Ever since proving that 3D printing using lunar material was possible, the ESA has been working on further investigating the technique.
After measuring how shielding with simulated lunar regolith could protect against radiation, the agency is now going to investigate another 3D printing method. Instead of using a binding liquid, harnessing concentrated sunlight to melt regolith could be another possibility.
“In reality any lunar base remains firmly on the drawing board, but each small step forward in research makes future lunar colonisation a little more feasible.”
Recently a video on the project has been released by ESA:
