Stereolithography File (.stl)

STL, short for Stereolithography, is a widely used file format in the realm of 3D printing and computer-aided design (CAD). Introduced by 3D Systems in 1987, it represents the surfaces of a 3D object through a collection of triangles, facilitating precise and efficient model creation. Utilized across various industries such as engineering, manufacturing, and healthcare, STL files are critical for prototyping and producing complex geometries. Their simplicity and compatibility with numerous software applications have cemented STL's importance in the digital fabrication landscape.

Wavefront 3D Object (.obj)

The OBJ (Object) file extension, related to Wavefront 3D Object, is a standard 3D image format developed by Wavefront Technologies. It is widely used for representing 3D geometry, including the position of vertices, texture coordinates, and normals. OBJ files are versatile and commonly employed in various CAD, 3D printing, and computer graphics applications due to their simplicity and compatibility with numerous 3D modeling programs. Introduced in the 1980s, the OBJ format has become a cornerstone in the industry, facilitating easy exchange and rendering of 3D models across different platforms.
