3D printing, a technology that recently went viral in the DIY community, will now be studied for printing a Moon base.
3D printing is an additive process, where successive layers of material are deposited to generate a desired shape. Recent advances in 3D printing technology have made 3D printers affordable, and the DIY community has even made many printers which can be built at home. ESA and design group Foster+Partners are studying the concept of 3D printing for construction of a Moon base, utilizing the lunar soil (regolith) as a printing material.
“3D printing offers a potential means of facilitating lunar settlement with reduced logistics from Earth,” Scott Hovland of ESA’s human spaceflight team said. “The new possibilities this work opens up can then be considered by international space agencies as part of the current development of a common exploration strategy.”
According to the researchers, the base will resemble a foam-like arrangement similar to biological structures found in nature. A part of the moon base has already been modeled, using a mixture of silicon, aluminum, iron, calcium, and magnesium oxide to simulate regolith.
Foster+Partners has designed a four-person Moon base built out of lunar regolith. As the design will utilize in-situ materials, this would significantly reduced transport cost of materials over alternative options.
“The planned site for the base is at the Moon’s southern pole, where there is near perpetual sunlight on the horizon,” officials for Foster+Partners said in a statement.
Already experimenting with guns, sculptures, cars, and now a moon base, 3D printing still has many unexplored applications, and offers a variety of benefits compared to other manufacturing techniques, both on Earth and in space. Parallel to ESA, NASA along with Washington State University are also studying 3D printing as the basis for constructing a lunar base.
These agencies are not the only ones exploring 3D printing applications in space. The company Made in Space is predicated on this technology. In the TEDx talk below, Made in Space President and Co-founder Jason Dunn discusses using 3D printing to colonize space using structures that can’t be built any other way.
