glTF 2.0 at a glance

glTF 2.0

3D asset delivery for web, AR/VR, and game engines; cross-platform 3D content pipelines requiring efficient streaming and broad toolchain support.

3MF at a glance

3MF

Convert to 3MF when preparing models for 3D printing, especially when color, materials, units, multiple parts, or print-specific metadata should survive.

It is a strong target for additive-manufacturing workflows, maker pipelines, and print-ready model exchange.

Choose it over STL when richer manufacturing semantics are needed.
