Popis: Many parameters in a laser based powder bed fusion process affect the part property. In this research, experiments were designed to study how scanning pattern affects the properties of printed 17-4 PH stainless steel parts. Five different representative scanning patterns were adopted. Micro hardness, density and energy consumption values of the sample parts were analyzed. Micro hardness was evenly distributed, and above the standard hardness value. Hardness in cross section is generally higher than that in vertical section. Density of parts in concentric line pattern is the lowest, and continuous mesh is the highest. Using continuous mesh, it consumed more energy than others.
