What GLB and STL files are
GLB
GLB is the binary form of glTF, packing a model's scene description, geometry, textures and animation into one file. That makes it easy to share and fast to load, which is why it is widely used for 3D on websites, in game engines and in AR viewers such as Google's Scene Viewer.
STL
STL is the standard file format for 3D printing. It describes a model's surface as a mesh of triangles without colour, texture or units, which keeps it simple and universally supported by slicers and CAD software.
