will be much different, the typical building construction is much different, and most importantly the user will typically be isolated from the direct effect of the outgas as opposed to having a 3D printer in the den or in some cases the dorm room where you sleep
I am not as concerned about PLA as I am ABS. NO doubt that ABS is a non-consumer based product in terms of manufacturing uses. It IS one of the most used plastic in the world but that is post-processed. Sure it can be used as many do no different then anyone can change their own brakes but realizing that brake pads/shoes are made up of asbestos which we are 100% sure is a carcinogen. Mechanics know the risks and mitigate at every opportunity.
The REAL bad boy is still to be gone over. The SLA resins are the bigger issue
Just in the past 12 months, we have had two bouts of ED visits leading to admission. Inhaling that stuff is SUPER nasty. The one episode was a girl and her dad and the other was a mature college student (mature in age not so in intelligence)
The two totally independent episodes claimed they followed the directions completely the college kid used his resin printer in his dorm room with no special care or vents or even taking it into the common space. It overtook his lung capacity and he passed out. Post-exposure he lost all memory and to my knowledge has never gotten it back (a VERY serious situation showing how much brain damage was caused in a short time)

This stuff is NO toy; as we push the limits of temperature in order to get better prints we also push the gases out of the material and that causes the issues. Also, many of these compounds that might be imperceptible on meters like Joe is using after a week or 4 of printing have built up to serious levels
More and more homes are actually sealed better than any other building we encounter for the sake of energy savings
Sick House Syndrome is a real issue. Homes and dorms and apartments are not like HD/Lowes with constantly opening doors and ceilings set at 22' for storage purposes. The sealed up house or dorm might take a few 3D prints to build up formaldehydes or dioxides or sulphur gases sufficient to measure but by then your lungs are screaming for help
Bottom-line don't for ONE second think that 3D printer filament is all safe and that they are all similar. The cheap Asian stuff has had tiny ball bearings inside as well as foreign compounds that were unable to be determined by basic techniques. Add some heat to that and see what gasses out.
Surely I would never print without sufficient ventilation and if you insist on building an ABS enclosure you MUST vent it before going inside to recover the print. I suggest a long section of shopvac type hose connected to a Shop Vac unit exhausted outside with another section of hose OR put the whole printer in the garage or on an open deck if the weather allows
Looking back a long time ago I can remember working on antique and muscle cars and grabbing the good old air hose with the trigger adapter on it and blasting the entire wheel well area and the brake areas and the inner wheel spaces. Now no one stupid enough to have done it is around to discuss it
What we all assume is fine today might be found to be no so fine in 10 or 20 years just be careful and use your head. if you can use Fusion 360 you have the intellect to know about ventilation and distance vs concentration curves.

Perfect for printing Stout Hearted Heroes on! From Rocket Pig Games check the minis out if you already havent.
Okay..
Resin is no worse than any epoxy in terms of fumes. You need adequate venting, thats all. BTW, if you had a sudden reaction, you have probably were exposed to that solvent previously.
The whole printer should be in a vented hood.
Sorry to you are so Wong it’s not funny. This is bad stuff just read the data sheets on this as well as the post in this thread from a medical doctor and the of cases he alone has treated...
Not quite for the WD7, but I had a question about the MP Select Mini! I was reading about upgrading the hotend to a E3D clone and I noticed that it said that I should attach a fan to the 12V power supply. I was just wondering whether this is possible without soldering anything onto the motherboard? Thanks!
You will have to solder, but if you look at the play list on my channel for the mini I show how do this as well as I have published a mount on thiniverse for a 50mm fan as yes it would be a good idea to add as stock its under cooled...
So if I wanted to change the fan in the future, I'd just have to strip it and attach using the wires in the future right? And will one 40mm be enough using this mount? www.thingiverse.com/thing:839620 Thank you very much! :-)
I had some of the same concerns, but I think the odor is the worst part. I actually had this printer running for a few solid days in my office (bad prints and mistakes I shouldn't have made) and the fumes got bad -- and then I realized my cockatiel was sitting next to my desk and had no problem at all. Birds are super-sensitive to chemicals (cooking on teflon frying pans can kill them) but Gizmo's fine. I would suggest ventilation and rubber gloves, but the other resin I got doesn't have that same odor. I'm wondering if it's the difference between the Chinese resin and the resin we get from the states.
ruclips.net/video/Zn-XdT0rSok/видео.html
Nope no difference and would suggest reading the MSDS sheet, you will not want to sit next to it...
This is the equivalent of returning an FDM because they didn't like the smell of the demo ABS roll.
Not really, there is NO comparison between resin and ABS as well you have zero scientific basis for making such a statement. If you look at my series on 3D printing and air quality I show the impact of ABS and it is NOT even close to resin. While I was the first to sound the alarm bell on this and took a lot of negitive comments. Now, all of the other 3D printing RUclipsrs have followed with their own warnings on resin.
