| Abstract Scope |
As humanity prepares for sustained lunar exploration, in-situ manufacturing using additive technologies offers transformative potential for reducing dependence on Earth-based supply chains. Recent advancements in wire-laser directed energy deposition (WL-DED) have sparked interest in the use of this technology on the Earth’s moon due to its reduced reliance on a strong gravitational force, as required for powder-based processes. Numerical modeling offers an effective way to simulate the solidification dynamics of DED processes, providing insights into how process parameters influence the melt pool geometry and thermal history of the part. This study investigates the simulation of WL-DED for manufacturing on the lunar surface, focusing on the challenges the lunar environment poses. Using advanced multiphysics computational models, we simulate the laser-material interaction under reduced gravity, near-vacuum conditions, and extreme thermal gradients, advancing the understanding of how process control under different environmental conditions can be used to improved material properties in additive manufacturing. |
