There’s a tool I use to generate depth maps (grayscale images that denote depth using white as “no depth” and black as “as deep as it goes” and breaking up the layers in between into the number of grays the image uses) from STLs (meshes for, generally, 3D printing) so we can take our prototype 3D printed molds and reproduce them in aluminum using our fiber lasers (in theory, when everything is working correctly).
