- 3D-printing users converting supported 3MF files
- Worth noticing
- It caps files at 50 MiB and expanded data at 32 MiB, and stops when it cannot safely determine what a project should export.
Field notes
The page sets explicit input limits: one 3MF file up to 50 MiB, with expanded data capped at 32 MiB. It says supported units and object transforms are converted to millimeter coordinates, but STL itself does not record a unit. Support is limited to 3MF Core meshes and some simple PrusaSlicer 2.9.6 projects; the page specifically notes that some Bambu Studio projects and other slicer features are unsupported.
