Abstract
A three-dimensional (3D) printing system includes a build vessel, a build plate, a vertical movement mechanism, a lower light engine, an upper light engine, and a controller. The build vessel is configured to contain a column of photocurable liquid above a transparent sheet. The vertical movement mechanism is configured to vertically position the build plate. The controller is configured to operate the vertical movement mechanism, the lower light engine, and the upper light engine to fabricate: (a) a lower 3D article upon a lower surface of the build platform by selective solidification of the photocurable liquid at the lower build plane using the lower light engine, and (b) an upper 3D article upon an upper surface of the build platform by selective solidification of the photocurable liquid at the upper build plane using the upper light engine.
