Convert DXF to 3MF
Convert a DXF file to 3MF in your browser. Free, no upload, no sign-up.
Convert DXF files to 3MF directly in your browser. The converter extrudes every filled shape in the DXF to the thickness you choose and writes the resulting solid as 3MF. 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 DXF to 3MF
- 1Drop your DXF file
Drag a .dxf file onto the box above or click to choose one. Closed outlines (polylines, circles, ellipses and splines) are extruded to the depth you choose; open lines, hatches, dimensions and text are skipped. Files that already contain 3D faces are read as a mesh instead. Drawing units are taken from the file header, so an inch drawing arrives at the right size.
- 2Set the extrusion depth
Enter how thick the 3D shape should be in millimeters before dropping the file, or change it and reconvert.
- 3Check 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.
- 4Download 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 DXF file?
DXF is the open interchange format Autodesk published for AutoCAD in 1982. Most DXF files are 2D drawings: lines, arcs, polylines and text on layers. Some also carry 3D geometry as 3DFACE entities. It is what 2D CAD, laser cutters and CNC routers exchange.
Commonly used by: AutoCAD, LibreCAD, QCAD, Laser cutters, CNC routers, Fusion 360 sketches

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.
