Love these experimental ideas. A boiling hot sponge left on on my screen for about 5 to 10 minutes to soften and remove resin has always been my go to. Even with a full screen leak that's cured it will remove it all without issue in about 20 mins. The cured resin peels off easily, with a fingernail or plastic scraper.

That's actually genius. I believe that any heating up should help a lot, because of thermal expansion of screen vs resin - forces can be huge is rate of expansion is different, leading to ungluing resing from screen. I wonder if ouring way more resin on screen and curing it should also help. I mean a lot more: so that is would not crack but be removed in one piece. So maybe even with use of some cloth dipped in resin that should keep the resin in place.

In terms of screen protection, I use clear sticky back book protector film. Its insanely cheap, 25cm x 3m only costs around $5 and with it being made for books, its thin, clear, sticks on the screen and fairly easily peels off if you need to remove it. Sometimes glue is left behind, but IPA gets that off no problem. You can just cut it to size with scissors and away you go. Only downside is it doesn't protect against impact damage

Hot water and a sponge is the greatest, safest way I have found to remove cured resin. 10 minutes under the hot sponge, and an old credit card to scrape it off

Thank you so much I literally cannot find any other videos or references online about how to clean these screens

I recently had to order a new screen for my Photon Mono X because I was dumb and took an actual metal razor to the screen and scratched some holes in the film. Wish I had seen this sooner, and I also really appreciate you doing the science for others so that we don't have to!

Informative! Thank you for your service and sacrificing some screens for science :)

Thank you! I'm still new and would have been gullible enough to try this. :)

we have found after many times having this happen that using Tub-O towels cleaning wipes. fold it to screen size and leave it on the screen overnight. we use the build plate as a weight to hold it. after sitting overnight any cured resin that was on the screen can easily be scraped away with a plastic razor blade.

Thanks for trying these kinds of things out for us. Sometimes replacing the LCD screen on the Saturn requires a firmware update since there are different firmware versions for each screen, and the replacement LCD might not match the original LCD version.

As someone having his first issue with resin on my screen, thank you very much for testing this out before I jumped on this "fix" lol

thanks for testing for us

You don't need a plastic scrapper, at least for the Elegoo Mars 2 stock screen. I use a sharp metal one, and it can look scary, but as long as it's lying flat and the screen is soaked with alcohol, it will take out the resin effortless with absolutely no damage. The glass is hard enough to resist it. Even if there were microscopic scratches that I can't see and may build up in the long term, you will probably replace the screen long before it affects your prints, as the screen will eventually be damaged by the UV light no matter what.

Watched some of your videos but this one made me subscribe. I'm new to Resin and got resin on my screen so this is helpful and your other video on IPA to clean it off. Also like your Harbor Freight videos.

I have heard people suggest using alcohol based gel hand sanitiser to break down cured resin on screens as it stays where you put it and can be left for some time to allow it to break down the resin a bit before manually scraping/cleaning the screen.

Interesting regarding the glues! Glad to see it KINDA worked with the Gorilla, but you would definitely need to get a good bond between the materials!

Those plastic razor blades are so useful. I have one at every printer!

I had that happen to me early on in my 3D printing journey. All of my resin printers now have a screen protector. Keep in mind that some resin 3D printers have the UV filter on top of the glass and "scrapping" at the stuck on resin will more than likely remove the filter as well. Just take the L, learn from the tragedy and order a new screen. As always Jessy you are a freaking boss, thank you!

love the mars 3

Not sure if this has been mentioned, but I use clear packing tape to clean dried resin off my screen. Clean up and liquid resin still in the screen, run a vat clean cycle, clean again with IPA and tissue then apply the tape and pull. It’s like waxing a hair leg, only less painful and more soothing.

Thank you 🙏

Thanks for taking one for "the team" and science!! 😁

I’d love to know if the glue became brittle after curing longer. So many ideas running through my head now. Thank you for posting this so others can “hopefully” see it and not ruin their printer.

