@leonhart88 might have some more thoughts and insight, but we find that making sure your parts are completely dry of IPA after washing can make a big difference. If the part is still slightly saturated with IPA, your part can warp during and after curing. @leonhart88 has conducted his own experiment where he cured right out of the wash, after drying with compressed air, after air drying overnight, and after drying in a dehydrator, and found a pretty significant correlation. Phil if you could link to that, that’d be great, I can’t seem to find that thread
Edit: Found it! Post cure warp in SLA linked to insufficient drying

@leonhart88 feel free to link the full YT video if that’s done!
