| Abstract Scope |
Copper, known for its excellent electrical and thermal conductivity, is extensively used in various industries. However, producing pure copper components from powder has unique challenges, notably its tendency to oxidize. The evolution from traditional cold compaction to additive manufacturing (AM) techniques has marked shift, leading to more efficient and flexible production that offer greater freedom of design and a wider array of applications in copper manufacturing. Despite these advancements, significant problems remain. Copper's high reflectivity promotes research in AM methods compensating for the lower energy absorption e.g. by using blue diode lasers or electron beams. Binder jet printing (BJP), as a solid-state AM method, faces other issues such as impurities from binder residues and oxidation during sintering. Here, we present microstructures and properties of BJP and sintered copper powder manufactured via an alternative powder manufacturing method and compare these results to other Cu powder metallurgy manufactured parts. |
