What AMF and 3MF files are

AMF

AMF (Additive Manufacturing File Format) is an XML format for 3D printing standardized as ISO/ASTM 52915. Unlike STL it can describe colours, materials and several objects in one file, and it may be saved ZIP-compressed, but slicers have largely moved to 3MF.

3MF

3MF (3D Manufacturing Format) is the 3D printing format of the 3MF Consortium, founded in 2015 by Microsoft and other industry members. A 3MF file is a ZIP package holding the model in XML with its units, colours, materials and the placement of every object on the build plate, and it is the project format of slicers such as PrusaSlicer, Bambu Studio and Cura.
