This paper investigates the use of laser directed energy deposition (LDED) additive manufacturing to fabricate structures from lunar highland regolith simulant LHS-1. The study examines the effects of laser power, scanning speed, and ambient conditions on microstructure formation, including mullite and augite-plagioclase phases. Results highlight the importance of substrate choice and the correlation between processing parameters and microstructural properties. The paper discusses the application of additive manufacturing techniques for the fabrication of lunar regolith-based materials, focusing on the development of functionally graded materials suitable for in-situ resource utilization (ISRU) on the Moon. The study highlights the potential of laser sintering and other advanced manufacturing methods to create structural components for lunar habitats and infrastructure. The authors also emphasize the importance of material characterization and the integration of multi-scale modeling to optimize the performance of these materials under lunar environmental conditions.
