The 3D Manufacturing Format (3MF) is a 3D printing format that allows design applications to send full-fidelity 3D models to a mix of other applications, platforms, services and printers. The 3MF specification allows companies to focus on innovation, rather than on basic interoperability issues, and it is engineered to avoid the problems associated with other 3D file formats.

The specification is currently under development to be recognised as an International Standard:
ISO/IEC DIS 25422 Information technology — 3D Manufacturing Format (3MF) specification suite.
Under Technical Committee : ISO/IEC JTC 1 – ICS : 25.030 35.240.50
For information on supported software, hardware and services support 3MF, see the 3MF Compatibility Matrix.
3MF members have agreed to make their necessary patent claims available for implementations of the 3MF Core Specification and all public 3MF extension specifications on a royalty-free basis.
The 3MF Consortium is a Joint Development Foundation Projects, LLC series. The Joint Development Foundation is a non-profit organization and affiliate of the Linux Foundation that provides the corporate and legal infrastructure to enable groups to establish and operate standards and source code development collaborations.
