Multicolor 3MF export
3MF carries more than geometry—it can include materials, objects, and slicer-friendly structure. ColorStack Pro exports 3MF for supported multicolor workflows.
Generate 3MF with printer profiles from the built-in library.

STL vs 3MF for multicolor
| STL | 3MF | |
|---|---|---|
| Color metadata | Usually none | Can include objects and materials |
| Setup time | Manual filament changes | Often faster for AMS workflows |
| Compatibility | Universal | Best in modern slicers |
Frequently asked questions
- Is 3MF export free?
- STL export is available on the free tier with limits. Advanced 3MF export is a Pro feature with daily limits on some modes.
- Which slicers are supported?
- Profiles target Bambu Studio, OrcaSlicer, PrusaSlicer, and other Orca-based forks.
- Can I still use STL?
- Yes. STL remains the universal fallback for any FDM slicer.
