Abstract: Provided herein are methods of making imaging systems. In one aspect, the method may comprise providing a lens; providing an optomechanical assembly; providing an imaging sensor; and operably connecting the optomechanical assembly with said lens and said imaging sensor, forming said imaging system. In some aspects, providing an optomechanical assembly may comprise manufacturing a component of the optomechanical assembly using additive manufacturing. In some aspects, providing an optomechanical assembly may comprise manufacturing a component of the optomechanical assembly using micro-continuous liquid interface production (μCLIP) 3D printing.

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.

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.
