Abstract
A three-dimensional printing system for manufacturing a three-dimensional article includes a transparent substrate, a fluid handling system, a support tray, and a light engine. The transparent substrate slopes downwardly from an upper end toward a lower end. The fluid handling system is configured to input photocurable resin at the upper end and to receive the photocurable resin at the lower end. The fluid handling system thereby forms a gravity-driven flowing sheet of resin over an upper surface of the transparent sheet. The support tray is mounted to a movement mechanism. The support tray has a lower face for supporting the three-dimensional article. The lower face is generally parallel to the upper surface of the transparent substrate. The light engine is positioned below the transparent substrate for selectively illuminating the resin along a build plane that is within the resin and parallel to the upper surface of the transparent substrate.
