1. A subwavelength resonator for acoustophoretic printing, the resonator comprising:
a hollow resonator body for local enhancement of an acoustic field; and
a nozzle body integrated with the hollow resonator body for delivery of an ink into the acoustic field, the nozzle body having a first end outside the hollow resonator body and a second end inside the hollow resonator body, the nozzle body comprising a fluid channel extending between a fluid inlet at the first end and a fluid outlet at the second end, the fluid channel passing through a side wall of the hollow resonator body and including at least one bend.
