Got my shit together enough to test my siraya tenacious resin out. It's very UV-sensitive so it hardens quickly, but it still has a bit of flexibility and tackiness so it works okay for making stamps in a 3D printer. Maybe setting up a stamping rig and conventional stamping resins would still be worth looking into...
Wait, shit, I just noticed some of the features didn't print at all--I suspect the normals on the model were bugged after converting, so I'll have to recalculate them and print it again aaaa
it just occurred to me this is the first time I made a stamp since, uh... 2nd grade?
