| Abstract Scope |
Additive manufacturing, or 3D printing, enables fabrication of complex components by building parts layer by layer directly from digital designs. Among its techniques, Laser Powder Bed Fusion (LPBF) is widely used for producing high-performance metallic components, particularly alloys such as Inconel 718. In LPBF, thin layers of powder are selectively melted using a laser, and the final part quality strongly depends on process control. This study investigates the effects of key parameters including laser power, scanning speed, powder layer thickness, and powder spreading on the microstructure and mechanical properties of Inconel 718. By systematically varying these parameters, we analyze their influence on melt pool dynamics, microstructural evolution, and mechanical properties. The objective is to identify optimized parameter windows that enhance part quality and to provide deeper insight into process–structure–property relationships for reliable LPBF manufacturing of Inconel 718 components. |
