Moon-Based 3-D Printers Could Create Tools From Lunar Dust

Washington State University researchers made these cylinders on a 3-D printer using simulated moon rock. The technology would help lunar travelers make tools and repairs with materials found on the moon.

This tool was repaired using material 3-D printed from simulated moon dust. When laser-heated, the dust melts and rejoins the parts.
