| Abstract Scope |
The focus in metal additive manufacturing has mostly been on the powder-bed fusion and direct-energy-deposition techniques. Despite the amazing capabilities offered by these technologies and the significantly higher degrees of freedom that enable achieving greater shape complexities compared to conventional manufacturing, they have some limitations when it comes to multi-material printing for multi-functionality. This is besides the health and safety issues related to powder use and handling. In this work, we introduce a novel bespoke high-temperature metal multi-material droplet-on-demand technology, referred to as “MetalJet”. The system was validated for low (Sn) and high (Ag and Cu) temperature pure metals showing that it can additively manufacture complex structures from 70 micro-meter sized droplets drop-by-drop by employing Lorentz force. MetalJet was used to jet pure metals on a range of metallic and dielectric substrates. The drop-to-drop and drop-to-substrate interfaces were examined using a range of microstructural and mechanical characterisation techniques. |
