Convert PrusaSlicer files to the Snapmaker U1
Drop a PrusaSlicer or MMU .3mf into BedReady and get a U1-ready file back — painted colors, supports and seams translated into Snapmaker Orca's format and the real U1 profile applied. Free, in your browser, nothing uploaded.
🔒 100% in your browser — your file is never uploaded.
The problem
PrusaSlicer stores everything you painted — MMU colours, custom supports, seam placement — under its own slic3rpe: attributes, alongside a Prusa/MMU printer profile and its own filament palette. Snapmaker Orca can't read that directly: it tags the file as a foreign Prusa project, drops the paint data, and loads the model as plain grey geometry with the wrong profile. Redoing the colour painting, supports and seams by hand defeats the point of a project file.
What BedReady does in one click
- ✓Translates PrusaSlicer paint data — colors, supports and seams — into Orca's paint_* format
- ✓Rewrites the Prusa generator string so Orca loads the file as a native U1 project
- ✓Applies the real Snapmaker U1 profile in place of the Prusa/MMU one
- ✓Reads the filament palette from the Slic3r_PE config and maps colors to the U1's 4 slots
- ✓More than 4 colors? Full Spectrum mixes 2–3 filaments to reproduce the extras
- ✓Runs 100% in your browser — nothing uploaded, free, no account
Works with files from PrusaSlicer, OrcaSlicer, Bambu Studio, MakerWorld and Creality Print. See the full feature list & comparison.
FAQ
Does it read my MMU color painting?
Yes. PrusaSlicer stores MMU colour painting as slic3rpe:mmu_segmentation paint data. BedReady translates that into the paint_color format Snapmaker Orca reads, so every painted face maps onto the U1's 4 slots instead of loading as plain grey geometry.
What about painted supports and seams?
Those come across too. BedReady translates PrusaSlicer's custom-support painting (slic3rpe:custom_supports) and seam painting (slic3rpe:custom_seam) into Orca's paint_supports and paint_seam attributes, so your enforced/blocked supports and seam placement survive the conversion.
Which PrusaSlicer version and export format should I use?
Export the project as a .3mf (File → Export → Export project as 3MF, or Save Project) rather than a plain STL. The .3mf is what carries the paint data and the filament palette; recent PrusaSlicer 2.x releases all use the slic3rpe paint attributes BedReady understands.
Why can't Snapmaker Orca just open the PrusaSlicer file?
PrusaSlicer writes its paint data under its own slic3rpe namespace and tags the file with a Prusa generator string. Snapmaker Orca only fully trusts its own native projects, so it treats the Prusa file as foreign — dropping the paint and loading geometry only. BedReady renames the paint attributes and rewrites the generator so Orca loads it as native.
Is my file uploaded anywhere?
No. The conversion runs entirely in your browser — the .3mf never leaves your device, there's no account, and it's free.
