| Abstract Scope |
Future crewed missions and eventual long-term habitation of the Martian surface will rely on the ability to produce and repair components and structures on site with materials sourced from the local environment, i.e., in-situ resource utilization (ISRU). Synergizing additive manufacturing (AM) processes with ISRU techniques satisfies these requirements while also allowing for on demand rapid prototyping and net-shape construction. Direct regolith printing of ceramics and elements harvested for metallic material feedstocks have been shown to be viable in the past, and carbothermal reduction (CR) has been a successful endeavor for oxygen (O2) generation. In this study, a metallurgical carbon (C) and Martian regolith simulant mixture was used in laser-based powder bed fusion (PBF-LB) to evaluate the application of AM and CR simultaneously. The regolith and carbon sources were characterized, and samples were constructed for x-ray diffraction (XRD) and compression testing to determine the benefits of C additives in regolith printing. |
