Printing tips for Valles Marineris

Planet-scale areas print almost flat at true scale, so the model starts at 4× vertical exaggeration: raise it for broad basins, lower it for steep volcanoes.
A 150–200 mm print fits most printers; for bigger displays, use multi-tile mode and print it in pieces.
Print at 0.12–0.16 mm layer height for smooth slopes and fine ridges, with 10–15% infill.
A single grey, rust or sand-coloured filament suits it best; print a small test piece first to check the exaggeration.

Questions

Is the Valles Marineris 3D model free?

Yes. TerraPrinter is free with no account needed: generate the model in your browser and download it as STL, 3MF, GLB or OBJ.

Which file format should I use for printing?

STL works with every slicer. 3MF keeps terrain, water, roads and buildings as separate colored parts, which is ideal for multi-color printers.

How big will the print be?

You choose: the default is 200 mm on the longest side. Larger models can be split into tiles or jigsaw puzzle pieces that fit your print bed.

Where does the terrain data come from?

Elevation comes from the HRSC and MOLA blended Mars elevation model (200 m resolution) by NASA, ESA/DLR and the USGS Astrogeology Science Center, served from TerraPrinter's own map server.
