Just a beat after announcing the its ColorMix implementation of FullSpectrum color interpolation printing, Prusa has announced a neat ColorMix Shading web app that lets you dramatically shade prints to achieve filament mix-like effects. Just upload your STL, set the colors you're using, and reposition the "light" to set new shaded perspectives on your model. It's quick, easy, integrates directly with EasyPrint, PrusaSlicer or, for non-Prusa users, exports directly to 3MF. Read more about it on the Prusa blog.
