Abstract

See full text

A method of acoustophoretic printing comprises generating an acoustic field at a first end of an acoustic chamber fully or partially enclosed by sound-reflecting walls. The acoustic field interacts with the sound-reflecting walls and travels through the acoustic chamber. The acoustic field is enhanced in a chamber outlet at a second end of the acoustic chamber. An ink is delivered into a nozzle positioned within the acoustic chamber. The nozzle has a nozzle opening projecting into the chamber outlet. The ink travels through the nozzle and is exposed to the enhanced acoustic field at the nozzle opening, and a predetermined volume of the ink is ejected from the nozzle opening and out of the acoustic chamber.
