| Abstract Scope |
Powder-fusion based metal additive manufacturing (AM) is gaining widespread adoption across industries, with material efficiency (especially powder utilization) becoming a critical concern. A substantial portion of metal powder remains unused and is often discarded due to severe oxidation, impacting both sustainability and cost-effectiveness. Oxygen pickup is a well-known issue in Ti powders during AM, as the reuse of oxidized powder can degrade material properties and pose safety risks. This study investigates a low-temperature deoxidation-in-solid-state (DOSS) chemical method to reduce oxygen concentration in reused Ti powders, making future industrial scaling more feasible. This study explores the use of “greener” acids for pickling at room temperature and low concentrations. This project aims to push a significant advancement, particularly by enabling on-site powder recycling near AM facilities, drastically reducing waste and logistics costs while aligning with sustainable manufacturing principles. |
