|On-Site Speaker (Planned)
This research work presents a novel drop-on-demand (DoD) technology for the spatially controlled deposition of high-temperature droplets of molten metal for the production of 3D objects in both single and multiple high temperature metallic materials. The key aspects of the printing process will be presented. Firstly the authors will discuss the stability of the jetting of two example materials, namely tin and silver. It will then be shown that by jetting metal droplets on a movable substrate with 5micron positional accuracy, it is possible to realise accurate tin and silver 2D structures. The adhesion of the droplets on the target substrates (Cu and dielectric materials) and the drop-on-drop bonding of tin and silver will be then discussed. Finally, it will be shown that by printing multiple different layers, complex, low to medium volume 3D structures for a wide variety of applications can be created.
