Convert FBX to 3MF
Convert a FBX file to 3MF in your browser. Free, no upload, no sign-up.
Convert FBX files to 3MF directly in your browser. The converter parses the FBX mesh, rebuilds it in memory and writes it out as 3MF, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. 3MF records the unit and can hold several objects with colors, so the model opens in the slicer at the right size without guessing.
How to convert FBX to 3MF
- 1Drop your FBX file
Drag a .fbx file onto the box above or click to choose one. Binary and ASCII FBX (version 7.0+) are read. Animation, rigs and external textures are ignored; only the mesh geometry is converted.
- 2Check the preview
The model renders in 3D so you can confirm it loaded correctly. Dimensions, volume and triangle count are shown next to it; open edges are flagged if the mesh is not watertight.
- 3Download the 3MF
Adjust the export options if needed and click download. The exported file declares millimeters as its unit and contains the mesh as a single object.
What is a FBX file?
FBX is Autodesk's proprietary interchange format for animation and game assets. It carries meshes, rigs, animation, cameras and materials. Because it is closed and complex, FBX files are rarely accepted by 3D printing tools directly.
Commonly used by: Maya, 3ds Max, Unity, Unreal Engine, Mixamo

What is a 3MF file?
3MF is the modern replacement for STL, published by the 3MF Consortium (Microsoft, Autodesk, HP, Prusa and others). It is a ZIP archive containing XML that stores units, colors, materials, multiple objects and print settings. Slicers such as Bambu Studio and PrusaSlicer use it as their project format.
Commonly used by: Bambu Studio, PrusaSlicer, Cura, Windows 3D Builder, Fusion 360
