Abstract
A subwavelength resonator for acoustophoretic printing comprises a hollow resonator body for local enhancement of an acoustic field integrated with a nozzle body for delivery of an ink into the acoustic field. The nozzle body has a first end outside the hollow resonator body and a second end inside the hollow resonator body, and includes a fluid channel extending between a fluid inlet at the first end and a fluid outlet at the second end. The fluid channel passes through a side wall of the hollow resonator body and includes at least one bend. During acoustophoretic printing, an ink delivered through the fluid channel of the nozzle body and out of the fluid outlet is exposed to a high-intensity acoustic field.
