FAQ
OBJ to STL Conversion
What are OBJ files?
OBJ is a 3D model format associated with Advanced Visualizer, a software suite developed by Wavefront Technologies. OBJ files contain geometry definitions of 3D models, including coordinates for each angular point, UV mapping data, texture information and details describing the faces of each polygon. Due to its frequent use, the OBJ format has been borrowed by other 3D graphics applications as well, and is currently seen as an industry standard.
What are STL files?
STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems. STL is an acronym for Stereolitography, which is a type of technology used for creating prototypes or patterns through 3D printing. An STL file contains a surface representation of such a model, without detailed specifications of aspects such as colours. STL files can only be opened with a limited number of programs.
