Abstract

Contactless dosing of minute amounts of molten metals in the form of micron sized droplets is a promising technology with applications in the area of three dimensional printing (3DP) and electronics manufacturing. However the generation of droplets of higher melting point metals, such as aluminum and its alloys, has proven to be a challenging task. Difficulties arise mainly due to the high temperatures needed to get the metal into its liquid state and the inherent chemical aggressiveness of fluids like molten aluminum with its high reduction potential. Those conditions preclude the use of most of the common drop-on-demand (DoD) operating principles for the generation of metal droplets.
