摘要： Systems and methods for additive manufacturing. In some examples, a system includes a frame defining an interior volume and an overhead robotic arm suspended from a gantry on a ceiling of the frame. The system includes manufacturing subsystems located within the interior volume of the frame. The system includes a control system configured for controlling the overhead robotic arm for parts movement among additive manufacturing processes using the manufacturing subsystems. The manufacturing subsystems can include one or more of: a microassembly station, an aerosol jetting print station, an intense pulsed light (IPL) photonic sintering station, a fiber weaving station, and a 3D printing station.

摘要： 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.
