Abstract

A three-dimensional printing system includes a build vessel, a build platen, a transparent fluid, a photocurable fluid, a first fluid source, a light engine, and a controller. The transparent fluid is vertically bounded between a transparent plate and a build plane. The photocurable fluid vertically bounded between the build plane and an upper fluid surface. The controller is configured to: (1) operate the first fluid source to lower the build plane with an average velocity V by extraction of the transparent fluid from the build vessel; (2) concurrent with operating the first fluid source, operate the light engine to lower a focal plane of the light engine at the average velocity V; and (3) concurrent with operating the first fluid source, operate the light engine to selectively irradiate the build plane and to accrete the 3D article in a downward direction by the average velocity V.