I agree thanks for trying it out definitely stick with elbow grease

There are simple wood glues on water basis and there are express wood glues with solvents. Perhaps these solvents, or a very specific one, are actually doing something against the resin. Also if have water resistant wood glue, that's also speciality that might make a difference.

You should do a resin printer tier list!! Would be amazing to know your list!

Yeah just finished the vid.. I was skeptical too. I'll stick with IPA and the plastic razor blades. Great experiment!!

One way ive used to clean off resin that has worked no problems. Get a sponge set it on the lcd then pour a small amount of hot water into the sponge let it sit 5-10 minutes pick up the sponge an use your plastic scrapper to easily remove the resin. You dont need alot of water just enough to wet the sponge.

i read the title, i had to come! this is mind blowing!

putting fresh resin on the cured resin softens the cured resin and makes it easier to remove

Titebond II is excellent for cleaning vinyl records. The glue is PVA whereas the records (NOT 78s) are PVC. They are chemically similar to the point that they won't bond to each other. Spread a thin layer of Titebond on your record, getting it into the grooves. Let dry and peel it like a face mask. It'll remove dust, lint, dirt, grease, mold, etc. Great for restoring your vinyl back to a pristine condition (just be sure to rinse the record off with distilled water to eliminate the static charge.)

Hi, my always working go-to when the fep film breaks, is: Aceton. I soak a paper towel with simple aceton, keep it wet on the Spot of cured resin. then it gets soft after approx 10-15min and will easily peel. a plastic spatula is a must.

Another thing you can use to clean the dry resin screen is N-Propanol, that does stink a lot, but it is very effective, it evaporates quickly, it does not leave any residue.

The matrix test cards are amazing for scrapping bits of cured resin off the screen! I couldn't find anything soft but strong enough then had a couple of non cured test cards laying in front of me they worked just like the plastic razors and a tad of water like a drop and I mean a droplet then scrape it's cot a burst fep resin completely off my screen with no damage to the screen Protector well impressed lol

What worked for me was just using the plastic spatula + a bit of IPA. Make a small puddle of IPA on the screen, then when its still on there use the plastic scraper/spatula thing to scrape off the resin. Worked wonders.

To remove cured resin from LCD you can use remover for cured cyanoacrylate adhesive, wait about 30 secs, a wipe it with alco

So i have 2 week old Saturn S and of course got a hole in the FEP and resin on the screen on like Day 2. I used the 99% IPA/microfiber towel method and it really kinda ruined the polarized film. Was this the method to use BEFORE Elegoo started adding polarization? Now it seems the best way is extremely hot water on a sponge and then the plastic scraper.

the level of anxiety i experienced while I watched this was over 9000 lmao!

I have found for an added level of protection when using the plastic razors, I file/sand the corners of the blade into a curve. This way if I am an idiot and stab the FEP or screen with the outside edge of the blade, no harm.

Well, I won't be trying that. Thanks for the demo.

If you hadn't made this video, I probably would have tried it. I use a very similar method to remove dried acrylic paint from my palett - with excellent results. So, I would have been hoping that it would work the same. I am wondering of the original version that you saw was with a water washable resin?

Great video . You have please make a video how to update these machine

Wood worker here, eventually the glues will harden up and become significantly more brittle. While the will have a certain amount of mechanical give, depending on brand they will all become significantly more crunchy as they lose more moisture and polymerization continues. Would a coating of PTFE spray on the screen last long enough to prevent adhesion if some resin tries to cure on it? While I have a screen protector, a spray of PTFE would have better light transmission properties I would think. I was also thinking of a coat of paste wax on the screen and the top of the build plate to assist in resin rolling off may be useful.

@JeffroDH

The problem with the "Teflon" sprays is that they are simply light carrier oil with tiny particles of PTFE. The PTFE doesn't dissolve into the solution as far as I know.

When I got a resin leak that went UNDER the LCD and adhered it onto the piece of plexiglass that goes under it, I put the LCD with the plexi in the resin vat, filled it with IPA and put it on the buildplate of my FDM printer set to 60 degrees Celsius. It did separate, with almost all the resin staying on the plexi, but the plexi cracked. Thankfully it's cheap to order a laser-cut plexiglass RECTANGLE. Next time use warm water I guess.

