Convert PrusaSlicer & Creality .3mf files for the Snapmaker U1

PrusaSlicer and Creality Print make great multicolor files — but they don't load cleanly on the Snapmaker U1. Here's how to bridge them.

The PrusaSlicer / Creality gap

Both store color differently from Bambu/Orca: PrusaSlicer paints under its own slic3rpe attributes and has no Orca-style project config; Creality Print is an OrcaSlicer fork but tags files with its own producer string. Either way, Snapmaker Orca imports them as geometry only and drops the colors.

What the converter does

bedready.io/convert translates PrusaSlicer's paint data into Orca's format, synthesizes the project structure Orca needs, strips the Creality vendor marker, and re-tags the file as a native Orca project — then stamps the tested Snapmaker U1 profile. The painted colors map onto the U1's 4 slots, preserved exactly.

It's verified against real Creality K2 Plus / CFS files and PrusaSlicer multicolor exports.

Try it

Drop your PrusaSlicer or Creality .3mf into the converter, download the U1-ready file, and open it in Snapmaker Orca. It runs entirely in your browser — nothing is uploaded.
