About STL
STL is the classic 3D printing format. Pure triangulated geometry — no textures, no colors — just the shape.
- 3D printing
- CAD interchange
- Rapid prototyping
About GLB
GLB is the binary flavor of glTF — a single file that bundles geometry, materials, textures and animations. It's the default web-3D format and the recommended export for Roblox mesh accessories.
- Roblox meshes & UGC
- Three.js / React Three Fiber
- AR / WebXR
How to convert STL to GLB
- Open Meshlox Studio and drag your STL file into the canvas.
- Meshlox auto-detects geometry, materials and animation data.
