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.

Metadata¶
