About OBJ

OBJ is a 3D model format that stores geometry data like vertices, edges, faces, and texture coordinates. Developed by Wavefront Technologies, it's widely supported across 3D modeling and game engines. OBJ files can also be paired with .MTL files for materials.

About STL

STL is one of the most widely used formats in 3D printing. It represents the surface geometry of a 3D object using a mesh of triangles. STL files do not store color or material data but are ideal for rapid prototyping and additive manufacturing.
