The European Space Agency’s moon brick

The age of space living may be upon us as the European Space Agency (ESA) has just announced new developments in what looks to be the future of space colonization. Following NASA’s innovations in 3D printed chainmail and their 3D printed moon village that’s set for 2030, the ESA has brought forward a new development of a brick that is printed thanks to moon dust and the sun.

Made from a commercial simulated lunar soil, researchers used a 3D printer table that includes 147 curved mirrors, which focus sunlight onto a high-temperature beam that then melts the lunar soil into thin layers. Although the solar furnace runs at a temperatures of 1,830° F (1000° C), the process itself isn’t quick, taking about 5 hours in total. At the end of the process, we are left with a solid brick that could potentially be the foundation of our future moon home.

The original goal in creating these bricks was for use in space, but with the results that they have received, researchers believe that this system could also be used here on earth to 3D print using solar power. Tommaso Ghidini, the head of the ESA’s Materials and Process division explains that “3D printing civil structures using solar power and in-situ resources could support rapid construction of post-disaster emergency shelters, removing long, costly and often inefficient supply chains.”
