Preview any image as a multi-filament 3D model, tune the colours, and see exactly what you'll get before you print. Card Relief lifts posters and photos into real depth. Halftone turns any image into a colour 3D print. Drop in a photo, a poster, pixel art or album cover and Halftone works out how to build it from the filaments you actually own — choosing colours, stacking translucent layers, and giving you a step-by-step swap schedule for your printer. No painting, no multi-material hardware required (though it supports that too). HOW IT WORKS Halftone models the physics of light passing through thin filament layers, so the preview you see is what your print will look like. It picks the best filaments from your library, decides where each colour changes, and shows you the whole thing as a 3D model you can spin around before you commit a single gram of plastic. CARD RELIEF Halftone's headline mode uses an on-device depth model to lift the subject of your image out of the card — the way a UV-printed relief does — while per-pixel colour rides the surface. Movie posters, portraits and game art come out with real dimension, not just a flat lithophane. Dithering keeps gradients smooth; the depth engine downloads once and runs entirely on your Mac. MORE WAYS TO PRINT • Colour relief — classic layered colour prints for single-nozzle printers • Isolation — crisp separated colours for logos and flat art • Flat — face-down slabs for keychains, coasters and cards • Terrain — bounded tonal relief with per-pixel colour MADE FOR YOUR PRINTER Set up your printer once (Bambu Lab AMS, Prusa, or any single-extruder machine) and Halftone respects your nozzle, layer height and colour slots. Add your own filaments to the library — any brand, any material — with simple opacity presets. SO MUCH TO EXPLORE Load images, build previews, tune filaments, edit regions, and see exactly what you'd get. When you're ready to print, Halftone Pro unlocks: • STL files for every filament • Multi-material 3MF for your slicer • Filament swap instructions for single-nozzle printers PRIVATE BY DESIGN Your images never leave your Mac. All processing — including depth estimation — happens locally. Halftone collects no data. Halftone runs natively on macOS 13 and later, on Apple silicon and Intel Macs.
