Resin 3D Printing - Ultra Sonic Cleaner Safety Warning
HTML-код
- Опубликовано: 17 сен 2024
- I had a major issue with the heater within my new large Ultra Sonic Cleaner. Please make sure to check and see if your heater automatically shuts down when not actively in use.
Technology can be fun but please be safe and take the proper precautions when working with any of this technology.
Thanks for watching!

Here is a tip. I have multiple ultrasonic cleaner's and what I've learned is to place my parts whether it's resin 3-D parts, motor sport carburetor type parts, or firearm parts and there specific cleaning solutions into either a stainless steel or plastic container. The container is then put into the ultrasonic cleaner that has water in the tank. The water will transfer the frequencies directly to the solutions in the isolating container. After you're done cleaning the containers are easy to clean and or store. I've even used red plastic cups. Oh and you can use several smaller containers with different solutions at the same time. By the way make sure the level of the cleaning solution with the parts is just a little higher than the water level in ultrasonic cleaner.
This is what I do. Saves on a lot of cleaning solution and also you are dealing with smaller quantities of resin contaminated fluids. "Going back to the bucket method." jeesh. throwing the baby out with the bath water.
Best way to use one of these is to always put your part in a secondary container with your cleaning solution and then place that in a bath of water. You can then use IPA this way.
I just bought one for 50% off because the heater component didn't work. Saved me the time of disabling it and I got an awesome deal. Thanks for the video!
Is there a way to disable the heater on the standard units? For example by disconnecting a cable, without preventing the cleaner part to actually run?
Hey Jesse! Have run into this before because it's so easy to leave your cleaner on when you're getting ready to cure a print-- a good way of avoiding this in the future is to have something like a lamp wired up on the same power strip as the cleaner so that if the lamp is on, the cleaner is too.
You can then use the power strip as your cleaner's power switch and if you see the lamp on before you leave, you've messed up :)
Thanks for the PSA. Next video: how to disable the heater on your ultrasonic cleaner?
Turn it down below room temp.
@@chrishamlet3470 on the series as shown in this clip you have to turn it on after powering. AND each cleaning cycle if you don't it stays off.
The heater shouldn't be on by default. And once you turn it off it doesn't go back on, even when you turn it off and back on. And most ppl by now know to use bags of chemicals, I use IKEA -double zippers inside normal water 6L
Francis Arthur To be fair I use mine for multiple jobs but I’m extra careful with IPA that I don’t put the heater on, and with detergent I always have to reset the heater when I switch it on. Mine always defaults to off after powering off. After having a major house fire caused by an FDM printer setting on fire when in standby maybe I’m just a bit more cautious 👍
@@chrishamlet3470 The method I use, couldn't that work for you?
I fill mine with 5.5 liter water and using a thick IKEA bag with double zip-lock with IPA.
I put the UV resin object in the bag and leave it to hang in there with the flap underneath the lid.
So you can do a long time with the same water and it can save a huge amount of chemicals and you don't have to clean and empty the machine all the time if you put something else in there. Just a new bag.
Thanks for the info. One solution might be to connect the power cord to a switch and only turn it on when needed, rather than letting the unit have continual power and the heater be on.
I'm always extra nervous about my printer and Ultrasonic. After I take my prints off the build plate, unless I'm IMMEDIATELY printing something else, I turn off the power on the printer.
When I take my parts out of the ultrasonic, I turn off the power because I don't want the LED display or other indicator lights to burn out prematurely.
Shut the machines down before leaving the room, and it's all good. Thanks for making these videos! Uncle Jessey's recommendations were what set me over the edge to buying an SLA resin printer, and I don't regret my decision!
The manual for mine says not to leave it plugged in while not in use. Probably for this reason.
yeah mine (smaller) indicates you can use ipa but to NOT use the heater function, let thee machine rest 15 m in between cleanings and to clean/empty when not in use. which makes the method derived by nasa t essentially sous vide the parts your cleaning for ease of use and cleanup ala bag of ipa in a water bath.
