An STL file contains the surface geometry of a 3D object in a machine-readable format. It is a format that describes the surface geometry of a 3D object using triangles. In this article, we will explore what an STL file is, how it works, and what it is used for.Īn STL file is a digital file format used in 3D printing. The STL file format was first introduced by Charles Hull in 1987, and since then it has become one of the most widely used file formats for 3D printing. STL files are a unique file format that is commonly used in the field of 3D printing.
