This video explains the best and least non-toxic way to clean 3D resin prints using Mean Green, an ultrasonic cleaning vat, a small amount of isopropyl alcohol and water.
The workflow is as follows:
1. Remove prints from build plate
2. Place prints in pickle jar filled with Mean Green. Agitate for 30 to 60 seconds
3. Place prints into ultrasonic cleaner filled with Mean Green heated to 50 Celsius. Run ultrasonic cleaner for 5 minutes
4. Remove prints from ultrasonic cleaner and immediately remove supports
5. Clean prints using spray bottle of 99% isopropyl alcohol and a soft toothbrush for 30 seconds each
6. Place prints in pickle jar filled with water and agitate for 30 to 60 seconds
7. Place prints in container on a paper towel, cover and let air dry for 12 to 24 hours
8. Prints are then ready to cure in UV curing station of your choice

How To Clean 3D Resin Prints - 3D Model Cleaning Workflow Using Mean Green & Ultrasonic Cleaner - วิทยาศาสตร์และเทคโนโลยี
Great video. Best part are all the sound effects you make lol. Juts like Cloudy with a chance of meatballs during science montage. I'll definitely add mean green to my process.
It works really well if you run it in a heated ultrasonic cleaner. Then you just need to hit your prints with just a little squirt of IPA and a toothbrush at the very end. :-)
I watched this video in my wheel chair and it cured my legs, so I can walk again! I've been bedridden for 10 years, thanks 3d Printing Miniatures! Please make more vids so I can cure my COVID next! :D
Awesome video. I love the amount of detail you give. 👍👍👍
Love the sound effects. A+
Thanks for such a brilliant video, I was struggling to get a really good finish on my prints and I've taken on board a lot of your work process and my prints have never been better.
Glad you found the video helpful. The workflow in this video is one that I pieced together after months of trial and error. And, also, from watching hours of other printers' videos on TH-cam. I took the best and most useful parts (for me at least) and incorporated them into my cleaning routine. None of it is set in stone and I encourage people to use or ignore parts of my cleaning process to suit their needs and their setups. Best of luck with all of your prints. Thanks for watching.
Low budget tip: If you don't have a fancy cleaner, you can switch the bath and the toothbrush step. If you scrubb them after the first stage wash, it'll be more messy, but the scrubbing will only need a manual rinse in iso afterwards.
Great video, I like your style! Some people cut videos down to not show any mistakes (like you dropping the mini like 5 times 😂), but the more extended cut type of video is way closer to reality and shows a lot of detailed steps in between. Keep it up!
If I cut out all of the mistakes and dumb parts all of my videos would only be 3 seconds long. 😂
How has Mean Green been holding up? Do you filter the resin out of it every so often or just put it out for hazardous waste pickup every so often? I picked up 2 gallons to try out but haven't done it yet, need to think out all the maintenance/recovery/disposal things I'll be doing... I like the idea of using heat cycle on the ultrasonic (Unfortunately the heater on mine is burned out though), and reduced odors of the Mean Green...
This is a great video especially for us limited on funds and space to work with. I am doing my research before buying a 3D resin printer and your process is very doable. How do you handle your dirty mean green once you have depleted it's cleaning potential, can it be placed in a location where sun light UV cures any resin within the mean green solution and then properly disposed of. Thank you for your time and for sharing your process. Happy printing.
Awesome video and this is super helpful! Going to do almost the same process/setup you have here
I'm a total noob at 3D printing, but have you heard of anyone using Windex as an alternative to Mean Green or IPA? Also you need to further UV cure your prints after removing them from your Mars?
Thanks, that was super helpful! Do you do anything with your printing tank, or does it just sit on the printer all the time and just gets topped off with new resin? What do you do if you want to change resins?
I don't remove the vat unless I have a catastrophic failure that either sticks to the FEP or leaves lots of pieces of failed print floating around in the vat. If I'm running prints using the same resin I'll just top off and print the next batch. If you change resin you have to change your vat and you need to wipe down and clean all sides of your build plate with IPA and some paper towels. Some people buy multiple vats to store different color resins to make switching between them easier. You need to make or buy covers for these vats and make sure not to spill them. I've never done this but it sounds like a cool idea if you're someone who prints a lot of different kinds of resin all of the time. I have a very soft silicone BBQ baster I got at the dollar store that I use to gently swirl around and strain resin through to check my vat for failed pieces and supports between prints. This seems to work well.
Hello. Thanks for this video. Some people seem to use wash and cure and others use sonic cleaners. Are sonic cleaners flat out better?
They both work great when used properly. It’s really just up to personal preference, how much space you have and what you can afford.
will this process work to make sure my prints dont come out with that chalky white residue?
