Given NASA’s objectives for long-term human presence and infrastructure development on the lunar surface, it is critical that the Agency develops technology and methods to utilize in-situ resources to build critical infrastructure including habitats, roadways, and landing pads. One proposed construction method is additive manufacturing (AM) of lunar regolith via a high-energy laser that fuses regolith into glass ceramics. The purpose of my internship was to develop hardware and software to begin thermal data collection of lunar regolith AM via a variety of methods, including laser powder bed fusion (LPBF) and directed energy deposition (DED), as well as develop methodology to connect thermal history to material properties. To accomplish this goal, I captured and cleaned raw data collected from both infrared and visible light cameras and processed the data by fitting thermal history into exponential trends that capture average temperature profiles across the whole process. I also designed, manufactured, and installed thermal imaging hardware rated for vacuum testing, allowing the team to collect thermal data in environments previously inaccessible. Finally, I utilized computational thermodynamic software to predict crystal formation in structures and confirmed phase formation using optical microscopy (supporting existing x-ray diffraction data). While this project is ongoing and has yet to achieve final results, and my internship ended before the hardware I developed could be tested, the scope of my contributions allows further characterization of existing materials and a better understanding of the manufacturing process for future fused regolith structures build from both LPBF and DED.
