The location effect on IN625 fabricated by the laser powder bed fusion process

Laser Powder Bed Fusion (L-PBF) has emerged as a transformative additive manufacturing technique, enabling the production of components with complex geometries and advanced material properties. This study investigates the processing of Inconel 625 through LPBF, focusing on enhancing porosity control and mechanical performance. The research employed commercially available Inconel 625 powder and various parameters, including laser power, scanning speed, and layer thickness, were considered to achieve defect-free structures. Vickers hardness, porosity analysis, and metallographic etching were used to evaluate the mechanical properties and microstructural characteristics of the printed samples. The results demonstrated an average porosity of 0.12%, with the smallest pores dominating the microstructure.
