3MF file export
The 3MF Scene Export 
tool lets you save an additive build to a 3MF (3D Manufacturing Format) file, which is an alternative to STL.
Unlike an STL file, a 3MF file includes a data structure, so that detailed information, such as support structures, are retained.
Example of the 3MF Export Configuration dialog.
Use the options to pick what gets included in the 3MF file.
Note: This feature is available only when you select a machine with additive FFF, MJF, SLA/DLP, SLS, MPBF, or binder jetting capabilities.
