Abstract
A 3D printing system includes a tank containing a liquid photopolymer resin. A textured substrate is connected to the tank. The textured substrate is configured such that light passes therethrough into the liquid polymer resin. A layer of an inert material is disposed on the textured surface. The liquid photopolymer resin and the inert material are discharged from the tank through a tank outlet. Additional liquid photopolymer resin and additional inert material are added to the tank through a tank inlet.
