Thanks to experiments conducted by scientists at the University of Central Florida (UCF), future astronauts will be able to use bricks made from the topsoil of the Moon and salt water to build a permanent settlement base. Ranajay Ghosh, assistant professor in UCF’s Department of Mechanical and Aerospace Engineering, discovered Bricks 3D printed from dust and rocks from the Moon’s surface can withstand extreme conditions. They described their findings in detail in the journal International Ceramics and the university’s website on October 25.
The research team created a new type of brick by combining Inkjet 3D printing and binding technology (BJT), an additive manufacturing process in which a liquid binder is introduced into a layer of powder particles. According to Ghosh, BJT is particularly suited to ceramic-like materials that are difficult to laser melt. Therefore, this method has great potential for sustainable off-planet manufacturing, using topsoil to create building elements and structures.
In the BJT experiment, researchers used salt water as a binder and powder to replace lunar surface soil. Firstly, the BJT process of producing cylindrical bricks is called green parts, then fired at temperatures of up to 1,200 degrees Celsius so that the bricks can withstand pressure 250 million times greater than Earth’s atmospheric pressure. According to Ghosh, his and his colleagues’ research paves the way for using BJT in space for future manned missions. The discovery also shows that it is possible to produce bricks from abundant materials available in space. This is an important discovery, especially since transporting large quantities of construction materials to the Moon would be extremely expensive.
“The more we develop techniques to use the abundant topsoil, the more likely we are to establish and expand bases on the Moon, Mars and other planets in the future.”Ghosh said.
Last year, scientists at the University of Manchester also proposed using human blood and urine as adhesive agents to build houses on Mars. This, they said, would significantly reduce costs and speed up the construction of foreign colonies.
