Abstract
A three-dimensional (3D) printing system is configured to manufacture a three-dimensional 3D article in a layer-by-layer manner. The 3D printing system includes a resin vessel, a tank agitation subsystem, a fabrication subsystem, and a controller. The resin vessel is configured to contain photocurable resin and has a lower region within a distance H of a bottom surface of the resin vessel. The agitation subsystem includes (a) a grating disposed within the lower region of the resin vessel and (b) an agitation movement mechanism coupled to the grating. The fabrication subsystem is configured to form the 3D article by a layer-by-layer selective curing of the photocurable resin. The controller is configured to operate the agitation movement mechanism to oscillate the grating along a lateral Y-axis to remix filler particulates within the photocurable resin.
