Why is 3MF preferred over STL for 3D printing?

3D Printing & SlicingDifficulty: Medium (Mesh Tessellation & Color/Metadata Packaging)

Dassault CATIA (.CATPart) to 3MF Multi-Material Slicing Converter

Modern 3D printing has transitioned from single-color STL to feature-rich 3MF format, popularized by Bambu Lab and Prusa. Industrial designers working in CATIA need to export complex multi-body parts directly to 3MF to preserve part colors, materials, and print orientation.
