Convert FBX to 3MF

Understanding FBX and 3MF file formats

FBX (Filmbox) is a popular 3D file format developed by Autodesk, widely used for exchanging 3D assets between software such as Maya, 3ds Max, Blender, and game engines. It supports complex geometry, textures, animations, and scene information.

3MF (3D Manufacturing Format) is a modern file format designed for 3D printing. Developed by the 3MF Consortium, it stores 3D models, color, material, and other manufacturing data in a compact, open XML-based structure, ensuring compatibility and high fidelity for additive manufacturing workflows.

Why convert FBX to 3MF?

Converting FBX to 3MF is essential when you want to prepare 3D assets created in animation or modeling software for 3D printing. The 3MF format ensures that the model's geometry, color, and material information are preserved for accurate and efficient 3D printing.

How to convert FBX to 3MF

Direct conversion from FBX to 3MF is not always supported in all 3D software. The most reliable workflow involves using a 3D modeling application that supports both formats or utilizing a dedicated file converter.

Using Autodesk Fusion 360

1. Open Fusion 360 and import your FBX file via File → Open.
2. Check and repair the model if necessary to ensure it is watertight and suitable for 3D printing.
3. Export the model by selecting File → Export and choose 3MF as the output format.

Using Microsoft 3D Builder

1. Launch 3D Builder and open your FBX file using Open → Add.
2. Make any required adjustments or repairs to the model.
3. Export the file by selecting Save As and choose 3MF as the format.

Online converters

Web-based tools like AnyConv or Aspose 3D Converter can convert FBX to 3MF without installing software. Simply upload your FBX file, select 3MF as the output, and download the converted file. Note that online converters may have file size limits and privacy considerations.

Best software for FBX to 3MF conversion

• Autodesk Fusion 360 – Professional-grade, supports both FBX import and 3MF export.
• Microsoft 3D Builder – Free, user-friendly, and supports both formats.
• Blender (with plugins) – Open-source, requires add-ons for 3MF export.
• Online converters – Convenient for quick, small conversions.

Tips for successful conversion

• Ensure your FBX model is manifold (watertight) and free of non-printable geometry.
• Check scale and orientation before exporting to 3MF.
• Review material and color assignments, as not all properties may transfer perfectly.
