Laser powder-directed energy deposition of lunar highlands regolith simulant in argon and vacuum environments: Effects of atmosphere on microstructure

Additive Manufacturing Letters
Additive manufacturing (AM) of lunar regolith offers a potential pathway for in-situ resource utilization (ISRU) on the Moon, but the limited understanding of how the extreme conditions of the lunar environment influence processing approaches has limited
