Videos like this are a nice break from watching consumer level 3d printers. Industrial 3d printers are interesting because reliability and repeatability requirements are so much higher. Its like the difference between a desktop CNC and an industrial CNC.
I was kinda expecting to see a PLC running things. Then again, I'm sure that those control boards have gone through rigorous testing too or they'd have a tough time selling systems.
PLC is only used as an addon when you have attached automation to the machine but even then it takes care of really primitive tasks (automatic material changes, pallet changes, robot arm loading etc). CNCs in general or 3d printers do not need a PLC, just a dedicated controller board that also has alot of I/O like a PLC and logic behind it.
i thought metal had to be SLM
Nope!
@@davidtobin cool
Today I learned: if you really want to break something just give it to David. :)
Notice how these guys didn't allow Joel to be in a room with unfused sintering powder.
.....yet!
Not something I would see as unusual as handling sintering powder requires personal protective equipment. I don't really see that as a red flag.
@@nerdon2 Sorry, this is in reference to the home desktop SLS printer Joel reviewed a few days ago. He was handling unfused powder in his studio, spilled a bunch all over and all he wore was an N95 covid mask and some rubber gloves which is far from enough. I made this comment to mean "this is how professionals deal with sintering powder: they don't let people just touch it or brush off their demo prints or have any contact with even just the room in which that powder is kept". It's a stark contrast, and a lesson that should have been in his previous video.
@@gownerjones ah yeah that's a fair comment, thanks for the explainer!
I just had a look at micronics about page because I had heard that they were college graduates, it seems there are two college graduates and one professor involved in it.
Their about page does not inspire confidence, especially about safety. They show off how they used to be based in a college apartment before moving into their lab. Their pictures show what looks like a relatively large milling machine covered in metal chips less than a metre from a bed. There is not enough space to safely work and you should not have a milling machine in a bedroom. It also isn’t safe or considerate to install all that equipment in your average apartment either. College apartments are made to be cheap and small, not much else and they typically have thin walls which is bad enough with your average student let alone someone running machinery like that. I doubt that any of that was approved by the college, especially using a relatively large milling machine (by relatively large I mean not just a small desktop one) in a college apartment where typically you may not even be allowed to light candles. Then there is also the concern of all the equipment being too heavy for the floor to hold it which I doubt they took into account since they would need to ask the college or their landlord about that.
If they were using milling machines and building SLS machines in an apartment and their bedrooms likely with not very good ventilation then they just don’t care about safety and that seems to also be the case recommending a face mask and gloves for handling the powder.
Not just that but by running those kinds of machines in an apartment block with almost none of the necessary safety features then they are putting everyone in the apartment block at risk. Sure they have a fire extinguisher right next to the milling machine but it is less than a metre from a very flammable bed in a bedroom, it just isn’t safe. Also I hope the apartment block had separate ventilation for each apartment because if not then their SLS powder likely could have made its way into other apartments.
I would not trust these guys with safety at all as they clearly don’t care about their own safety. I just hope people see sense and don’t run one of these in their house without the proper protective equipment although there will be people who know the risks but still do it. SLS is not ready or safe for home use.
Hello, I have a question, about how much does a 3D printer cost and where can I purchase one?
It is very nice to see science being produced on the ground
This is build like a hobby machine compared to an EOS 😂
I love these videos in which you give us a detailed look at cutting edge 3D printing tech! I'm hoping I'll be able to see everything at Rapid in one day. Do you think that's doable? It's been many years since I've been to the show, so I don't know if it's gotten bigger.
High-5!
I still think the idea of SLS at home is silly.. by the time everything is said and done you end up needing something like this anyway :o
Hello,
Wonderful channel,
I have a question: what is the minimum wall thickness we can make with metal 3D printing ?
Is there a coupon code?
lol Hi adam savage / tested on the monitor in the back.
Glad you caught that! Right when he says "tested"!
god dang it, Rapid TCT is on Tuesday, Wednesday and Thursday aww
i want one of these but there is no way i could ever afford one
TESTED on the monitor there. Lol
Just out of sheer curiosity is it possible to print cast iron with standard cast iron strength im trying to reverse engineer parts for equipment from my 1888 frick sawmill to my 1951 international harvester horse drawn sickle bar mowers
I don't think so. If you really want a cast iron part, using a 3D print to get a casting mold made and actually cast in iron might be more economical. Since the old part was already cast conventionally, it should be easy enough.
