Simulated Mars dust makes for weird 3D-printed objects

When humans finally get to Mars, they’ll need to use local resources in their quest for survival. Mars has a lot of dust, and the European Space Agency is looking at how to transform it into useful 3D-printed objects. On Wednesday, the ESA posted the fascinating results of a 3D-printing test using simulated Mars soil on Wednesday.

The team 3D-printed an igloo-like structure and a wall corner. They’re sized for a small mouse, but they show that it’s possible to create sturdy objects using the local resources on Mars.

The researchers used a Mars soil simulant called JSC-Mars-1A, which contains volcanic material, mixed with phosphoric acid as a binder. The mixture was extruded through a nozzle and layered in typical 3D-printing fashion.

The igloo and corner won’t win many points for aesthetics, but that’s OK.
