IGES → 3MF

Convert IGES to 3MF

Turn an IGES CAD model into a 3MF mesh. Curved surfaces are meshed finely enough to stay smooth, and the part keeps its real size and orientation.

What is IGES?

IGES is an older CAD exchange format that stores exact curves and surfaces. Many machines, CAM systems and older CAD packages still expect it.

Full name
Initial Graphics Exchange Specification
Type
Exact CAD geometry
Used in
Mastercam, Rhino, SolidWorks, CATIA, older CAM software
Strength
Accepted by legacy CAD and CAM tools.
Limits
Older than STEP; solids are often stored as loose surfaces.

What is 3MF?

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.

Full name
3D Manufacturing Format
Type
Triangle mesh
Used in
Bambu Studio, PrusaSlicer, Cura, Windows 3D Viewer, OrcaSlicer
Strength
Keeps units and multiple parts; smaller than STL.
Limits
Not used by CAD or game software.

Good to know

IGES 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.

Questions

Will curves look faceted?

No. Curved faces are meshed with a tight tolerance, so holes and fillets stay smooth.

Does it keep the size of my part?

Yes. The mesh has the same dimensions as the CAD model.

Are my files uploaded?

No. Everything runs in your browser.
