| Abstract Scope |
Cu is the second most conductive element. This high conductivity in addition to high reflectivity makes fabrication of Cu using laser and electron beam PBF processes very challenging. Cu is also very ductile that may not be very desirable for structural applications. The addition of CNT could increase its strength. Cu has been successfully fabricated using regular and green laser PBF. However, there is conflicting information on the optimum process parameters for achieving high density Cu. CNTs can also be used to reduce the reflectivity and increase the absorptivity of the Cu-CNT powder. This study focuses on providing an overview of literature on optimum process parameters for both laser and e-beam powder bed process for successful fabrication of Cu. It will also demonstrate a process where Cu and Cu-CNT fabrication are optimized through a physics-based analytical process and demonstrated through an experiment. |
