3D printed Mars simulant




















These small-scale structures have been 3D printed out of simulated Mars dust, to investigate the feasibility of one day using local materials for building on the Red Planet and other planets.

A miniature igloo and a corner wall were manufactured as examples of designs that might be required by colonists, produced from ‘JSC-Mars-1A’ – volcanic soil that has undergone careful processing to match the known composition and characteristics of martian soil.

“The material was mixed with phosphoric acid serving as a binding ‘ink’, then extruded through a nozzle and deposited in successive layers,” explains Christoph Buchner of Fotec, the research arm of the University of Applied Sciences in Wiener Neustadt, Austria, which performed the test project for ESA....

Considered the third industrial revolution among manufacturers, 3D printing builds a solid object from a series of layers, each one printed on top of the last – also known as additive manufacturing.

Almost anything that can be designed by computer can be printed as a physical item, typically by melting powder or wire materials

ESA and the European Commission have embarked on a project to perfect the printing of space-quality metal components. The AMAZE project – Additive Manufacturing Aiming Towards Zero Waste & Efficient Production of High-Tech Metal Products – involves 28 industrial partners across Europe......   Next
