ColorStack

CMYK lithophane generator

Create CMYK lithophanes optimized for AMS filament changes and backlit viewing. LithoStack handles channel mapping, preview, and export.

Designed for makers using cyan, magenta, yellow, and white/black filaments on multicolor printers.

Who it is for

  • Bambu Lab P1/X1/A1 owners with AMS
  • OrcaSlicer and Bambu Studio users
  • Makers comparing CMYK lithophane vs manual painting

What you can make

  • AMS-ready color lithophane 3MF (Pro)
  • Custom-shaped backlit panels
  • Photo gifts with transmitted color

How it works

  1. 1

    Load your photo

    Use a well-lit image with distinct colors for cleaner channel separation.

  2. 2

    Select CMYK lithophane

    LithoStack assigns colors to printable layers for backlit transmission.

  3. 3

    Set physical size

    Match lamp diffusers, frames, or build plate limits.

  4. 4

    Export 3MF for AMS

    Pro users can export a 3MF package aligned to printer profiles in ColorStack.

Export formats

STL (heightmap relief) · 3MF (CMYK / AMS workflows on Pro)

Frequently asked questions

Why CMYK instead of RGB filament?
CMYK maps cleanly to cyan, magenta, yellow, and key (black/white) spools—the standard approach for transmitted-color lithophanes.
Does this work with Bambu Studio?
Yes. Export 3MF and open it in Bambu Studio or OrcaSlicer with your printer profile.
How many filament changes should I expect?
It depends on image complexity and layer settings. The 3MF export is meant to reduce manual setup.

Color lithophane generator

LithoStack supports color lithophane workflows that use stacked CMYK-style layers so light passing through the print reproduces saturated color—not just grayscale relief.

Multicolor 3MF export

3MF carries more than geometry—it can include materials, objects, and slicer-friendly structure. ColorStack Pro exports 3MF for supported multicolor workflows.

Image to lithophane

Turn pixels into printable height data. ColorStack reads brightness from your image and builds a lithophane mesh you can slice and print.

3MF vs STL for multicolor 3D printing

STL remains universal geometry. 3MF can package multicolor structure and slicer-friendly metadata. Choose based on your printer and patience for manual setup.
