[1][2] 3MF is an XML-based data format designed specifically for additive manufacturing.

[3][4] 3MF is part of the Linux open standards project[5] and is not intended to compete in the traditional CAD space which are represented by neutral formats.

Other firms in the 3MF Consortium are Microsoft (for operating system and 3D modeling support), SLM and HP, whilst Shapeways are also included to give insight from a 3D printing background.