I think if he had read the instructions he could have avoided that, I have one of the same brand and the instructions say the same as yours
Yep it's a no brainier even if you haven't read the manual, so I'm not Shure what he was playing at, R.T.F.M
So I bought this ultrasonic cleaner after watching this so what I do is turn the heating element below the default setting. I have the ultrasonic cleaner on a power strip so I just turn it off after each cleaning session. So props for this video because it spurred the idea to put the cleaner on a switch.
So, I have the same Ultrasonic Cleaner that you have and it stays plugged in. The power switch is not flipped on unless it is in use. For the heater to be on, you must set the temp and push the "On/Off" button and the heater comes on with an indicator light just to the right of the digital display (on the left) showing it is either on or off. It sounds like you had the heater enabled, ran the ultrasonic function for some prints and forgot to turn off the heater. Getting used to new pieces of equipment is part of the process and I have enjoyed your videos and reviews, but; this video should be more orientated towards "Don't forget to turn the heater off".
You got extremely lucky. There is a warning that comes with all heated ultrasonic cleaners:
MAKE SURE THERE IS LIQUID IN THE CLEANER WHENEVER POWER IS APPLIED
The ultrasonic transducers will literally burn up if they are turned on w/o liquid in the tank. The heater is located on one side of the tank, and the thermistor is located on another side of the tank. If there isn’t enough liquid in the tank, the heating element will stay on indefinitely. The cleaning solution will be exposed to extreme temperatures, which can create toxic fumes/cloud, which is what happened to you. Normally it won’t catch fire, but it could.
Aah, that makes sense! I was wondering that isn't there a thermostat shutting the heater off, but of course it won't work if the liquid was too low.
Glad to hear you caught it in time, and that no one was adversely effected.
Always, safety first and know your gear, right?
I'm trying to set up my ultra sonic for resin cleaning and am more than happy to get some of these tips
FYI, I got the Mean Green cleaner based on Uncle Jessy's cleaner test, and I found it less effective than IPA. My first few resin prints didn't seem to cure quite right, and I thought it was my UV light. So I got a new one, and the prints were still sticky. So I tried cleaning with IPA and the same UV light, and I got solid prints. Don't know why my experience differed.
I've had the same. I just use the green cleaner to get rid of most of the junk, then use IPA to fine-clean the rest.
@@PokketGM you know. a prerinse in green before IPA is a good idea! will extend the lifespan of the IPA as well!!
i also sadly found it less effective than IPA which is sad because its HALF the price of IPA :-(
@@nerys71 what concentration of IPA are you using?
I have been wanting to see a test of the different concentrations of IPA to see if some of the higher concentrations (91% or 99%) work to clean the resin faster and if they have any ill effects on the prints.
I usually have tons of 99% around for use with electronics.
@@xandersnyder7214 i use 91% the 70% did not seem to work as well i may try it again with the wash station as it is quite a lot cheaper.
Thank you for posting about this. I just bought the 6L version of this cleaner. I may just put the plug on a timer as a backup or open it up and just disable the heater completely. They should have had timers for both elements of the cleaner, but these are cheap, so we get what we pay for.
if you do want to save this one you could use a smart plug to set cleaning programs with a timer, from your phone. it'll cut the power completely when its done.
Oh wow. I will have to look into that for sure now. Didn’t realize you could set a timer on some of these “smart” plugs
@@UncleJessy yeah there are some really cool ones now, and they don't cost much! they'll also track your power consumption over a day/week/month/year and a bunch of other interesting stuff. i think some can cut the power when you go below a user defined power draw for example, because it's all being monitored, so you can have them turn off your printers when nozzle and hotbed aren't on anymore (i.e. at the end of a print)
seems like an easy fix for this, and they're generally pretty cool. it'd be a shame to throw out the ultrasonic cleaner if you dont need to. :-)
@@UncleJessy Make sure it's a smart plug that will work with inductive devices. I don't think your regular ole light smart switch will work.
@@UncleJessy how long are you running? I have never had to go more than 10 minutes so I got one of those bathroom timer switches. I got one for my addon heat bed for my mega zero going to use another for my ultra sonics.
press on get things going them tap the button for how much time you need. B07SDBZR5X on amazon is what I have. 1-5-10-15-20-30 minutes. tap and walk away. when the time is up power is cut.
my ultra also only turns on the heat if i tell it to turn on the heat. yours is always on ? open it up and cut and cap power leads to the heating element. the ultra sonics in most cases are more than enough to heat it up. in fact I have to run my cleaning in cycle times because the ultra alone will over temp the liquid (don't want to pass the tg temp of the resin parts) though this may not be an issue with a vat that large!!
