Information about 3MF and STL file formats

Name 3MF STL
Full name 3D Manufacturing Format Stereolithography File Format
File extension .3mf .stl
MIME type
Developed by 3MF Consortium 3D Systems
Type of format
Description 3D Manufacturing Format or 3MF is an open source file format standard developed and published by the 3MF Consortium. 3MF is an XML-based data format designed for using additive manufacturing, including information about materials, colors, and other information that cannot be represented in the STL format. STL is a file format native to the stereolithography CAD software created by 3D Systems. This file format is supported by many other software packages. It is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common, since they are more compact.
Technical details As of today, CAD software related companies such as Autodesk, Dassault Systèmes and Netfabb are part of the 3MF Consortium. Other firms in the 3MF Consortium are Microsoft, SLM and HP, whilst Shapeways are also included to give insight from a 3D Printing background. Other key players in the 3D printing and additive manufacturing business, such as Materialise, 3D Systems, Siemens PLM Software and Stratasys have recently joined the consortium. To facilitate the adoption, 3MF Consortium has also published a C++ implementation of the 3MF file format. An STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. In the original specification, all STL coordinates were required to be positive numbers, but this restriction is no longer enforced and negative coordinates are commonly encountered in STL files today. STL files contain no scale information, and the units are arbitrary.
