Everything the converter does
Drop in a multicolor .3mf and get a Snapmaker U1-ready file — colors, profile, and prime tower all handled. Free, in your browser, nothing uploaded.
Works with any slicer
- ✓Converts .3mf from MakerWorld, Bambu Studio, PrusaSlicer & OrcaSlicer
- ✓Full Creality Print support
- ✓Re-tags Prusa/Creality files as a native Orca project — no more “geometry only”
- ✓Reads PrusaSlicer / Orca ColorMix files — keeps their 4 base filaments and mixes, Full Spectrum on
Colors, done right
- ✓Painted multicolor mapped onto the U1's 4 slots
- ✓Original colors preserved exactly — including text, logos & fine detail
- ✓Color matching tuned to what the U1 actually prints (CIEDE2000 + the slicer's own pigment model)
- ✓Translates PrusaSlicer paint data (colors / supports / seams)
More than 4 colors
- ✓Full Spectrum: reproduce more colors than 4 slots by dithering 2- and 3-filament mixes
- ✓Mix from your own filaments (CMYK or any 4) with an editable recipe per color
- ✓Spots height-banded models and gives you the exact filament-swap heights
- ✓Mixed-color layer-height control for smoother blends

Tuned for the U1