YOU MAY however want to start from scratch. I just got the anycubic wash and cure station. I am never going back. it works so insanely well its truly amazing (I have NOT tried it with alternative cleaners yet though !!!) my parts are squeaky clean in 6 minutes flat!! I mean absolutely no tackyness at all. perfect. it works like a washing machine. magnetic spinner gets the alcohol bath rotating vigorously!! very impressive.
if I ever managed to get my mits on a larger resin printer I will build a larger version of something like this.
@@stevelaminack1516 if you hear it click when it switches then its using a relay and that can switch anything within its load rating.
Darn! Thank you for the PSA! I am glad nothing serious happened
Thanks for the video! One note, you don't need the heating when cleaning resin. The heating is more for cleaning metals like jewelry and things like that. For resin, you're good without the heat. As for the heating element, not sure about yours but mine actually has an On button which I never use. Keep safe and good this was brought to everybody's attention. Thanks again!!!
Yeah, I don’t recall turning on the heat but I must have. I haven’t plugged this one back in yet. Letting it sit in my garage for a few more days before I touch it again
@@UncleJessy I'd check that yours even has an on/off for the heating element. It looks like the same make as mine, which does not have that kind of on/off.
The heated ones that automatically turn the heat off when the ultrasonic timer ends are safe in my experience. I have one that works like that and one where the heater is independent. The independently controlled heater is annoying because you need to shut it off by hand and if you forget...
thank you for reminding. i will never leave it plugged in.
Maybe you don't enjoy making them, but we super appreciate it. Sharing information has been a keep element of the cosplay and 3D printing communities, and sharing important safety information is vital to ensure the health and safety of all us hobbyists. Thanks!
Dang. I just got my 15L version today. So happy i found this video. Will be getting a smart plug for sure and just rarely using the heat function.
Smart plug, great idea!
Thankfully, I already read over the manual and noticed how quickly the heat can ramp up from it. So I leave the window open whilst in use and unplug it once I'm done.
Good warning. Many units are designed to be able to pre-heat. If I can add two points (as a manufacturer and distributor of ultrasonic washers, up to ones that clean truck engine blocks, plus a 3D printer myself),
1) Please don't use flammable or combustable solutions with an ultrasonic. They typically are not rated for this.
2) Even running the sonics can raise the temperature. If you're only doing short (say, 5 minute) bursts, it's likely not a big deal. But long runs can create heat. You're putting energy into the fluid with the sonics.
And get a cover! Evaporation happens fast.
Thanks for the update Jessy! Stay safe!
Glad to hear and wish you all well.
Thanks for sharing too!!
Feature not a bug. It takes a hour and a half for the water to get from room temp to 45 degrees, and most people want to do several batches once they're up to temperature, so the heater stays on because it can't assume you're done with it once the first cycle is done. It's on you to check the control panel and turn the heater off when you've completely finished with it.
Just unplug it every time! If that's inconvenient, give it it's own surge protector with an obvious light or more convenient plugin location. No need to lose the use of such a great tool.
If you are really paranoid, then cut (and electrically cover) the wire to the heater coil.
When you say the "power was on" Do you mean the switch in the back was on? If you turn the switch off in the back, shouldnt that cut the power to the unit of all its capabilities? Do you really have to "un=plug" it?
@UncleJessy Thanks for the Video on warning us, but you should mention this on your "Testing Resin 3D Printing Cleaning Alternatives" video. I am happy I watched both of them in one day, before going ahead and buying an ultrasonic cleaner for my small prints..
Thanks for the warning and glad you noticed this problem before you or your family was affected by it.
they do have a thermal fuse that cuts the power to the heating element if its overheats. But for that to trip it has to get even hotter then this one had.
You forgot to turn off the heat, so don't blame the machine.
Which can't be done without removing power to the entire machine...
But yeah, he already stated it's user error.
@@PokketGM You're wrong, you can leave it plugged in and turned ON, just turn off the heating in front panel.
