STL (File Format)

-STL is a file format native to the stereolithography CAD software created by 3D Systems. This file format is supported by many other software packages; it is widely used for rapid prototyping and computer-aided manufacturing.

-STL files describe only the surface geometry of a three dimensional object without any representation of color, texture or other common CAD model attributes.

-The STL format specifies both ASCII and binary representations. Binary files are more common, since they are more compact.

-An STL file describes a raw unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system.
