3MF (3D Manufacturing Format) was developed by the 3MF Consortium in 2015 as a modern replacement for STL. A 3MF file is a ZIP archive containing XML geometry data plus color, material, texture, and print setting metadata. Unlike STL, 3MF supports full-color models, multi-material assemblies, and structured metadata.
For multi-color FDM printers (Bambu Lab AMS, Prusa MMU), 3MF carries per-part color and material assignments that STL cannot express.
HP Multi Jet Fusion and other powder-bed systems use 3MF to carry full-color and material data natively.
3MF files can bundle slicer profiles and print settings for exact configuration reproduction.

Commonly converted from STEP or STL for additive manufacturing, or to STL for legacy slicer compatibility.
