I am trialing some parts that are used in cleanroom environments as printed instead of traditionally machined. They need to sit flat on the table as it will be a reference for other components. I am using Biomed Clear and orienting such that the bottom is flat to maintain circularity of printed dowel pin holes. The prints come out flat but when I cure in the FormCureL they keep warping. Is there a minimum thickness of basically a flat plate that won’t warp?
