3mf is an additive manufacturing XML-based file format. 3mf files hold data on color, material, and all other details that can't be stored in the STL format.
X3D (Extensible 3D) is a royalty-free open standard file format used to represent 3D computer graphics. It is used to store and interchange 3D model data, including surface geometry, color, animation, and metadata. X3D files are built on the XML standard, and can be viewed and edited with a variety of 3D modeling programs.
