3D printing with Mars dirt and titanium

Washington State researchers add to out-of-this-world 3D printer materials

Scientists from Washington State University have discovered that a small amount of simulated crushed Martian dirt mixed with a titanium alloy made for a stronger, high-performance material for 3D printing that could help build a future on the Red Planet.

"In space, 3D printing is something that has to happen if we want to t...
