| Abstract Scope |
Additive manufacturing has transformed the production of complex components, particularly in applications demanding customization, intricate geometries, and material efficiency. Integrating this technology with lunar exploration offers promising advantages for future space missions. This study investigates the effects of lunar regolith on the microstructure and mechanical properties of stainless-steel parts fabricated using Wire-Laser Directed Energy Deposition (WL-DED). Specifically, we examine how the presence of regolith influences bead geometry, grain structure, hardness, and overall structural integrity. Single-track lines, multi-layer cubes, and tensile coupons were printed under controlled parameters. The resulting microstructures were characterized, and mechanical properties such as hardness and tensile strength were evaluated. Our findings aim to assess the feasibility of incorporating lunar regolith into the WL-DED process as a step toward in-situ resource utilization on the Moon. This research contributes to supporting sustainable and efficient manufacturing methods for future lunar infrastructure. |
