Although the future of 3D printing continues to look bright, what is still needed is a new file format for 3D print data. Being very mindful of that fact, Autodesk, HP, Siemens, Stratasys, 3D Systems, and some others have come together to form the 3MF Consortium that espouses to get behind a truly ubiquitous file format for 3D printing. It’s really an industry partnership working toward the goal of finding a better, universally applicable 3D printing file format known as the 3D Manufacturing Format (3MF)—a file format originally developed by Microsoft, also a member of the Consortium.
The consortium admits that there is a problem that the 3D manufacturing must resolve – the current file formats used for 3D printing are in serious need of an upgrade. I totally agree.
Typically, data is passed from computer to 3D printer in STL (stereolithography) or OBJ (object) files, common 3D printing file formats. The 3MF Consortium, which now includes the research wing of General Electric, say STL and OBJ are outdated and clunky file formats with interoperability issues when used by some of the newer 3D printers, as well as contribute to 3D printing failures.
3MF Consortium Introduction
Thus, one of the driving forces behind 3MF, an XML-based open format, this new file type could contain information on the texture of a 3D print, the color of the print, and other complex characteristics. If that sounds familiar, that’s because it is—the Additive Manufacturing File Format (AMF), which has been around since 2011, solves many of the issues STL files have, and 3MF and AMF are in many respects pretty similar file formats, but let’s take a closer look.
