3D Manufacturing Format (3MF)¶
3MF is a neutral, open-source file format developed by the 3MF Consortium to store and exchange 3D models for additive manufacturing. It uses a ZIP-based container with an internal XML structure to describe geometry, materials, metadata, and print instructions in a compact, extensible format.
🔍 See 3D Data Resources for details and definitions.
Extensions¶
.3mf
Structure¶
instant3Dhub preserves 3MF’s hierarchical object model structure that allows representing assemblies and reusable components.
Geometry¶
3MF uses mesh-based geometry to define the shape of 3D objects.
Tesselation¶
Geometry is defined as triangle meshes using indexed vertices and faces and is supported by instant3Dhub.
B-Rep¶
3MF does not support B-Rep geometry.
PMI & Model Views¶
3MF does not support PMI or Model Views.