Hi - great video. I was wondering: Is there any residue from the resin left in de ultrasonic cleaner after the cleaning ?
And how long do you cure prints ?
The inside of the cleaning vat is stainless steel, so any residue just settles at the bottom. When you clean the tank out (depending on how often you print) it pours out and you can wipe up any remaining residue or bits with a paper towel.
As far how long to cure prints, I have a video about that on my channel. It depends on what kind of resin you're using, what type of curing station you have, and the models you're printing.
Been looking into an ultra sonic cleaner. But everywhere I’ve read it says using ipa and of mean green inside of one is extremely dangerous? Is that just bad info I’m reading lol
As for the Mean Green solution; do you use straight concentrate out of the gallon bottle, or do you mix it with water?
I was using it straight and undiluted.
hey man trying upgrading to the magnetic plate for your printer. it makes your life soooo much better... best 20 bucks i have ever gotten :)
I've tried a couple. They seem nice but they don't do much for me. I don't like the process of having to remove and remount them between prints. I just try to dial in my base layer times and that seems to work for me. But, to each their own. Happy printing.
Excellent video! I've been using your process outline and my prints are coming out far better than before. Where did you get your tray that you show at 1:40?
The dollar store (i.e. Dollar Tree, 99 Cent Store, etc.). These types of stores always have all kinds of great items you can use for 3d printing and hobby stuff.
Just watching through your video series since I just started 3D printing myself, I think it'll be super helpful. Question though, if one didn't have an ultrasonic cleaner, what would you replace that step with? Or would you say this method requires an ultrasonic cleaner?
It's doable. Some people will use a wash and cure station instead. Or, they'll use 3 separate containers of IPA (not too clean, pretty clean, and very clean) and rinse/dunk their models 1-2-3 in each for 30 to 60 seconds each. I have used this technique and it works quite well.
This vid has been soooo helpful in getting me started on my process.
Question, is it necessary to heat up the ultrasonic cleaner if you've already removed the supports from the model?
Probably not.
hi bro, nice video. What do you have in the ultrasonic cleaner?
I forgot to mention it in the video but it's in the video description. It's straight Mean Green (about 2/3's full in the vat) heated to 50 degrees Celsius. The heating it to 50 C is really what makes the prints come out so clean and helps the support come off so easily.
At the end if you have an air brush you can blow dry or use a quick pull of a dust it can to air dry
Great tip. Thanks.
Do you find that the prints will sometimes start pitting? I’ve found that these tiny holes appear and I’m not sure if it’s due to cavitation erosion from the ultrasonic or some kind of chemical reaction with water
That sounds like you are deploying the ultrasonic for too long. You eventually corrode and break down the actual mini when left for too long.
Hello friend, the information you have given me is incredible, I looked for it for a long time, I really appreciate that you take the time to give us this kind of advice. I tell you that I make 3D prints to make negatives for chocolate bars, it is important that the prints come out very bright, what resin do you recommend that can shine after all the cleaning and curing steps you mention. It is important to mention that when making the silicone copy this 3D piece should not have additional paint to shine because it comes off or makes the silicone not cure or catalyze. On the other hand, I have seen that you have a digital humidity and temperature meter, can you pass me the link of the one you use as well as the mat on which you place the prints?
I'm not sure resin prints are safe to use with food or food products. You should contact the manufacturer of the resins you are using to make sure they are safe to use for your purposes.
Super awesome workflow. What liquid is inside the ultrasonic cleaner? Water, Mean Green, mix of both?
EDIT: ahh, found in comments that it is Mean Green straight
Yep. 👍
Do some tabletop tags! Your video is very useful for that userbase. It's essentially dnd printing x10 the miniatures, so a solid workflow reduces headaches.
Thanks for the suggestion. I appreciate it.
What was inside the sonic cleaner? Was it more Mean Green? Also, you don't cure them?
Sorry. Not sure if I missed it but what's inside the ultrasonic?
I use Mean Green. And swap it out every few weeks when I'm running a lot of prints.
@@3DPrintingMinis Thank you! I will look into it. Mean Green is safe to heat?
Not sure. You'd need to google the manufacturer and contact them to find out for sure. Should be able to email or FB/IG/TW message them and get a response.
What’s in the ultrasonic cleaning container? Water?
It’s Mean Green heated to 50 degrees C. You can also use heated water instead. In that case you can fill a ziplock bag or heavier duty Mylar bag with Mean Green or 99% IPA. Either method works. It’s just personal choice.
Great vid! Very informative :) I was wondering if you could share your workflow re: cleaning out the Ultrasonic Cleaner. Do you just drain all the fluid/resin out of the tank into another container to allow the resin to settle to the bottom before cleaning it out?
