PrusaSlicer to Bambu Studio

Yes. Bambu Studio opens a PrusaSlicer file as geometry only, so convert it first to bring the settings along.

Does Bambu Studio open the file without converting?

The geometry loads. The settings do not: Bambu Studio says The 3mf is not from Bambu Lab, load geometry data only. Converting writes the settings in Bambu Studio's own spelling.

What carries over?

Every PrusaSlicer bed becomes a plate. Every filament carries. Modifiers, negative volumes and the other volume roles keep their roles and their settings. Supports, seams and fuzzy skin paint keep their meaning. Colour paint is decoded and written again in Bambu Studio's form. Object and part settings are translated key by key.

What gets dropped?

Layer ranges. The Changes panel names each one, for example Layer range / not carried / preslice does not write Bambu Studio layer ranges. If a model cannot be split into parts, it stays as it was and the panel counts it as N objects left as it was. Other shared losses are in what a conversion cannot carry.

Which Bambu Studio settings will not come from my file?

About 425 keys Bambu Studio declares have no PrusaSlicer counterpart, such as alternate_extra_wall. Each takes its value from the Bambu Studio printer profile you picked, then from Bambu Studio's own default where that profile sets nothing.

Can I convert it back?

Yes. See Bambu Studio to PrusaSlicer.
