Abstract Scope |
The increased freedom to design in Laser Powder Bed Fusion (LPBF) has catered to the need for lowering material usage and weight of parts in various industries including the biomedical industry through the introduction of lattice-architectured metamaterials. Though their macro-mechanical properties are extensively studied, often issues pertaining to the quality such as a higher percentage of sintered particles, higher roughness, and poor definition are overlooked. These issues contribute to a host of biocompatibility issues. This work aims to critically analyze the L-PBF thin Ti6Al4V struts manufactured at varying diameters and angles of inclination, using both continuous and pulsed modes of laser irradiation. The physics of solidification which results in the resultant surface quality is explored with the help of surface analysis and correlating it to their micro-structural features with a motivation to identify the effect of laser irradiation mode on part quality. |
