The 3MF consortium has released a new open source 3D file format called 3MF
for additive manufacturing. The new format gets around the limitations of the .STL format and others too. The format was developed by Shapeways, Dassault Systemes, FIT AG/netfabb GmbH, Microsoft, HP, and Autodesk. The 3MF code library lib3FM
is available for download from github.
