| Abstract Scope |
To ensure mission success, in-situ resource utilization (ISRU) is critical to provide raw materials and manufacturing methods for the habitation of Mars. Ionic liquids (IL) are studied at NASA’s Marshall Space Flight Center (MSFC) to harvest elemental metals from regolith and meteorites, as well as a life support system, due to the efficient extraction of elements with low energy utilization. The Bosch process is also investigated at MSFC as a life support system for oxygen regeneration, producing a byproduct carbon. In this study, a steel powder was synthesized to simulate the alloying of IL-harvested iron and Bosch carbon to evaluate the IL-steel as feedstock for laser-based additive manufacturing (AM). Matrices of printing parameters were used to develop a baseline parameter set for IL-steel AM products. Samples were investigated to determine bulk density, microstructural characteristics, and hardness, with results showing the IL-steel could be a viable source for Martian surface AM. |
