| Abstract Scope |
This work presents a new technique to generate uniform and micron-sized metal powders for advanced additive manufacturing. By collecting discrete chips resulting from ultrasonic vibration machining, we demonstrate the feasibility of generating consistent powders with tight dimensional tolerance, the ability to control powder geometry, and good efficiency. It offers a new route for sustainable and low-cost manufacturing of high-quality metal powders. The powder generation mechanism is analyzed with a special tool path design to ensure consistent dimensions over multiple cuts. Aluminum and brass powders with critical dimensions of 25 by 50 µm are demonstrated and verified with selective laser melting. |
