Information about IGS and STL file formats

Full name Initial Graphics Exchange Specification Stereolithography File Format
File extension .igs .stl
MIME type application/iges
Developed by Integrated Computer Aided Manufacturing (ICAM) 3D Systems
Type of format
Description The Initial Graphics Exchange Specification (IGS) is a vendor-neutral file format that allows the digital exchange of information among computer-aided design (CAD) systems. Using IGS, a CAD user can exchange product data models in the form of circuit diagrams, wireframe, freeform surface or solid modeling representations. Applications supported by IGS include traditional engineering drawings, models for analysis, and other manufacturing functions. 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, 3D printing 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.
Technical details The chief advantage of IGS is that it is unencumbered by licensing, i.e. it’s free. Which is probably why it’s still everywhere after all these years. But all meaningful development of IGS stopped in 1996 at version 5.3. It’s likely time to leave IGS behind for good. Especially in light of continued evolution of STEP. 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. In the original specification, all STL coordinates were required to be positive numbers, but this restriction is no longer enforced and negative coordinates are commonly encountered in STL files today. STL files contain no scale information, and the units are arbitrary.
