Thanks for the explanation. Got an Anycubic Mono for my birthday and have been checking this thread out periodically to see what everyone is doing. I started teaching myself solid modeling in Freecad, mostly to make small parts and wheels that are otherwise unavailable. You seem to have jumped in to 3d printing with both feet. Hopefully I can get to printing mode in a couple more weeks. I bought Anycubic Standard Resin+, and I notice that the resin parameters lists a "molding shrinkage" of 4%. Do you scale thing up to account for shrinkage?
