About These Formats
GL Binary
GLB is the binary form of the GLTF format — a compact, web-optimized container that bundles geometry, textures, and animations into a single file.
Used with
Three.js, Babylon.js, React Three Fiber, Unity, Unreal Engine, Blender, AR/VR applications.
Stereolithography
STL stores only triangulated geometry — no colors, textures, or animations. It is the de-facto standard for 3D printing slicers and CAD software.
Used with
3D printing slicers (Cura, PrusaSlicer, Bambu Studio), CAD tools, rapid prototyping workflows.
When to Convert GLB to STL
Convert GLB to STL when you need to 3D print the model. STL is the universal format for slicing software like Cura, PrusaSlicer, and Bambu Studio. Note that STL contains geometry only — colors and textures from the GLB source will not be included.
