Abstract

Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a system for reducing adhesion during cure processing for a stereolithographic 3D printed object. The system includes resin tank for maintaining a liquid photopolymer resin. The system further includes a light source. The system further includes controller for selectively exposing the liquid photopolymer resin to form a solid object in the resin tank. The resin tank is constructed of a rigid material that has an oxygen permeability that is above a first threshold so as to reduce a separation force required to remove the solid object from the resin tank after curing.
