3MF to DXF Converter
Drop a .3mf file below and get a .dxf back. The conversion happens inside this page using WebAssembly, so nothing is uploaded to a server and there is no queue to wait in.

How to convert 3MF to DXF
- 1Add your 3MF fileDrop the .3mf file into the box, or pick it from disk. Multiple files are converted one after another.
- 2Pick DXF as the outputDXF is already selected on this page. Adjust scale, up axis or triangle budget if the target application is picky.
- 3Download the resultThe .dxf file is written locally and appears as a download button next to your file.
About 3MF
3MF is a zipped XML package that fixes what STL never had: real units, colours, materials, multiple objects and print metadata. Every current slicer reads it and it is the default in Bambu Studio and PrusaSlicer.

About DXF
DXF is the published counterpart to AutoCAD's DWG. It is mostly used for 2D drawings, but the 3DFACE entity carries triangulated surfaces, so meshes can be handed to CAD and CAM tools that never learned to read mesh formats.
- DXF is supported as an output only. Meshes are written as 3DFACE entities, one per triangle.

Questions
Is this 3MF to DXF converter free?
Yes. There is no account, no daily quota and no watermark. The tool is a static web page and the work is done by your own CPU, so there are no server costs to pass on.
Are my files uploaded anywhere?
No. MeshFormat loads a WebAssembly build of the geometry kernels into your browser and reads the file locally. You can open the network tab and confirm that nothing leaves the page, or disconnect after the page has loaded and keep converting.
How large can a 3MF file be?
The practical limit is your available memory rather than an arbitrary cap. Models up to a few hundred megabytes work on a normal laptop; very dense scans convert faster if you lower the triangle budget in the options.
What is lost when converting 3MF to DXF?
Vertex colors: vertex colours are dropped because the output format has nowhere to store a colour per vertex. Materials: material definitions are dropped, so the model arrives with a single neutral surface.
Anything to know about DXF output?
DXF is supported as an output only. Meshes are written as 3DFACE entities, one per triangle.
Which programs open DXF files?
AutoCAD, BricsCAD, LibreCAD, Fusion 360 and most other tools that work with CAD data read .dxf directly.