Dude..... Thankful everyone is ok... Glad y'all safe.... Thanks for the heads up
Yikes! Thank you so much for letting us know about that. And yeah, I’m sure that wasn’t good for you guys. Hope you’re ok.
Pretty sure the manual says not to leave it plugged in when not in use.
correct
Uncle j thank you so much hadn't even thought of that with the cleaners:)
Thanks for the warning. I do use a shut off timer on mine.
same here ; simple way to be saver.
Thanks very much for the PSA, glad you and your family are ok. I think I'll stick to shaking my prints in containers.
I've seen some people just using water in the machine, but putting their cleaning solution and the print in either a ziploc bag, or a small container, and putting that in the machine. At least that way, you only have water to worry about heating up, but your part still gets cleaned in your solution.
And the dirt also stays in the bag .
Thanks for the video! Glad you're all safe!
Holy crap dude. Glad you all are safe. That’s scary.
thank God you are all safe 🌹
I'm pretty sure the alcohol would have boiled off before it caught on fire. Good to know about the heating element.
iso won't combust until 399°C (750.2°F) so yeah, it's fine in an ultrasonic cleaner even heated for ages
Solid video idea considering I'm just getting into resin printing. Thank you for uploading! :D
I made this mistake once and came in to it boiling over .... Turned it off, cleaned up the mess and it still works fine luckily ... That being said , I've always left it plugged in.
Hi there, I have to respond to this as I'm using exactly the same Ultrasonic Cleaner at work and you can freely leave it plugged in and leave the main switch (in the back) ON as long as you don't leave separate button for heating ON (in front).
the sonic cleaner i bought comes with the warning printed in large letters not to leave plugged in when not in use, as well. this is why people shouldnt make bathtub gin with their sonic cleaners, fogs your judgement....thats my PSA!
Did he leave the heating function on by accident? Or was it off and it just burned up like that?
Grab a heavy duty lamp timer, rated for the amperage of the cleaner, to use as an external automatic kill switch if you plan on leaving the cleaner unattended.
Open the casing and disable the heating element. it should be easy to find as it will be attached to the base of the tank, if you are lucky it will be a simple plug if not follow the wires to board where it can be removed via soldering iron.
make sure you unplug/ disconnect BOTH wires or else you still end up with a part live wire / heating element if it touches ground/ the case.
thank you for the warning. i now unplug mine after each use. i love safe, effective cleaning with Mean Green in an ultrasonic too much to ever go back to noxious, dangerous, expensive IPA in a bucket. honestly i don't care that it takes 10 min in a heated ultrasonic instead of 2 min with an IPA bucket. the results are just as good and there's no stinky flammable smell.
So did you actually turn on the heating portion and forget to turn it off (there are separate controls for ultrasonic and heater)? Or are you saying that the heater turned itself on?
And a follow up, did you turn off with the switch on the back or were the LEDs still illuminated on the front?
@@Aerospacesmith He did neither. Whilst the unit is plugged in, the heating element is on. The heating side of it has no on/off button. You can only control the initial temperature of the heating element (which will increase overtime anyway, due to the electronics inside). Only solution; unplug it whilst not in use.
@@PokketGM the heater does have its own on/off button. If it's turning itself on or the heater is always on when plugged in and bypassing the electrical cutoff switch on the back, then he has a defective unit and needs to get it replaced.
Thanks so much for this PSA. Love your videos.
Bro, that is scary and happens to be something we all needed to know. There are always things to be cautious about when doing these hobbies. Thank you for sharing bro!
I really feel bad for you man but I am glad that you and your family are ok.
thank goodness. all of you are ok. stay safe.
Great warning! I had the very same issue with my cheap ultrasonic cleaner about a month ago so I'm very familiar with that pungent smell of Mean Green.
Thanks for the info, have been looking at ultrasonics for cleaning prints. Will buy one without the heat option.
you wanna get drunk? take a shot for every time he says "again"
🥃🥃🥃🥃🥃🥃🥃
I have that model's little sibling. I try to unplug it when I'm not using it but sometimes I forget. I'll be extra sure I do now, thank you!