@ProtonOne11 yeah in theory but I A don't have the original parts for the friction feed mechanism on the sawmill so I'm starting from historic scans and that was already kind if the plan which is why i bought a creality ender-5 plus, & B unless I cast the parts myself with the furnace a friend in portsmouth built for recycling purposes I have only three other foundrys available to me cattail being the most likely option but they are a 7 hour 49minute drive unless I have ten castings or something large like parts for an AD baker steam tractor it might be more economical to print the one offs at home and keep a plastic master mould on hand incase someone approached me needing a dozen of the part
Doesn't the cast in cast iron refer to it being poured into a mold, i.e. casting? Maybe this is just one of those misleading names, where the process is in the name, but it it just refers to a high carbon iron instead of needing to be cast.
@aperionx good question ,I think it's the material not the action from what I just read, the iron gets it's properties from the carbon being above 2% and silicone above a similar percentage

How do they generate nitrogen
Are all of us such nerds that we have Adam Savage’s Tested playing while we work? I know I do because I want that workshop!
You cannot miss out on that one haha. But definitely the perfect workplace for that.
As an EOS P290 operator, if I open the door, will I feel the heat? It's like stepping into an oven! 😅
OMG youtube!?!!? WTF? I've had to reload this video over 100 times and it keeps getting stuck! Other videos are fine. It's just this one!
Really? Ugh that sucks I’m so sorry. Thanks for sticking through!
@@3DPrintingNerd It was mostly in the middle too. Beginning and end were fine. Very odd. And all other videos are just fine. lol
We're still far from affordable consumer metal 3d printer.
But not as far as we used to be.
TCT, good stuff
I want that ball 🏀
Love seeing the internals of these kinds of machines. Would love to hear a little more technical details, but fun none the less.
Cool Video, Thanks for making it!
It wasnt that long ago where hobby CNC wasnt possible in the home workshop. Or at least it was very uncommon. Now its very affordable for really good machines.
Im hoping these SLS printers will go the same route. We already can do so much in our home workshops with 3D printers, CNC's, lathes etc, having a metal SLS would be the icing on the cake.
Home SLS machines will be a true game changer. I don’t really see the value in nylon ones. Marginally stronger than FDM for 100x the price
@@1SmokedTurkey1 Yeah I tried nylon SLS parts from JLCPCB and there were not as strong as FDM PCCF
6:27 why are you on the screen on the back?😂
that is super cool, thanks Joel
I know a lot of these machines are out of manys price range but in the video or description can you include an approximate price? I don't know about others but I like to follow the progress on technology and cost. This way when I hit the lottery, I can afford one of these machines 😂
You need to realize that you need to purchase more than just the SLS machine, right? The majority of your cost will go into the post processing/safety equipment, as all contact with the powder needs to be completely eliminated. Any powder that you breath in will forever be in your lungs, leading to mesothelioma. During the sintering process, you need an extreme ventilation/filtering system to ensure than none of the vaporized components can be breathed in. You can’t just ventilate this outside, as that is illegal.
This post processing/safety equipment is going to be at least 60% of your total purchase. This is something that has yet to be discussed by @3D Printing Nerd.
im wondering what they think of the new competition that is coming up in the lower ends of the market with Micronics for SLS(plastics) and Metal-Base for SLM (metal)
Micronics is not safe as a home printer which they are trying to market their product as. The printers may be cheap but to use them safely you will need to invest in a lot of other equipment. The SLS powder is very bad to breathe so just wearing a N95 mask is nowhere near enough protection. You need respirators, a dedicated ventilated and sealed off room, proper cleanup procedures, etc. People using it professionally even have to use all anti static equipment like vacuums because there is a chance that powder in the air could explode if there is a spark. Notice here how they didn’t let Joel anywhere near powder or unfinished parts and it looks like the machines have been properly cleaned to show him.
The basic mask and gloves is not enough to protect you from direct exposure but there are other issues with it being a very fine powder, even without spilling it when you remove the print from the machine you kick a lot of that powder into the air where it will remain for a long time and will settle on surfaces where it can be kicked up later, most likely when you aren’t even wearing a mask. This is made worse by the sifting method of the micronics machine, put it in a box and shake it up.
SLS is just not safe for home or hobbyist use at this stage, that should be clear to see when looking at what protective measures companies have in place for using the machines.
