| Abstract Scope |
In drop-on-demand metal jetting, molten metal droplets are dispensed and deposited at precise locations to fabricate functional objects. This emerging technology opens new opportunities to produce intricate metallic components. MetalJet, the novel technique introduced in this study has the capacity to produce molten microdroplets (~70 µm) of high-temperature metals (up to 2000 °C) to form single and multi-material objects. Numerous applications, such as flexible circuits, advanced electronic components and biotechnologies, are considered using MetalJet. However, the full exploitation of the technology is impeded by the lack of knowledge on the fundamental physical phenomena occurring during the printing process. These consist of the level and nature of droplet bonding to the substrate, inter-droplet bonding, the residual stresses built-up, deformations, and the final microstructure of the printed parts. This study uses an integrated computational and experimental approach to provide insights that address these remaining questions. |
