Summary

This paper explores the application of laser-based manufacturing techniques in space, focusing on two key methods: Laser Powder Directed Energy Deposition (LP-DED) in microgravity and Powder Bed Fusion (PBF) using lunar regolith. The study highlights the experimental setup and results from the Einstein-Elevator experiment, which simulated microgravity conditions to test LP-DED. Additionally, it outlines the initial steps toward realizing PBF-LB (Lunar Bed) using lunar regolith, emphasizing the potential for in-situ resource utilization on the Moon. The paper concludes with future outlooks for in-space manufacturing and its implications for space exploration. The paper discusses the application of laser powder directed energy deposition and substrate-free single layer powder bed fusion under microgravity and lunar gravity conditions. It presents experimental setups, including the Einstein-Elevator, and evaluates the effects of different gravity levels on specimen manufacturing, surface temperature, induced acceleration, microstructure, hardness, and density. Computed tomography and laser scanning strategies are used for analysis. This paper discusses laser-based in-space manufacturi
