STL file format

STL (*.stl)

stl file format for 3d printingSTL format is created by 3D Systems.  This file format is supported by many other software packages. It is widely used for rapid prototyping with 3D printers 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. An STL file describes a raw unstructured triangulated surface.

STL file format

is simple and easy to output. Consequently, many computer-aided design systems can output the STL file format. STL can also be used for interchanging data between CAD/CAM systems and computational environments such as Mathematica.
