Abstract Scope |
Laser powder bed fusion (L-PBF) has attracted great interest in the aerospace sectors, because it can produce complex parts with high accuracy. In the L-PBF of metallic materials, costs and material yields strongly depend on the ability to reuse powder efficiently. However, some of the powders are exposed to high temperatures during the manufacturing process resulting in an alteration of the feedstock properties if it reused. Therefore, in order to investigate the change of the powder during the process and the effect of the powder on the laminated parts, we tried to investigate the effect of reused STS316L powders on the mechanical properties of their printed products under 298 and 77 K conditions. The powders were used, collected, sieved, and reused up to 6 times with all steps from the original powder. |
