3D Computer Modeling
Models can be built in various formats, such as RIB, DXF, 3DM, 3DMF, OBJ, X3D. For many fabbers, they then must be exported as .STL file,
The .STL format
The STL format is an interchange format for 3D models. It describes a raw unstructured triangulated surface of an object and is widely used for rapid prototyping and computer-aided manufacturing.
Scanners
Polygon File Format or the Stanford Triangle Format. (.PLY)
