| Abstract Scope |
Copper is well-known for its exceptional electrical and thermal conductivity, making it essential in various industries especially high-efficiency heat exchangers. However, producing pure copper components from powder presents challenges, mainly due to its oxidation at relatively low temperatures. Gas atomization is commonly used to manufacture metal powders for AM, including binder jet printing, where particle morphology plays a crucial role. However, this method requires significant investment, and oxidation is a concern, especially for oxygen-sensitive metals.
DirectPowder™ offers a cost-effective alternative, using mechanical machining to convert copper rods into fine powders with a D50 particle size about 47 m. This approach eliminates additional oxidation during manufacturing. Despite its potencies, there is currently no research on the binder jetting and sintering processes for this powder, nor on the densification mechanisms of copper components made from such irregular particles. This study will explore these factors in copper samples produced via BJP using DirectPowder™. |
