You don’t necessarily want to go too small. Height, deviation, angle tolerance, or something similar. In the CAD package, when exporting to STL, you may see parameters for chord The model any better or smoother than the STL file, so if the STL is coarse andįaceted, that is what you can expect in the final model. The parameters used for outputtingĪ STL will affect how much faceting occurs (figures below). The triangulation ofĪ surface will cause faceting of the 3D model. Is a triangulated representation of a 3D CAD model. STL is the standard file type used by most or all rapid prototyping systems.

These step-by-step processes for converting CAD files to STL were taken straight from the mentioned companies websites. How CAD files are exported to STL is an important process for the accurate building of parts, but the conversion process can vary depending on the software.
