Cleaning & Curing GratKit Rigid Resin

RuneBrush

Hi all,

Currently considering getting some of the Gratkit Rigid Resin and wondering what the optimum clean & cure method is. Have read about people using IPA, Denatured Methylated Spirits, Ethanol etc for cleaning. For curing have I've heard some people put their print into water to cure (it's even mentioned on the datasheet with the sample cure). Thought I'd ask the question to see if anyone had found one method better than another?

RuneBrush Hi, for the clean&cure

Clean
We have compared the IPA and Ethanol(95%). The result is: The IPA can deep clean the uncured resin but it may cause the tiny details affected(Being white). For the ethanol(95%) is more gentle for the prints so the tiny prints won't affected and you need to use the ultrasonic to help clean.
Cure
During curing, gases will be produced on the surface, and these gases will block more UV rays from entering. So the standard method needs more time to cure it. When you try to cure it underwater, the cure time can be decreased. Also, the result will be better, especially the tensile performance.
But need to point out, that don't over-cure the prints. The rigid print may be brittle

Hope these info will be helpful
