Website3MF Specification

3MF is an XML-based data format designed specifically for additive manufacturing. It differs from other common additive manufacturing formats such as STL in that manufacturing features such as hotend and bed temperatures, feed rate, part regions using multiple materials, and support structures can all be embedded into the file in addition to the model data. This removes the need to share these parameters separately when distributing a design to be manufactured.[4][5][6] 3MF is part of the Linux open standards project.[7] It is designed to be much simpler to implement than other CAD formats.[8]

The 3MF Consortium consists of CAD software developers and related companies. When first created in 2015, the consortium included Autodesk, Dassault Systèmes, FIT AG, HP, Microsoft, Shapeways, and SLM.[9] Additional additive manufacturing businesses, such as Materialise, 3D Systems, Siemens Digital Industries Software and Stratasys joined the consortium over time.[10] In addition to publishing the main specification, the consortium also manages a C++ implementation of the 3MF file format.[11]

In 2025 the 3MF format became ISO standard ISO/IEC 25422:2025.[12]
