Abstract

See full text

Methods and systems for producing a structure having selectable piezoelectric properties via additive manufacturing. Such methods can include coupling an ultrasound generating device to a print head of the additive manufacturing apparatus; transmitting acoustic energy from the ultrasound generating device to the print head to vibrate the print head in an oscillatory manner; extruding a feed material from the print head; moving the print head in at least one dimension relative to a substrate on which the structure is being manufactured; and dispensing layers sequentially on top of each other to form the structure. Such systems can include an additive manufacturing apparatus comprising a print head movable in at least one dimension relative to a base configured to support the structure being produced; and an ultrasound generating device that is connected to the print head.
