What To Do When Your 3D Resin Print Fails

If you use a resin 3D printer, you WILL have a failed print sooner or later. When this happens, you'll need to make sure the vat and FEP is clear of any cured resin before you can start the next print with confidence. In this video, I show you my process of cleaning up and resetting after a print failure.

That trick with the used resin is brilliant. I would have never came up with using it as a handle to pull out the sheet.

[@MSH420]

Your cadence is spot on, very easy to follow and I probably won’t need to watch it four times to retain it. Good job!

[@Stevebroza]

curing the old supports to the FEP cleaning cure is very good idea!

[@fraaancooo]

elegoo have a button for this :)

Thank you for this I needed this tutorial

[@Fumblebuster]

Nice, thanks for this.

[@dadembira]

thans very good tip

[@backpacker3421]

The paper filter/strainers are cheap, and you can actually reuse them as long as they continue to let the resin through. I just leave it in the funnel, and put the funnel in a plastic bowl to catch any drips after I'm done. I can usually get 5-10 uses out of one strainer.

[@Kastoruz]

Excellent video tutorial, especially if you are new to 3D printing. Saving this for later.

[@Sonic32084]

Great video for a newbie like me. I’m starting off pretty well but have had a couple of failures so far. I need to use the clean feature on the printer.
I don’t know if you can help but the two fails I’ve had seem to be halfway through the print. One layer doesn’t stick and then it’s game over. The resin that has cured has a flat layer where the print just stops. Should I set my “wait after cure time” a bit higher? It was at 1 second.

[@davidburns9766]

Just to skip a step - you should have left the resin in the vat, done the tank clean, THEN poured the resin into the bottle. It saves you emptying the vat twice.
You’re still straining the resin with the filter that way, AND cleaning the failures from the fep.

Great video! How often do you clean your vat? Like completely empty it of resin and get in there with IPA or something?

[@FigureFeedback]

I only completely clean the vat when I change to a different resin. I used to clean it after a failure, but now I use the full screen exposure method to peel off a thin layer of cured resin after failures.

[@that_Ranjit]

@@FigureFeedback thanks for the reply. i guess i have a lot of anxiety when it comes teeny tiny cured bits floating around in the vat. but it is a pain to go through the whole cleaning process with the vat. so you've never cleaned your fep sheet?

[@FigureFeedback]

Yes, I've cleaned the fep before with IPA. I always completely clean the vat and fep sheet if I switch to a different type/brand of resin. I'll also drain the vat if I have a big failure where part of the model is floating in the resin to be on the safe side.

[@christopherarendt3531]

Thanks man great for noobs like me 😂

[@tapist3482]

My tub has a lip but resin is too thick to flow along the lip as one would expect so at first time I spilled resin everywhere...

[@donniem7979]

So many supports I wonder what the heck could have caused that. Maybe more exposure time and slow down the speed from screen to rising height?

[@FigureFeedback]

I'm not too sure either. Every couple prints with this resin fails. I wonder if it's the heat. It's 83 degrees fahrenheit in my garage and I'd imagine it's warmer in the enclosure.

[@619timbercali]

​@FigureFeedback as we know, uv reaction creates heat as well so when you're printing, the resin will actually have a higher temp than the enclosure. I've recorded 80°f in my vat while my room was about 73, enclosure inside was 76.

[@frkop]

but how fix this problem ?

[@FigureFeedback]

That's a big question because there can be various reasons for why a print can fail. Sometimes it's just bad luck. Other times it can be due to lack of supports or badly placed supports, the orientation of the model, the exposure time, the lift speed, the temperature of the resin etc. It's something that needs to be evaluated on a case by case basis.
