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.Īn 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. gcode file is created by a slicing program, which turns a CAD drawing into a string of code that a 3D printer can understand. Binary files are more common since they are more compact.Ī. The STL format specifies both ASCII and binary representations. STL files describe only the surface geometry of a three-dimensional object without representing color, texture, or other common CAD model attributes. It is widely used for rapid prototyping, 3D printing, and computer-aided manufacturing. Many other software packages support this file format. STL is a file format native to the stereolithography CAD software created by 3D Systems.
