What is 3MF?
3MF (3D Manufacturing Format) is a modern 3D printing format developed by the 3MF Consortium (Microsoft, HP, Autodesk, and others). Unlike STL, 3MF supports colors, materials, textures, and metadata — all in a single ZIP-based package. It is the recommended format for modern 3D printing workflows.
Who uses 3MF?
Used by modern 3D printing slicers (PrusaSlicer, Cura, Bambu Studio), CAD tools (Fusion 360, SolidWorks, 3D Builder), and manufacturing workflows. The default save format in many modern slicers.
Why convert 3MF to GLB?
3MF is designed for manufacturing, not web viewing. Converting to GLB gives you a compact, web-ready file with PBR materials that loads in any modern browser. Colors and material assignments from the 3MF are preserved in the GLB output.

Frequently asked questions
Yes. Colors, materials, and textures embedded in the 3MF file are converted to PBR format and preserved in the GLB output.
3MF is the modern successor to STL. It supports colors, materials, textures, and metadata in a compact ZIP-based package. STL only stores raw triangle data with no material information.
Yes. Multi-color 3MF files from Bambu Studio, PrusaSlicer, or other slicers are converted with their color assignments preserved in the GLB output.
Usually yes. GLB with meshopt compression is typically smaller than the original 3MF, while preserving all geometry and color information.
