Specification – 3MF Consortium

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.
The specification is now recognised as an International Standard: ISO/IEC 25422:2025 — Information technology: 3D Manufacturing Format (3MF) specification suite, under ISO/IEC JTC 1.
