Multiple file-format choices exist, but you might want to consider taking additional steps when saving your parts for 3D printing.
One can choose from a number of file formats for 3D printing, and in general they all work fine. However, understanding what mesh resolution is needed for each part can affect the size of the file, which may create lag when transferring data. In addition, not everything transfers smoothly from a CAD drawing to the printer. This article will look at file resolution, clearance between moving parts, geometric interferences, and more things to keep in mind when moving your CAD drawing to a 3D printer.