From what I can tell, the goal of using the glue is to get it all as one piece that you can pull up at once? If that's the case why not just do as you did in the middle and cover the whole screen in cured resin so its all one part you can then scrape off. I think its probably a waste of material and not any better than the normal method of IPA and scraper, but it would probably achieve the effect that the wood glue was aiming for.

Try an Acrylic glue, it stays pretty soft and flexible, I use it for table top hobby terrain.

Wish I would have known about those plastic razor scrapers before I tried using a metal one and ripping that plastic layer over the screen on my Mars 2 Pro. I guess I have to replace the whole screen now? I can't get that plastic protector separate?

I would think if you heated the glue after it hardens using either the light of the printer or an external heat source should make the glue malleable, also possible the glue from a glue gun might work better as it has crappy adhesive capacity once it has been heated... But interesting to see

Re cosplay comment: Titebond 2 is mostly Aliphatic Resin, which scale modelers use to make windows. Unfortunately, this particular version is dyed.

I'm guessing that someone had some "loose" resin on his screen and this worked perfectly for him. Had he just used some IPA it probably would have come off. The problem with a lot of "ideas" is that they try it once and it works so they post it all over social media in the hopes that it goes viral and they make millions as the SLA printer king.

What if you laid a bead of clay or putty of some sort around the resin patch and filled it with ipa and covered it with plastic wrap, let it soak over night?

I’ve never tried this, but strictly from a chemical standpoint a substance like acetones, MEK or brake fluid should be able to dissolve the resin and wipe right off. MEK has a flashpoint of 100° should be used with Great call care an in a well ventilated area and rags should be stored in a fireproof trashcan and of course acetone and brake fluid very similar handing. You can weld just about any kind of plastic with MEK hardware stores sell it in a very diluted version. This is most likely the 1st to 3rd most dangerous chemical that the hardware store sell and is the thinner that the car manufactures used to thin car paint with. Brake fluid would be the safest, but it will also leave and oil residue. That probably would be worse than the situation you’re trying to fix, but one wipe of MEK would remove it.

remember the wood glue is just PVA glue with cellulose in it. It will fall apart and dissolve if you get it wet.

I've used a car headlight repair kit for damage to a plastic computer screen. It looks OK, but it's not flat any more. This is probably the type of polishing/abrasive you'd want if you try. Just got resin on my screen, hence the comment a year later. Alcohol and elbow grease didn't get the last little chunk. I think I'll try acetone, but upgrade to a bigger 9" machine before sandpaper/polishing. Right now I'm seeing if the layer is thin enough that it prints anyway or over cures the remaining chunk so I can scrape it off easier.

Just use a razor blade window scraper. Obviously be careful to not scratch it, but it takes resin off SO easy.

Humm... Now I am wondering, if you spray a thin layer of epoxy mould release or even a layer of oil and leave that on the screen if it would prevent leaked resin from sticking in the first place. 🤔

I use water-washable resin. I just spray the screen with Windex. Let it sit for 5 minutes and then scrape it off with my fingernails.

I dont see how the glue would bond to the resin to lift it off anyway. It was fun watching you try it though.

Nice logic. If you can't directly scratch it how do you expect that a glue will peel it off? I thought that it's gonna disolve somehow.

I had a pin hole or something and lots of resin hardened on the screen. I took a sponge and soaked it in IPA and left it for a few hours. HOWEVER, when I took the plastic scraper to the resin it lifted but also pulled up the black polarized sheet too. I ordered a new sheet, but my printer continues just to print solid square blocks now.

When installing the polarizer film, you have to orient it correctly. KZread videos exist. Also, not all films are created equal. You need a fairly high-quality polarizer.

Hot water and a sponge. Soak the sponge and let it sit for 15 mins. end up using a plstic blade or scraper. keep repeating until it removes.

Basicly, you can change a polarizer filter on your screen. Yes, you need some knowlege but it is not so difficult.

One possibility is that he lifted some edges with a razor and the put the glue down to get up under. Which makes sense, let it dry then lift it.
