What is the 3MF format?

3MF — 3D Manufacturing Format

3MF is the modern 3D printing format: one file with the model, its units, colours and print settings, replacing STL in current slicers.

About the 3MF format

3MF is developed by the 3MF Consortium, founded by Microsoft and other companies in 2015. A 3MF file is a ZIP package with XML inside; unlike STL it knows its units, can hold several objects, colours and materials, and slicers such as Bambu Studio and PrusaSlicer save whole projects in it.

Older software and many 3D programs still expect STL or OBJ. Converting 3MF to STL gives a file every slicer opens; to OBJ, GLB or FBX it can be edited or shown on the web.
