STL (Standard Tessellation Language) ASCII

3d · also known as Stereolithography File (ASCII)

STL is a 3D modelling file format created by 3D Systems. An STL file is a triangular representation of a 3-dimensional surface geometry. The surface is tessellated or broken down logically into a series of small triangles (facets). Each facet is described by a perpendicular direction and three points representing the vertices (corners) of the triangle. These data are used by a slicing algorithm to determine the cross sections of the 3-dimensional shape to be built by the fabricator.
