Convert 3DM files to STL in seconds. Geometry, UVs and materials are carried over where STL supports them, and the model lands the right way up.
Drop it on the converter above or click browse. It opens in your browser, so nothing is uploaded.
STL is already selected. You can switch to any other output from the menu.
Click Convert and your STL file is ready in seconds. Download it straight away.
3DM is the native file of Rhino, used widely in industrial, jewellery and architectural design. It stores NURBS surfaces, SubD objects, meshes and block instances.
STL describes a surface as a list of triangles, with no colour, material or unit information. It is the default file for 3D printing and is exported by almost every CAD and modelling program.
Rhino saves a display mesh for every surface it has shown in shaded view. We use those meshes. If a file was saved with "Save Small", open it in Rhino, switch to shaded view and save it again.
Colours and texture coordinates are carried over when STL supports them. STL does not store textures, so only the geometry carries over.
No. 3DM and STL may use different "up" directions, and we rotate the model so it stands the same way in your software.