Mine just arrived today, the first thing I checked was if it remembers no active heating setting. When I power off and on again. Fortunately it remembers the setting. I'll use a zip seal bag or glass jar with my Ethanol and model for my cleaning cycles.
I got the smaller 3L one. I wanted to know if the heater turn off after the timer. After getting mix answers on Amazon, mostly people saying yes. After trying it for myself, I can confirm that it does NOT *NOT* turn off by itself after the timer expires. Anyone using this while away should purchase a outlet timer or smart outlet.
Thats why you never ever leave any kind of machine fully unattended.
Always keep an eye on your machines, doesn't matter if it's a printer, a cleaner, a cnc machine or whatever. Just don't!
Use a timer switch for that thing so it will turn off after 15 min of use.
heating up the tank from cold can take hours (3 for mine) so its relative easy to forget. It does have overheat protection like thermal fuses but they only fail after the tank becomes dry and that can take weeks depending on what you use for cleaning. A mains timer that switches off in the evening is a simple way to avoid this.
Uncle Jessy, thank you for all you do. I use mean green based upon your recommendation. I however, don't use it directly in the cleaner. I have a plastic container I fill with mean green, then sit it in the ultrasonic cleaner filled with water. The ultrasonic functions through the water, plastic and mean green to clean the resin off my models. But the ultrasonic cleaner only ever has water. This makes it easier to clean as well since all the goop is contained in the mean green in the plastic bin. I never use the heater function. If your heater was running while turned off but plugged in, that sounds like a serious defect.
No, you just can't turn the heating element off. There is no on/off for it. If it's plugged in, it's being heated.
@@PokketGM That's crazy. I guess you have to unplug it after you are done using.
I purchased this after watching your video about it. Haven't used it yet though
What did you have the heat set to? The sun? For it to boil off all the liquid in the green cleaner over night must of had it on 80C. I run mine at 40C and never have this problem even weeks at a time. Don't blame the unit for user error.
A few things for you;
1) He specifically says he isn't blaming the machine. He knows it's user error.
2) It doesnt matter what temperature you start the heating at, over time, the temperature will dramatically ramp up as the electronics inside heat up. It can easily get to ridiculous temperatures if left on too long.
@@PokketGM there is a timer limit on how long the ultrasonic part works and the increase in temperature is not THAT much (10 c is the highest i say on mine) this is the result of a relative high heat (relative to the boiling point of the used chemicals) for a long time.
I love all the know it all posts here that just reiterate what the actual video was about.
He knows to remove power to the heater. He knows it was user error. He knows the heater stays on.
That’s what the video was about.
I had this exact problem. I'm glad it wasn't just me. Left it plugged in for over a month in my garage before i noticed. It bricked the cleaner.
likely just the thermal fuse; look for a round thing size of a coin or smaller stuck to the tank or heating element with 2 wires connected to it. Remove those 2 wires to measure if the 2 connections still have a short between them (it should have) if its open then change it with a new one and likely the cleaner will work again.
You said in the beginning ( at 00:24 ) was "Well, one of the components of this resin 3D printer..." I think you meant the ultrasonic cleaner. Just checking.
Have you tried opening up the bottom of it to see if you can maybe just unplug the heater element/remove the heater rod so that it doesn't function anymore??
Way out of date but should be easy enough to disconnect the heating component from the power? Take it apart, snip off the wires to the element and tape them back up/attach to a terminal block?
Good PSA, thanks for the heads up
Missing temperature cutoff and missing temperature controller. You should always take apart cheapo heater systems to make sure there is a temperature cutoff and that the thermostat exists. If that was IPA you'd be looking at a vapor explosion. Even if it is just the ultrasonic function a temperature cutoff on the system to stop short circuits in the transducers from heating up the bath is still a must.
Jessy. Com on man you have to be careful you're one of my favorite RUclipsrs glad this didn't make you guys sick though much love to you and your family 🙏🙏 great job with the videos
How long did you have it on for? It’s stainless steel, of course it’s easy to clean. Glad you did this vid because I have a new Ultrasonic cleaner for cleaning circuit boards and will check to see if the heater turns off as well or have to have a wall timer
Even 3000 euro cleaners haven't got a thermal shutdown, if you leave the cleaner turned on it will just keep on heating.
they do in the form of thermal fuses but that is only to prevent fires ect . This is just user error and if you are worried use a external mains timer.
