Turn a BREP CAD model into a 3MF mesh. Curved surfaces are meshed finely enough to stay smooth, and the part keeps its real size and orientation.
Drop it on the converter above or click browse. It opens in your browser, so nothing is uploaded.
3MF is already selected. You can switch to any other output from the menu.

BREP is the native exact-geometry format of the OpenCascade kernel, used by FreeCAD, CadQuery and many engineering tools built on it.
3MF is the modern 3D printing format from the 3MF Consortium. Unlike STL it records units, colours and multiple objects in one compressed file, and it is the native project format of Bambu Studio and PrusaSlicer.
BREP stores exact surfaces; 3MF needs triangles. We mesh each surface with a deviation of 0.05% of the part's size, which keeps holes and fillets smooth for printing and rendering.
Dimensions stay in the units of the original file, usually millimetres.
No. Curved faces are meshed with a tight tolerance, so holes and fillets stay smooth.
Yes. The mesh has the same dimensions as the CAD model.
No. Everything runs in your browser.
