I imagine some people here have tried printing objects to fairly tight tolerances. Have people compiled a reference on how much the various materials tend to shrink, post-wash and cure? At some point I thought I found some technical documentation from Formlabs with these estimates, but I am unable to find them now.
I certainly understand this is a very non-linear phenomenon so the answer will depend on the shape of the object printed, and the resin used. I’d like to try, for example, printing off a lego-style brick for my son. If I had some first-order estimate of shrinkage it would give me a starting point.
Failing that, I will print off a 1cm^3 block and measure shrinkage.
