STL vs OBJ
Stereolithography
STL is the standard format for 3D printing. It describes only the surface geometry using triangular facets, without colors, textures, or other attributes.
Wavefront OBJ
OBJ is a simple, widely-supported 3D geometry format. It stores vertex positions, normals, and texture coordinates in plain text, making it easy to parse and edit.
