Abstract: A three-dimensional printing system includes a resin vessel containing resin, an imaging bar, a movement mechanism coupled to the imaging bar, and a controller. The imaging bar includes an arrangement of light emitting devices that selectively emit radiation from an exit surface of the imaging bar to define a build plane in the resin. The exit surface of the imaging bar is preferably less than 10 millimeters from the build plane. The controller is configured to scan the imaging bar along a scan axis and, concurrent with scanning, operate the imaging bar to selectively image a layer of resin at the build plane.
