Abstract Scope |
Insufficient access to a variety of alloy powders remains a significant challenge in additive manufacturing. This is compounded by the expensive and time-consuming validation process required to qualify reliable and reproducible alloys for 3D printing. Traditional powder production methods such as gas, plasma, centrifugal, or water atomization have drawbacks including high costs, limited material compatibility, wide particle size distribution, and minimum input requirements. However, ultrasonic atomization technology is a solution to these challenges. Presented method enables laboratory scale and cost effective in-house production of metallic powders with tailored chemical compositions. It offers a flexibility in materials selection from low melting point alloys like MgLi, through Cu, Fe, Ni based alloys up to refractories. |
