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

Liquid level sensing is a tremendously important engineering challenge that is critical in many industries around the world, from factories to municipal water systems. Though technology has made progress in leaps and bounds in recent years, many traditional technologies are still widely used for a plethora of possible reasons, even on new systems. For example, one may be simply maintaining or repairing an old system because it seems quicker or less costly, it may be what the engineers are familiar with, parts may still be on hand, or maybe it “just works.” However, there are many important reasons to consider newer technologies, such as hydrostatic level sensing.
Implementing and maintaining liquid level control systems can be complex, and varies significantly depending on the installation. Therefore, many common challenges com
