Abstract: A 3D printing system includes a tank containing a liquid photopolymer resin. A textured surface is disposed in the tank. The textured surface is configured such that light passes through therethrough and into the liquid polymer resin. A layer of an inert material is disposed on the textured surface.

Abstract: An acoustic force assisted painting system has a housing, at least one nozzle and at least one acoustic emitter. The housing has a conduit for receiving paint from an external source into the housing. The at least one nozzle is disposed in the housing. The at least one nozzle has an inlet that is fluidly connected to the conduit to receive paint from the conduit. The at least one nozzle has an outlet that dispenses paint. The least one acoustic emitter is disposed in the housing at a location downstream of the inlet with respect to the conduit.

Abstract: A 3-D printer apparatus (three-dimensional printer apparatus) includes a bottom structure of a tank. The tank defines a printing area located above and spaced apart from the bottom structure. The bottom structure includes oxygen releasing electrodes. A resin curing device is configured to selectively provide light to the printing area. The electronic controller controls operation of the resin curing device and the oxygen releasing electrodes. The electronic controller selectively operates areas of the oxygen releasing electrodes thereby releasing oxygen to predetermined locations below the printing area in order to temporarily prevent the polymerization of a polymerizable resin within predetermined locations of the printing area during the printing process.
