Was ist eine .stl-Datei?
STL (Stereolithography) is the most widely used file format for 3D printing. It describes the surface geometry of a 3D object using triangular facets without any color, texture, or material information. STL files come in both ASCII and binary formats, with binary being preferred for its smaller file size. The format's simplicity makes it universally supported by 3D printers, slicers, and CAD software.
