Abstract

An aspect of the present disclosure provides a system for aerosol jet printing an aerosolized particle source configured to selectively provide aerosolized particles, a nozzle configured to deposit aerosolized particles on a substrate, an actuator configured to generate acoustic energy for migrating the particles, and a generator configured to selectively energize the actuator. The nozzle includes a proximal inlet configured for passage of aerosolized particles, a column configured to focus the aerosolized particles when vibrated by an actuator, and a distal opening configured for deposition of the particles on a substrate.
