I have been using MSLA resin printing for a while now to create injection molds for product prototypes. The product I have been working on recently is a DIN rail mount for a B/W Controls relay, and it is wider and flatter than parts I have done before. I was struggling to get a 3.75” x 5.25” mold insert to print without warping on my Anycubic Photon Mono X, when I came across this blog post with a really clever technique for reducing shrinkage and warping in prints.
In short, by breaking each layer into multiple interleaved exposures, the shrinkage due to resin curing can be reduced dramatically. Great, so I had a new tool to try to improve my dimensional tolerances. The author of the blog, Jan Mrázek provided a script for UVTools to convert a sliced file into
