White spots on resin models

[dwbullock]

I don't have a resin printer.  I normally get my resin prints off Esty, and have had no real issues.  I understand the white spots can be a sign the models were not properly washed and/or cured.  However, will it cause a problem down the line?  Is there a way I can clean it up without using all the Walter White chemicals that 3d resin requires?



Thanks.

I always just assumed it was soap scum. I've painted spotty prints (even copper plated a fair few) and they seem fine.

At a glance it would seem to be to be spots where the dozens of gates were removed/broken/clipped off.

The order came with 19 goblins.  Maybe 5 have those spots.  I wondered if it was where supports had been attached, but the spots are in harder areas to place supports - more undercuts, detailed areas. 

Google Fu suggested they just weren't cured well enough.  Don't want the horror stories of models 'melting' months after I paint them.  First real resin printed models I've had that show these spots. 

Sounds like I should just ignore them, though?

I doubt they are un-cured sport of resin though, or at least not enough to "melt" the model or anything - printer resin is a UV-cure type, and not two-part stuff that can be finicky to mix.

I think that it's just a bit of residue left over from the curing and cleaning process. I'd tickle the trouble spots with a fresh scalpel blade to loosen anything there, and then give them a gentle targeted scrub with some medium-warm water and dishsoap using a stiff toothbrush. After they're dry, I'd say anything left is probably inert, and you're good to prime.
