Blender
The Good
- Completely free and open-source for everyone
- Allows for advanced editing and repair before exporting
- Supports a huge range of formats beyond just GLB and 3MF
The Bad
- Steep learning curve for users who only need to convert files
- Overkill and inefficient for simple, quick format conversions
Blender is a complete, free, and open-source 3D creation suite that can import GLB and export 3MF files as part of its vast toolset, offering unparalleled control over the process.
2026 Analysis
While not a dedicated converter, Blender is a powerhouse of 3D creation. Users can import a GLB, make any necessary edits, repairs, or optimizations manually, and then export it as a 3MF. This is a great option for artists who need to modify a model during the conversion process. However, this requires navigating a complex interface, making it far less efficient for straightforward conversions compared to dedicated tools.
