Característiques clau
Sobre el format 3MF
3MF is an open 3D printing format from the 3MF Consortium, conceived as a replacement for STL. Inside it is a ZIP archive with an XML model, so a single file holds not only triangles but also colors, separate scene objects and metadata. Modern slicers — PrusaSlicer, Cura, Bambu Studio, Orca — read it out of the box.
A map is exported to 3MF for printing a physical model: a city district on a base, an architectural context model, a teaching aid. Compared with STL the gain is practical: buildings arrive as separate objects with colors by development type, and the slicer sees them individually instead of as one fused mesh.
The output is a single .3mf file: buildings extruded from OSM outlines by height or floor count, and a solid base plate under them so the model stands flat on the bed and needs no supports. The geometry is built in real-world meters and centered on the selected area — the final size of the model is set by the scale in the slicer.

Qui utilitza els mapes 3MF
Com exportar 3MF
Com obrir el fitxer després de l'exportació
- PrusaSlicer, Cura, Bambu Studio or Orca Slicer — File → Open/Import, then set the scale to fit your bed: the model arrives in real meters.
- Check before printing — look at the thinnest buildings: if a wall is thinner than a couple of nozzle widths, increase the scale or take a smaller area.
- 3D Builder (included with Windows) — quick viewing and editing: delete extra objects, check that the model is watertight.
- Blender or Fusion 360 — open the .3mf if the model needs finishing: trim the edges, add a caption or mounting points.
- Color printing — building colors are stored in the file, but they only come out on multi-material printing; on a single-color printer they are simply ignored.
