File formats are used for creating and storing 3D data files. For example: ply, fbx, vrml, 3DMF, 3DML, 3DXML, obj, dxf, w3d, skp, fmz, s3d, m3g, vue, and STL are all 3D file formats. File formats must be consistent to share 3D datasets, and work within design and production platforms. There are more than 140 3D file formats. The STL file format is commonly used for many open platform dental scanning and design systems. Conversion between file formats can lead to data loss.
