Information about 3MF and STL file formats

🔸 File format 3MF STL
🔸 Full name 3D Manufacturing Format Stereolithography File Format
🔸 File extension .3mf .stl
🔸 MIME type application/vnd.ms-package.3dmanufacturing-3dmodel+xml, application/vnd.ms-printing.printticket+xml, model/3mf model/stl, model/x.stl-ascii, model/x.stl-binary
🔸 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. Many other software packages support this file format. 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 representing 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 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, while Shapeways are also included to give insight from a 3D Printing background. In addition, 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. All STL coordinates were required to be positive numbers in the original specification, but this restriction is no longer enforced, and negative coordinates are commonly encountered in STL files today. As a result, STL files contain no scale information, and the units are arbitrary.
