Abstract: A three-dimensional printing system is provided that includes a tank, a textured substrate connected to the tank, and a reservoir. The tank contains a liquid photopolymer resin. The textured substrate is configured to allow light to pass through into the liquid photopolymer resin. The reservoir contains lubricant and is formed around a perimeter of the tank. The reservoir is connected to the textured substrate and configured to supply the lubricant to the textured substrate.
