What Bambu Studio workflows need from a file
A Bambu Studio workflow can start from simple geometry, but multi-color projects need more planning. The file should match how much information you expect to preserve.

When STL is enough
STL is enough for a simple one-color print where you plan to choose printer, filament, supports, and slicer settings inside Bambu Studio.
When 3MF is better
3MF is the better handoff when the model has color assignments, material context, or project information that should arrive with the file.
Recommended PrintNext workflow
Use Color Studio to plan colors, export a color-ready 3MF, then open that file in Bambu Studio and verify filament mapping before printing.

FAQ
Common questions
Should I use STL or 3MF for Bambu Studio?
Use STL for basic geometry. Use 3MF for color, material, or richer project handoff.
Is 3MF useful for AMS workflows?
Yes. A 3MF handoff can make it easier to preserve color intent before you verify filament mapping in Bambu Studio.
Can I color an STL before Bambu Studio?
Yes. You can plan color in Color Studio, export 3MF, and then verify the result in Bambu Studio.
Do I still need to check settings in Bambu Studio?
Yes. Always verify printer profile, filament slots, colors, supports, and print estimates before printing.
