When to convert GLB to 3MF
You generated a colorful model with an AI tool (Meshy, Tripo, Hunyuan) and want to 3D-print it in full color on a Bambu (AMS), Prusa (MMU) or full-color resin machine. STL throws the color away; 3MF keeps it. This converter bakes the GLB’s texture into per-vertex color so your slicer prints the model as it looks.
GLB vs 3MF: what’s the difference?
GLB is the single-file format AI generators like Meshy, Tripo and Hunyuan produce, carrying geometry, UV coordinates, PBR materials, textures and animation. 3MF is the modern zip-based format Bambu Studio and PrusaSlicer save by default, storing geometry together with color and print settings. Converting GLB to 3MF bakes the GLB’s texture down into per-vertex color, so your AI-generated model arrives ready for full-color printing on a Bambu AMS or Prusa MMU.
What GLB → 3MF keeps and drops
Preserved
- ✓Full mesh geometry
- ✓Surface color, baked from the texture into per-vertex color
- ✓Real-world scale and proportions
Dropped
- ✗Animation and rigging — 3MF is a static print format
- ✗PBR detail beyond base color — metalness, roughness and normal maps are not printable
- ✗Fine texture resolution, since color is sampled per vertex rather than per pixel
How to convert GLB to 3MF
- 1Drop your .glb file onto the box above, or click to browse.
- 2The file is parsed and the texture baked to color in your browser — nothing is uploaded.
- 3Check the colored 3D preview, then click “Convert to 3MF”.
- 4A .3mf file downloads, ready to open in Bambu Studio or PrusaSlicer.
Color is baked per-vertex, so fine texture detail softens — denser meshes hold more color detail than low-poly ones. Metalness, roughness, normal maps and animation do not carry, since none are printable. For a plain single-color print, GLB to STL is smaller and simpler; choose 3MF only when you want color.
GLB to 3MF — FAQ
Does this actually keep the color?
Yes. The GLB’s base-color texture is sampled at every vertex and written into the 3MF as per-vertex color — the form Bambu Studio, PrusaSlicer and Cura read for full-color printing.
Will it print in color on any printer?
Color prints on multi-material setups (Bambu AMS, Prusa MMU) or full-color resin / binder-jet machines. A single-extruder printer ignores the color but still prints the geometry.
Is my GLB uploaded anywhere?
No. Texture baking and 3MF packing run entirely in your browser tab; your file never leaves your device.
