Abstract

A 3D printing system includes a tank containing a liquid photopolymer resin. The tank includes an optically transparent window through which light is configured to pass. A heat exchanger is connected to the tank and is configured to cool the liquid polymer resin. A transducer is connected to the tank. The transducer is configured to emit an acoustic wave toward the optically transparent window.