It's because there's a difference between a smell/hazard warning and all the alarmist BS you're spewing here. This is basically a Buzzfeed video except less viral and more misleading. Also, you took a LONNNNNG time to get to the point, only to say "IDK guys, I didn't like the smell". Why you returned the whole thing instead of throwing the demo resin away and getting a safer one is beyond me.
"I'm a pretty tough horse"...LMAO Yeah...ok.
LOL! Best-o-luck to ya :-)
It's good you made a video about this issue. However, I think you could put your setup in a bigger box with an activ carbon filtering system and you shouldn't have major issues.
In correct, this is the point as resin printers require air evacuation systems simple carbon filtration or HEPA filters will be of no or little use. These are commercial grade chemical and not intended for home use , in fact one of my long time viewers a medical doctor even wrote a comment on the number of serve cases of exposure he was seeing at the hospital he works at. You can read it here: diy3dtech.com/dr-daves-post-on-resin-based-printers/
Could organize your presentation a bit better. Do use a respirator and an exhaust fan (that you know actually leads outside).
Have to wonder about Chinese resin. Lead paint on toys, melamine in the pet food, problems with drywall (en.m.wikipedia.org/wiki/Chinese_drywall)...
At the same time, Japanese products used to be poor quality, and look at them now. China can do the same thing some day.
First would suggest reading this: diy3dtech.com/dr-daves-post-on-resin-based-printers/ as this stuff was not intended for residential use as it is nasty even with a respirator as it will settle into your surroundings. Also, even with ventilation, your just exhausting for your neighbors to breath in and is that right? There are just some things which do not belong in a residential setting and the current versions of resins are those as people (as covered in Dr Daves note) in general are not equipped to handle such chemicals...
I use SLA printer for work and i like and hate this technologies at the same time. and the worst of it is user clean the print in the sink. there is a lot of heavy metal in the resin as Antimoine. i think it should not be legal to sell Sla printer as Hobby printer.
Thanks for sharing and I agree with you as all of this is being washed down into a municipal water treatment system which were never intended for wastes such as this on top of placing it in the hands of unskilled hobbyists...
DIY3DTECH.com when we work with the resin. We keep the expire and damage resin appart. And even the isopropanol that we have clean the part in and we give it to the eco-center here in montreal. They put it with the chemical waste
That is the correct way to handle it rather as most will simply wash it down the drain...
Here is a link in the formlabs page talking about how to dispose the resin. they mention to never pour any resin in the drain support.formlabs.com/hc/en-us/articles/115000018044-Resin-Care
I appreciate the safety first methodology here, but you are using misinformation to carry your point which isn't cool.
The MSDS represents the risks that you claimed to have exhibited via contact with the skin, not via "gas exposure" and you made it clear this was via the air and not direct skin contact.
Having reviewed the entire form, they MSDS does not claim this product SHOULD cause the issues you experience.
You may have an unfortunate, yet unique, allergy to the resins that may be causing this instead.
Further, Your "Doctor" claims that issues can also occur with PLA and ABS printing, which you continue to use.
Maybe its been posted elsewhere, but I would like to know this medical professionals FULL NAME and accreditation (schooling and some form of career).
I myself love the idea of working safe and then smart, but I can't condone this hysteria over misinterpreted data sheets and some "Dr DAVE!".
Don't stop posting, keep the content flowing, but consider cross checking your data before posting.
My friend, exposure by gas is far worse then skin, I have worked for many year in or related to the application industrial hygiene and this is bad stuff and you can read more here from a medical doctor as what he saw just in his emergency room... diy3dtech.com/dr-daves-post-on-resin-based-printers/ (you many need use the zoom function view better...
In case you havent figured it out yet, this is called optical resin and you should use gloves and its advisable to use goggles too then you'll be fine. thousands of people use these machines every day and are fine..
Really? So Han your a medical doctor and have scoured the world regarding this? Well you should read this from a "real" medical regarding cases at only his own hospital. diy3dtech.com/dr-daves-post-on-resin-based-printers/
Good call, I am no stranger to 3DP and CNC, in industry SLA and similar material printers had some of the strictest safety protocols available, resins are nasty stuff and I don't think it is suitable at the moment for the home environment especially where children are involved. Regards RobUK
Must say I was surprised! Within minutes my eyes where irritated and that is what set me off looking at the MSDS sheet I was shocked and saddened as I had such high hopes to work with resin. However was not worth the heath risks...
Thank you! I was hoping to get one of these but with two children I now realise it would have been a big mistake! I'll stick to lasers and fdm :-) keep up the good work.
