Abstract
A three-dimensional (3D) printing system for manufacturing a 3D article includes a resin vessel, a build tray, a movement mechanism, a light engine, a housing, a gas handling system, and a controller. The resin vessel includes a transparent sheet on a lower side. The housing defines two chambers including an upper chamber and a lower chamber. The upper chamber is in fluidic communication with the resin contained by the resin vessel. The lower chamber is in fluid communication with a lower surface of the transparent sheet. The controller is configured to (a) operate the gas handling system to reduce and control a partial pressure of oxygen in the upper and lower chambers, (b) operate the movement mechanism and the light engine to form the 3D article in a layer-by-layer manner.
