| Abstract | In this work, we present a novel generation of pneumatically actuated printheads based on the StarJet technology which have been successfully applied for the direct non-contact printing of droplets from molten metal [1, 2]. This paper reports the technological advances of the newly designed printhead V3 which for the first time has been fabricated by selective laser melting (SLM). The StarJet technology features an inert rinse gas that surrounds the droplets inside the nozzle. V3 features an integrated heating for rinse gas which prevents the droplets from fast solidification and oxidation after ejection, as they are surrounded by hot nitrogen gas. The feasibility of the StarJet technology is demonstrated for printing at temperatures up to 500 °C. Moreover, the angular deviation of the droplets' flight path has been investigated. A maximum angular deviation of 0.89° has been evaluated. The droplets' velocity after ejection and the influence of the different pressures on this parameter have been investigated. |
