STL (3D Printing)
Open BetaΕξαγωγή κτιρίων πόλης σε μορφή STL για τρισδιάστατη εκτύπωση. Τα κτίρια εξωθούνται σε τρεις διαστάσεις χρησιμοποιώντας δεδομένα ύψους από ετικέτες OSM. Δυαδικό STL για συμπαγή αρχεία, έτοιμα για εισαγωγή στο slicer.

Σχετικά με τη μορφή STL
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.
Ποιο πρόγραμμα ανοίγει αρχεία STL
Τα ακόλουθα προγράμματα και εφαρμογές μπορούν να ανοίξουν, να επεξεργαστούν και να εργαστούν με αρχεία STL (3D Printing) (.stl) που έχουν εξαχθεί από το OSM2CDR:
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.
Ποιοι χρησιμοποιούν χάρτες STL
Πώς να εξαγάγετε STL
Πώς να το ανοίξετε μετά την εξαγωγή
- 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.
