Abstract: A 3D printing system includes a tank containing a liquid photopolymer resin. A textured surface is connected to the tank. The textured surface is configured such that light passes therethrough and into the liquid polymer resin. A transducer is connected to the tank. The transducer is configured to emit an acoustic wave toward the textured surface.
