Information about STL and GCODE file formats

Full name Stereolithography File Format G-Code 3D Printer File
File extension .stl .gcode
MIME type
Developed by 3D Systems Massachusetts Institute of Technology
Type of format
Description STL is a file format native to the stereolithography CAD software created by 3D Systems. Many other software packages support this file format. 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 representing 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. A .gcode file is created by a slicing program, which turns a CAD drawing into a string of code that a 3D printer can understand. Then, G-code instructions are provided to a machine controller (industrial computer) that tells the motors where to move, how fast to move, and what path to follow.
Technical details 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. All STL coordinates were required to be positive numbers in the original specification, but this restriction is no longer enforced, and negative coordinates are commonly encountered in STL files today. As a result, STL files contain no scale information, and the units are arbitrary.
