ColorStack tools
Create multicolor 3D prints, lithophanes, and flat color designs right in your browser. Choose a workflow below—each page explains who it is for, what you can make, and how to open the right mode in the app.
LithoStack – lithophanes
Lithophane generatorLithoStack in ColorStack converts photos into printable lithophane heightmaps. Upload an image, preview the relief, choose a shape, and export STL without CAD.Image to lithophaneTurn pixels into printable height data. ColorStack reads brightness from your image and builds a lithophane mesh you can slice and print.Color lithophane generatorLithoStack supports color lithophane workflows that use stacked CMYK-style layers so light passing through the print reproduces saturated color—not just grayscale relief.CMYK lithophane generatorCreate CMYK lithophanes optimized for AMS filament changes and backlit viewing. LithoStack handles channel mapping, preview, and export.
ColorStack – multicolor & filament painting
Filament painting for 3D printingColorStack mode builds color-layer topography from your image so thin filament layers optically blend into a full-color front-lit print—no manual CAD painting.Multicolor 3D printing toolsColorStack is a suite of browser tools for different multicolor workflows—layer painting, backlit lithophanes, and flat multicolor plates.Image to STLTurn 2D images into 3D printable STL meshes. Pick ColorStack, LithoStack, or FlatStack depending on whether you need layers, backlit relief, or a flat plate.Multicolor 3MF export3MF carries more than geometry—it can include materials, objects, and slicer-friendly structure. ColorStack Pro exports 3MF for supported multicolor workflows.
FlatStack – flat multicolor prints
FlatStack flat multicolor printsFlatStack is for flat color surfaces, not height-based lithophanes. Upload artwork and build a thin multicolor plate ready for STL or 3MF export.Flat multicolor 3D print generatorGenerate flat multicolor plates from images—perfect for signage, merch, and branded parts where a lithophane or painted relief is not the goal.Logo to STLTurn brand marks into physical prints—desk signs, badges, magnets, and giveaway items—without modeling in CAD.SVG to STLVector SVG files are ideal for logos and signs. Rasterize or export PNG from your editor, then use FlatStack for flat multicolor plates or ColorStack mode for layered optical prints.
