I’ve been working on a new project and, even though it’s far from finished, I wanted to share some intermediate results. I am developing a multicolor Earth lithophane lamp with anywhere from four to seven distinct color channels. The pipeline is entirely custom - my own python code handles the color clustering, thickness mapping, and lithophane generation.

Right now, I am in the midst of testing the four-color prototype. The first flat print (first picture) already shows surprisingly clean gradients and shading. The actual model, a spherical lithophane with a diameter of 205mm (slicer preview, second picture) is printing right now. If everything works out, I'll have the first print ready by saturday.
