Stripping Photo Resin Miniatures

[Illithar]

Has anyone tried stripping paint from a photo resin miniature? I have one that I... well I messed up on it and It's not really salvageable now unless I can get the paint off. I've heard Simple Green is safe-ish for regular resin (I have read stories of softening and becoming more brittle after re-hardening), but I am not sure if photo resin would be any different. Are there any other cleaners that I might try or should I just dunk it in Simple Green and hope for the best?

I've used acetone-free nailpolish-remover on one Resin mini I printed a while ago. 

But that was 3DSR 405 Green resin from KUDO3D. (Translucent green)

 

Whether or not Your mini will survive the same treatment is anyone's Guess.

 

If IPA Works on the Paint you've used, you could try that. 

(Most resin prints are rinsed in IPA after printing, but before post curing)

I would also vote for IPA before trying any other cleaners.

 

Is this a model you purchased, rather than print yourself?  If you printed yourself, a re-print might be less headache.

It is one I purchased myself, one of the 3D printed mini's that Kingdom Death has put out.

 

It has some Reaper acrylics and primer on it. I will give it a soak in some IPA and see what happens.

So, update on this. I dropped the mini into a cup with some 91% IPA in it and left it there until I got home, so about 11ish hours. It has done a very good job at softening the paint and primer and it comes off fairly easily with a toothbrush. The mini was not sealed at all so that probably helps. It's also probably fouled some of the superglue but... well these are fairly easy to assemble if it comes to that.

 

I did end up getting some 99% IPA at the store today, just in case and I have put it in that solution as well. Some of the nooks and cranny's are hard to get to and that might help(?) clean them. Although, this may be a good time to invest in an ultrasonic cleaner...

 

Thank you for the help!

As a note... I know a lot of guys who do photoresin use simple green as part of the post-processing because it's a solvent for the uncured resin but leaves the cured resin alone, so if you need to do this to something else in the future it would be worth trying.

IPA is also used and what I would recommend for stripping most photo resins, although you may find it strange on some castable or flexible ones in which case you may be better re printing.

Please Do NOT use 99% IPA in an ultrasonic its extremely flammable and most ultrasonic cleaners have a heating element. Unless you want your house to be a bbq.
