Abstract
In this study, we examined the impact of process parameters on the manufacturing defects in micro-strut lattice structures produced via Laser Powder Bed Fusion (L-PBF). By intentionally varying parameters like laser power and layer thickness, we investigated how these changes affect internal pores, surface roughness, and geometry discrepancies. To quantify these defects, micro-CT (Computed Tomography) scanning analysis was utilised. Our findings demonstrate that manufacturing defects in lattice structures are highly sensitive to variations in process parameters. The results of this study shed light on how process parameters can be adjusted to improve the quality of micro-strut lattice structures.
