Abstract

Systems and methods for additive manufacturing, and, in particular, such methods and apparatus as employ pulsed lasers or other heating arrangements to create metal droplets from donor metal micro wires, which droplets, when solidified in the aggregate, form 3D structures. A supply of metal micro wire is arranged so as to be fed towards a nozzle area by a piezo translator. Near the nozzle, an end portion of the metal micro wire is heated (e.g., by a laser pulse or an electric heater element), thereby causing the end portion of the metal micro wire near the nozzle area to form a droplet of metal. A receiving substrate is positioned to receive the droplet of metal jetted from the nozzle area.
