Summary

This paper investigates the effect of particle size on laser beam melting (PBF-LB) of the LX-M100 lunar regolith simulant. It reports on porosity, thickness, and strength variations with particle size, and chemical composition differences between solid and pore wall materials. The study highlights the relationship between particle size, porosity, and mechanical properties in PBF-LB fabricated samples. This study investigates the influence of particle size on laser beam melting of lunar regolith simulant. The LX-M100 simulant was used in three particle size fractions. Key findings include differences in chemical composition between solid material and pore walls, effects on physical and mechanical properties, and correlations between particle size and porosity. This paper investigates the influence of particle size on laser beam melting of lunar regolith simulant LX-M100. It reports elemental composition changes in solid material and pore walls, discusses the impact of gravity and regolith composition on the process, and suggests future experiments with other simulants like LX-I50 and LX-T100. It also outlines considerations for using different particle sizes in construction applicat
