Abstract Scope |
Copper is the common metal used as conductors in many applications such as structural aerospace or electrical components. These applications usually require parts with complex geometry which are challenging to get using conventional manufacturing techniques. Additive manufacturing (AM) as a disruptive technology allows the production of unique and complex custom-made part. However, there are limited study on AM of pure copper, particularly for laser powder bed fusion (LPBF) approaches due to challenges associated with its high thermal conductivity. Here, we studied the feasibility of fabrication of pure copper using LPBF-AM. The process parameter including scan speed, laser power, and hatch spacing were varied to find optimum condition to obtain high quality part. The surface roughness, microstructure, density, and thermal conductivity of parts were investigated. The results showed that the bulk copper sample with surface roughness below 20 µm and relative density of > 90% was successfully fabricated using LPBF-AM technique. |
