The file format STL and its importance for 3D printing

Even though the STL format is around for about 30 years, it is still the single most important format for 3D printing. An STL (Standard Tessellation Language) serves as an interface between the design file (CAD) and the 3D printer. In this article, we explain the technology behind the file format, what programs to use to open the files and possible alternatives of the STL format.