Many thanks 😉
Its DLP.. not SLA.
Thanks for sharing however if you look up "SLA" you will find stereolithography apparatus, optical fabrication, photo-solidification, or "resin printing" whereas the DLP portion more so refers to the "means" of image creation (projection) where SLA is typically laser based. This is like saying Formica and referring to a "counter top" as the main point here is "resin printing" and not the light source.
It is SLA and more specifically a subgroup of SLA known as DLP. Maybe you are thinking of SLS.
It's not even DLP as this printer uses an LCD panel for image creation, not a DLP projector.
There are a lot of other brands that are cheaper, better and not toxic like this brand.
I looked at a several others (not claiming it was an exhaustive search), however I saw none that where "not toxic". Would seriously be interested if there was one an you could share it as I love the idea of SLA printing as I had several commercial ideas for this which are now down the tubes due to this...
DIY3DTECH.com Fun To Do from the Netherlands has a broad range of good quality affordable resins. Their products are worldwide available. For the U.S. the distributor is studioqubed@gmail.com you can get specific info about their resins emailing them. About the non toxic side, I haven't heard yet of excessive odours, but it's always best to use resin printers in a ventilated area. When a resin gives you instant health problems, just quit using the resin altogether, not all resins are a like in terms of toxicity, but always operate in a well ventilated area.
Love the Netherlands (spend a lot of time in the Haag and the reason my site Colors are orange!) ventilated area is the key as if it was a garage or the like would agree however my shop is in the basement and I have installed a ventilation system and still could not deal with it. Again in looking I have not found what I consider a safe for home use (also know a thing or two officially on MSDS specs and hazardous materials) that I would expose my family too. However the search will continue :-)
All Acrylate based resins are toxic. That's a fact - end of story.
Selling hobbyist level machines that use this stuff is a ticking time bomb because few hobbyists will observe the required ventilation requirements.
OK dude put all the printer in a box with a vent connected to a window problem solved!
Wish it where that easy :-) This stuff gets all over as you have to wash it, cure it, etc... Oh and you vent it out the window, what about the neighbors :-)
Or you know, use a different resin, not return the whole damn thing.
Calm down guys. He's not telling you not to print or not to use a DLP/SLA printer. He's simply trying to caution people and put some useful information out there. If you don't find this particular information pertinent to you, continue on to the next video.
Thanks for the kind comment, yet I don’t worry about these comment because as you say I am only sharing facts and if someone wishes to expose themselves to these hazards then so be it is their life they are tossing away...

Yes I have seen (and cared for) someone who died because of lung cancer and you right it is very painful...

Your welcome :-)
i wish i can unlike this twice! you clearly knew nothing about it before you bought it!
I wish I could unlike you three times as you clearly have no clue the risk this creates for the user. As this product should not be offered into the consumer market...
😂😂😂😂
7 minutes of you complaining about something you should have taken the time to do due diligence for. You make it sound like a nightmare, but in reality you said over and over again - you screwed up. Wear PPE, read the SDS, and stop whining :) I see where you're trying to help others, but sounding sensationalist about the dangers of a 3D printer is tiring. Go take a whiff of Windex and tell me it smells any better than uncured resin. Heck you probably put gasoline in your car on a regular basis - want to do a video about how bad that stuff is?
Also, and lastly, there's a reason larger SLA machines cure unused material and drain waste into a sealed container. :)
I am helping others avoiding ending up in the same boat as this is just something you don’t think of and if you unhappy with that I am sure there are Mash reruns you would enjoy 😊
PS I am also sure you will leave an open canister of gas in your home while you breath it for hours on end. Did you really think about what you wrote? All I got to say is buy and breath really deep around it 😊
DIY3DTECH.com why would I leave an open canister of gasoline in my house?
Because of your "probably put gasoline in your car on a regular basis" makes no sense. As when I refuel my car I am out doors and using equipment that was purpose designed for exchanging fuel. As if you have not notice modern gas pumps have "fume reducing nozzles" for this very reason. So you wan to carry out an "accurate" analogy, this would be akin to placing a canister of gasoline in your home and allow the the gas to vaporize so you breathe it in like this printer. Common Windex really? Again no comparison if you look at the MSDS sheets, the resin material was not designed for "home" use, it is an industrial compound and not intended to be used in the "home". If you read down the thread you see the comments of regarding this. As open the resin container in my shop which is relatively well ventilated I had a allergic reaction to it which is what sent me quickly the MSDS sheets for the product. Also these folks have also written up similar here: www.fabbaloo.com/blog/2015/11/5/3d-printing-materials-toxicity-assessment-yes-toxic
My only takeaway from this is that you neglected to read the MSDS before using the stuff. This is not a judgement on the material as much as it is a judgement on you.
