Manufacturing on Mars with 3D Printing

A small amount of simulated crushed Martian rock mixed with a titanium alloy made a stronger, high-performance material in a 3D-printing process that one day could be used on Mars to make tools or rocket parts. The parts were made by Washington State University researchers with as little as 5 percent up to 100 percent Martian regolith, a black powdery substance meant to mimic the rocky, inorganic material found on the surface of Mars.
