This repository contains the Volumetric Extension that extends the 3MF 3D Manufacturing Format Core specification.

This extensions provides additional support for voxel data within 3mf files. This will enable the representation of objects with variable material properties throughout their volume, like opacity, color, strength etc.

See the 3MF examples repository for 3MF volumetric sample files.

This version of the 3MF Volumetric Extension is a pre-release version. Consumers and producers can implement this version and use it, however, future version of this specification, in particular the “Published” version, might not be backwards compatible to this version.
