Over het STL-formaat
STL is the veteran format of 3D printing: the model is described by triangles alone, with no color, materials or layers. That is exactly why every slicer and every printer understands it, from a home machine to an industrial one.
A map is exported to STL when the city has to be held in your hands: a model of a block, a gift with your home district, a teaching aid, a stand, a blank for an architectural presentation.
What is in the file: buildings only. Each one is extruded to its own height (the height tag, otherwise the number of floors, otherwise 9 meters — about three storeys), and pitched roofs are reconstructed from OSM tags: gabled, hipped, pyramidal, mono-pitched. Where there are no tags, the shape is chosen by the type and the size of the house. Under the model lies a solid base plate so the model stands level and prints without supports under every house.
The scale is natural, in meters: before printing, shrink the model in the slicer down to the size of your bed. The terrain itself is not part of this file — the houses stand on a plane; print the relief separately: the 3D Terrain format (terrain-mesh) delivers the Copernicus GLO-30 surface as the same kind of STL, and Elevation Model (dem-geotiff) gives the raw heights — both are linked below among the related formats. The file is binary, which is several times more compact than the text variant.
Welk programma opent STL-bestanden
De volgende programma's en toepassingen kunnen STL (3D Printing)-bestanden (.stl) die uit OSM2CDR zijn geëxporteerd openen, bewerken en verwerken:
Format specifications
- Open standard
- 3D coordinates supported
- Lossless (no quality loss)
- No attributes
- Output: 1 file
- Binary STL. Buildings extruded to 2.5D height. Units: meters (scale 1:1). Opens in Blender, Meshmixer, Cura, PrusaSlicer for 3D printing. The ground under buildings is flat (z = 0): terrain is not applied — use the separate Terrain Mesh format for relief.

Openen na de export
- PrusaSlicer or Cura (free) — open the file, fit it to the bed by scaling and slice; supports are usually not needed, the model already stands on a plate.
- Blender or MeshLab — look at the model, cut off what you don't need, merge it with other objects before printing.
- Mesh checking — run the model through the check in your slicer or in Meshmixer: OSM data contains buildings overlapping each other, which produces self-intersections.
- Printing through a service — upload the file to a printing platform, where you will also see the price and get help choosing the material.
- Printing a whole city is not worth it: the file grows and the houses become indistinguishable — take a block, the center or a recognizable fragment.