@@cmulder002 believe me we have one at work and that one didn't have a fuse. The thermal padding burnt it self. Maybe some will have a fuse but most do not. It wil always be a user error, so was the case at my work.
@@Parasite98 the fuses looks like www.marbeck.com/international-dryer-thermal-fuse-generic-40113801/ ; most are mounted straight on the tank without the bracket though. Think the biggest problem is that industrial tools are being sold to untrained consumers who assume they are as simple and save a s a refrigerator. Btw the fuses are there to prevent fires not to avoid boiling off whatever is in the tank. Besides the fumes there does not appear to have been a safety hazard in the clip shown here.
I have been looking for a better ultrasonic cleaner than the harbor freight one that someone bought me for Christmas one year. I think I found one I like but the good one are expensive so I've been hesitant to buy one.
Anyways... I researching one I thought of the looking at the immersible type. It's where you take the transducer and place it in any take you want. If you are looking for a large volume ultrasonic cleaner I'd think that the immersible types would be best. Only downside of them is they are a lot more expensive, so I naturally filed that option under the list of things I'd buy if I would ever win the lottery.🥴
You know if you can salvage the tank on that unit you have you could probably use it with a immersible ultrasonic cleaner. That is is you could afford one of those.
Trail and error...don’t give up uncle jessy...
P.s still waiting on the transform vs phenom video😭 💔
I have a smaller one that I use. I don’t use the heating function anymore though. But I unplug it every time when I’m done with it.
Thanks for the heads up.
you can use mean green to clean prints? i wasn't aware of that. do you use it for the wash or rinse step or can you use it for either?
whoa, thanks for the heads up
I have a smaller ultrasonic cleaner that has a really really similar front panel... thankfully its heater doesn't seem to run unless you hit the power button under the heater section on the panel
same as mine and also the heater switches off after the cleaning cycle has completed.
Heck dont toss it. To many folks woild love it. Even if it needs a rebuild.
Wow. Thanks for the warning on that! I have one and don't keep it plugged in, but I didn't know the heat stayed on.
is an ultrasonic cleaner better than a curing and wash station? im looking to get into 3d printing and not sure which one i should get
Have you considered opening it and disconnecting the heating element?
you can mod it and put the heater element on a switch...
You know you have to turn the heater off?
That's just it, you can't turn the heater off. The heating element remains on AT ALL TIMES whilst it's plugged in. Even if you adjust the temperature setting...
@@PokketGM So you turn the temperature to 0 so it won't heat.
You might wanna invest in one of those timers you plug into the wall, that you then set up to cut the power after a specific amount of time...... I've been thinking of buying one to set all of my different chargers on one single outlet and when I want to charge a random battery I put the timer on like 2h and after that all of the chargers gets cut off of power at the same time.
Is a ultrasonic cleaner save for IPA if you disconnect the heater
You may have not wanted to make this video but it was necessary for us to know! Thanks!!
Hey Jessy I have a transform and I have been running into some issue with translucent resins and prints failing when trying to print bigger than 30mm. I have run exposure tests and 80sec base and 12sec normal layer have been successful in smaller prints. My current lift speed is set at 150 and I am using chitubox with heavy supports. When printing larger it's about 60/40 failed build plate adhesion and support failure. I angel the prints and still nothing. Do you have any advice on this. Resins I am using are the anycubic green and elegoo red.
You need to put it on a timmer, shut it off when done.
what sollution have you had best results with for cleaning your prints, my first printer due here in a week and i ordered a ultrasonic cleaner as well
Thank you for making this video and treating it with the seriousness it deserves. I'm very glad you didnt have IPA in that thing.
THANK YOU!!
Well, its not like when power up this ultrasonic cleaner then it heat up water to set temperature, and hold it all the time, even if ultrasounds is off?... You know, like Coffee Express with heating bed for hold temperature?...
Just a heads up at 26 seconds into the video you called your ultrasonic cleaner a 3D printer.
The guy is clearly an idiot for several reasons.
It has a heater on/off switch on the front ! This was absolutely user error
