3D printing services
STL is the default for printing.
STL vs glTF
Print-ready STL versus real-time glTF for 3D models and web scenes.
Practical notes
STL is the handoff format for 3D printing and simple mesh exchange.
glTF is the standard when scenes need materials, textures, and web rendering.

Web 3D, Real-time rendering, AR/VR assets, Game asset exchange
Limitations
No color or texture, No units, Triangles only
Complex scenes need tooling, Binary variant is a separate file, Not a CAD exchange format

Use-case verdicts
Winners are conditional. A format wins only when the stated condition matches your workflow.
