What is STL ?
STL is the standard file format for 3D printing: a model described as a surface of triangles, without colours or textures.

STL is what 3D printers expect, but it holds only bare geometry. People convert STL files for these reasons:
- Edit in Blender or other 3D software. STL to OBJ.
- Show it on a website or in AR. STL to GLB.
- A modern print file with units and colour. STL to 3MF.
- Game engines and animation. STL to FBX.
