| Abstract Scope |
As the race to establish a sustainable human presence on Mars continues, the need for energy efficient, low-waste manufacturing techniques remains a major hurdle. Launching building materials from Earth is not feasible financially; therefore, in-situ resource utilization (ISRU) methods are required to ensure the success and longevity of Martian habitats. Ionic liquids (IL) are currently studied at NASA’s Marshall Space Flight Center (MSFC) to harvest metallic elements from regolith and meteorites. IL technology provides a low-temperature method to extract critical manufacturing materials, such as iron (Fe), that can be used for structures, plumbing, and tools. In this study, IL-sourced Fe (IL-Fe) was used as feedstock for selective laser melting (SLM) to obtain a baseline of material characteristics for extraterrestrial additive manufacturing. Produced samples were investigated by microstructure, hardness, and chemical composition analyses. In-situ sourced IL-Fe showed potential as a feedstock for production of metallic materials via laser-based additive manufacturing technique. |
