Convert 3DS to 3MF
Convert a 3DS file to 3MF in your browser. Free, no upload, no sign-up.
Convert 3DS files to 3MF directly in your browser. The converter parses the 3DS 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 3DS to 3MF
- 1Drop your 3DS file
Drag a .3ds file onto the box above or click to choose one. Mesh geometry is read; textures and lights are ignored.
- 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 3DS file?
3DS is the binary format of the original Autodesk 3D Studio from the DOS era. It is limited to 65,536 vertices per object and 8-character names, yet an enormous number of models from older libraries and marketplaces are still shipped as .3ds files.
Commonly used by: legacy 3ds Max scenes, old model marketplaces

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