Looking at micronics about page they clearly don’t put much thought into safety, they show off how they used to be based out of a college apartment before they moved into their lab and their pictures show what looks like a milling machine covered in metal chips literally less than a metre from a bed. Now they are marketing an SLS printer for home use? I would not trust their safety claims or advice.
I think that from that perspective no 3d printer, fdm, sla or sls should never be used at home. The same can be said about drill presses, milling machines and saw machines. In the end it is also determined by the ammount of exposure

Amazing!
Metal print has real potential and we need the inexpensive plastic printer world to overcome the psychological barrier into metal sintering so we can get super cheap machines because lasers are quite inexpensive, flipping mirrors isn't super costly and pushing powder isn't that complex either. Nor is an inert atmosphere, you burn off the oxygen and keep the chamber small.
With metal printing you can do really serious stuff. You can genuinely print a high performance jet engine. Not just a toy that works poorly but one that competes with million dollar commercial engines. Plastic is fine but metal is where it is at.
The reason why this relatively simple technique isn't more popular on the home market is not because of a psychological barrier. It's because sintering powder, the raw medium used with these printers, is extremely dangerous to even be in the same room as. In industrial settings, SLS printers are placed in underpressurized clean rooms and the people working in them wear clean suits and respirators. You can be the most careful person in the world and keep everything meticulously clean but you'll miss some quantity of powder which will mix with household dust into your air. Over time, your environment will become badly contaminated with powder particulates which you unwittingly breathe in, which deposit in and slice up your lungs. It's asbestos on crack.

What an incredible machine, it makes me even more want to get a micronics to enter the SLS world even though it is very far out of my reach.
These machines are changing the world of technical materials.
Keep making videos like this, a big hug from Temperley, Buenos Aires, Argentina.
Que maquina increible, me da mas ganas de conseguir una micronics para entrar en el mundo SLS aunque este muy lejos de mi alcance.
estas maquinas estan cambiando el mundo de los materiales tecnicos
sigue haciendo videos asi , un abrazo grande desde Temperley,Buenos Aires,Argentina.
Unless you have a proper clean room in your home, the micronics would be a bad idea even if you were rich.
I really dont understand Joel, dont be hanging that phat body on that door. Put those hands in your pocket if they only gonna destroy shit
I still can't afford to go to any of these events on the west coast or in the middle of the US. Unless it's within about 3 hours driving distance I can't afford it.
SLS Printers are still too expensive for me. Even the $3000 Kick starter one.
Gday
guh
Imagine the possibility of one of these printers at home! Metal prints whenever we need it... Heck! We could have metal minis for all of ys hobbyists!
you now that they do not come out like that right? to uncut the part and the supports with metal powder ypu just need some pse and a few machines... that will never happen at home.. trust me.. one sniff of titanium powder fucks you up
The hardest problem to solve is how to make this technology available to many people without those people giving themselves COPD. Sintering powder, especially metallic powder, will absolutely destroy your lungs. Even when you wear masks, even if you wear gloves. Over time, you will waste away your lungs worse than a smoker.
@wildniscamper7276 the powder is the support. Nothing to remove. You blast the extra powder off with compressed air and/or a shaker. You also have to think about inner voids that will trap powder, kinda like a resin printer.
@@wildniscamper7276 as the other commenter mentioned, the powder here is the support and yes I am aware that they do not come like that, but once again hobbyists are in full understanding of this matter, the hobby already requires we put in the elbow grease to get our work to look good, putting in extra work is not a deterrent
@@wildniscamper7276 also, there is already a company that makes a consumer-grade sls machine, well, it's a Kickstarter but the machine already exists, it's not out of the realm of possibilities.
After the fiasco of the at home version, I can see why you wanted to show us a video of SLS at it's best lol.
How was it a fiasco?
@@username9774 Because, as many people pointed out, that nylon powder the printer uses is orders of magnitude more dangerous to breathe in than asbestos and an N95 mask and some rubber gloves are not enough protection for that. Factories like this one put these machines in clean rooms where technicians and operators wear clean suits and respirators while handling the powder. Having a machine like that printing regularly in your home will give you COPD right quick.
@@gownerjonesEven just ABS fumes scares me, and this powder stuff? No thanks.
@@youtubehandlesux If you had the choice of a lifetime of breathing 100% ABS fumes vs 100% unfused sintering powder, which death would be slower? 😂
