About STL Format

STL (Stereolithography) is the standard file format for 3D printing. It represents 3D surface geometry as a mesh of triangles, without color or texture information. Supported by virtually all 3D printing software and services.

About GLB Format

GLB is the binary version of glTF that packages 3D geometry, textures, and materials into a single file. It loads faster than glTF for web and mobile 3D applications and is the standard for AR experiences.
