Convert GLB Models to Modern Print Format 3MF
Export GLB files into 3MF, the next-generation 3D printing format. 3MF carries geometry, color, materials, and print settings in one file, replacing STL in modern slicer workflows.

Color and Material Data Included
Unlike STL, 3MF supports per-face and per-object color assignments. The converter transfers color data from the GLB into the 3MF so modern color-capable printers can reproduce your model accurately.

Native Support in Modern Slicers
3MF is the preferred input format for Bambu Studio, PrusaSlicer, Cura, Orca Slicer, and Microsoft 3D Builder. These slicers take full advantage of 3MF features that STL simply cannot carry.

One File, All the Information
A 3MF file is a ZIP archive containing geometry, materials, thumbnails, and print metadata. Everything a slicer needs ships in one package, avoiding the external texture and MTL reference issues of older formats.

GLB and 3MF: Rendering vs. Manufacturing
Why Use It
No Software to Install
The conversion runs entirely on the server. No Blender add-ons, no command-line tools, no local 3MF libraries to configure.
Color Data Preserved
Per-face and per-vertex color information from the GLB is mapped into 3MF material definitions, enabling color-accurate printing on supported printers.
Modern Slicer Ready
3MF is natively supported by Bambu Studio, PrusaSlicer, Orca Slicer, Cura, and Microsoft 3D Builder without any conversion or workaround.
Replaces STL for Advanced Workflows
3MF was designed by the 3MF Consortium specifically to overcome the limitations of STL. It supports multiple objects, colors, materials, and print metadata in one file.

Frequently Asked Questions
What advantages does 3MF have over STL for printing?
3MF supports per-face color, material definitions, multiple objects, print settings, and thumbnails in a single file. STL stores only triangle geometry with no color or material support, and cannot represent multiple objects with independent settings.
Does the 3MF output include colors from the GLB?
Yes. Color data from the GLB, whether from vertex colors or material base colors, is mapped into 3MF material and color definitions so color-aware slicers and printers can use it.
Which slicers support 3MF natively?
Bambu Studio, PrusaSlicer, Orca Slicer, Cura, and Microsoft 3D Builder all support 3MF natively. Most modern slicers released after 2018 handle 3MF without plugins.
What is the maximum GLB file size?
The converter supports GLB files up to 100 MB. Complex multi-mesh GLBs with embedded textures may produce larger 3MF archives.
Are animations from the GLB included in the 3MF?
No. 3MF is a fabrication format and does not support animation. Only the base mesh geometry and color or material data are transferred to the 3MF output.
