Originally developed by Microsoft, it is the native 3D format in Windows. 3MF (3D Manufacturing Format) is similar to AMF but less standardized as it is created by a consortium of companies.Being XML-based, it will store additional data such as orientation, scale, patterning multiple objects, non-planar edges, and graded materials. AMF (Additive Manufacturing Format) is an alternative to STL for 3D printing.One of its benefits is the possibility to assign properties such as texture data separately for both sides of a face.

PLY (Polygon) is a more extensive format developed at Stanford to aid the storage of 3D scanning data.

Besides vertex positions, it also stores surface normal plus a UV coordinate that can be mapped to an external texture.
