PTP Create Color Lithophane Creator

About this generator

PTP Create Color Lithophane Creator is a free browser tool that turns a photo into a full-color lithophane for a CMYK filament set. It comes from the maker behind Pattern to Print, who has been making fully printed color lithophanes since 2019. Thin cyan, magenta and yellow layers carry the color and a white lithophane on top adds the shading, so the picture shows when it is lit from behind.

You upload a PNG, JPG or GIF of up to 16 MB, pick the filament set you own (American Filament, Polymaker translucent, Bambu Lab, EPAX 3D or Printed Solid), then set the lithophane resolution, your slicer's extrusion width and a print size from 25 to 250 mm per side. The default of 108 by 144 mm matches Bambu Lab's lithophane holder, and the photo is cropped for you if its ratio differs. A Preview button shows an estimate of the colors before you create the file, every download includes printing instructions, and a 0.2 mm nozzle slicer profile is linked for each brand.

It suits people with an AMS or another multi-material setup who want color photo panels without making an account. The color matching is calibrated per brand, so other filaments will give less predictable results.

What you can make

• Full-color flat lithophanes
• Color portrait lithophanes
• Panels sized for Bambu Lab's lithophane holder
• Custom-size color panels from 25 to 250 mm per side