The clean out process is pretty simple. If I'm running Mean Green inside of the vat I put the ultra sonic cleaner up on my workbench and drain vat (through the little drain spout on the side) into a large, empty OJ or Apple juice bottle. And then wipe the inside down with clean paper towels. Then spray some 99% IPA in the vat and wipe it down with more clean paper towels. That's it.
Then I take the bottles of old Mean Green to the hazardous waste disposal drop off site in my town and cure the paper towels in the sun on the side of my house before throwing them away.
I've recently switched to filling the cleaner vat with plain tap water and putting my cleaning Mean Green into large, sealable mason jars. Then I only need to clean out the jars every so often. And the water in the ultra sonic vat I can just dump down the sink because there aren't any chemicals or resin in it. I'll try to make a video of this new process I'm using soon.
Thanks for watching. I appreciate it.
Do your prints smell of mean green by using this because its really strong for me.
Not after I wash them in water and cure them. I think the smell of the resin itself is more pervasive than the Mean Green smell. But that's just my opinion.
ive seen people mention and i havent even ordered my ultrasonic cleaner yet.. but people put the item in a sandwich bag or something sealed full with IPA and drop that into the Ultrasonic cleaner filled with water and it keeps all the resin out of the ultrasonic.. have you ever tried that? how often do you clean out your tank?
I've seen people discuss this method as well. It seems to work really with when using IPA (i.e. 99% alcohol). The reason being that you don't want to heat up a vat of IPA to 50 C/120 F because, well, danger/fire/explosions/etc. :-)
Also, IPA is kind of expensive so using a bag of it makes it last longer and wastes less. Instead of a plastic bag I've seen people use a metallic mylar bag to hold their IPA as well.
I went with Mean Green because it's less expensive, less flammable and doesn't smell as bad. Also, I can leave the Mean Green in the ultrasonic cleaner vat for months (as long as it's covered) and nothing much seems to happen with it. I've been using the current Mean Green vat for over 2 months (and dozens of plates of prints) and I'm still getting really good results from it.
I'm a little iffy on heating up a bag of IPA (even if it's in water) on a workbench inside my garage. Seems like too much potential for an accident. But, yes, people definitely do it and many seem to really like using the method.
What is in your ultrasonic cleaner? Water/mean green?
He uses full concentration mean green super strength. They have other versions, but mean green is the biodegradable stuff that is hand safe. (May not be safe if it has resin in it.)
I thought that red lid had UV protection?
it does but the sun just blares into our garage 1/2 of the day when we're coming in and out, so I just do it for an extra bit of peace of mind.
whoever gave this video a thumbs down is a complete ding dong. Great video!
I appreciate the kind words. Thank you very much! 😀
What's the purpose of the merry-go-round music?
To lure merry-go-round enthusiasts to my channel and to get them to watch/share my videos. They're a highly sought after demographic for Google's advertisers. 🤷♂️
@@3DPrintingMinis I hope you start a radio station on the side, I'd totally sign up to listen! :D
could i use a salad spinner?
No, but if you do please film it and share it online. Thanks. 😂
Should probably not reuse the nitrile gloves too long - the resin will penetrate it over time
i hope you cure the resin on the paper towels first before you dispose of them. Also i would cure the resin sticking on the cloves as the residu keeps building up, as the gloves probably lay in the sunlight or smt its curing aswell but still i would be rather sure thats it cured.
I have an entire video on that. 🤷♂️
You might have a video, but if you don’t mention it in this video how would one ever know? Don’t assume that everyone knows all your content. I’ve been printing since 2014 and have never seen a video of yours before this that I’m aware of. To me, it looks like you’re being reckless with your handling of highly toxic materials. I’m glad to hear that you are careful and will look for more of your content. Thanks for sharing!
Great video, but the music is too loud. I can barely understand what you're saying over the music
It's has to be loud or else you'll hear the wails/moans of my tied up victims in my torture dungeon/3D printing hobby studio. I'm not rich. I can't afford two separate areas for these activities. 🤷♂️
@@3DPrintingMinis You should become rich and afford at least 3 different areas, more music! more noise! more victims! Yay! :D
nice vid but maybe consider lowering the volume of the music. it drowned you out in a few spots and was really annoying
I have two passions in life - 3D printing and classical music. Both wage a continuous, brutal battle for control of my heart and soul. Sometimes, the music wins out over its adversary. The audio in this video is a stark testament to this fact.
Also, thanks for the feedback. Eventually I'll be getting a lav mic for these videos. Hopefully that will help.
Mean green? Huh 🤔
Yes, as opposed to filling up a heated ultra sonic cleaner with 99% and most likely burning down my garage. 😂
