Abstract
The present disclosure describes an additive manufacturing apparatus. The apparatus includes a chamber () having a planar circumferential top edge portion () defining a chamber orifice (); a stage () movably positioned in the chamber (), the two together configured to receive a viscous resin; a dispenser () facing the stage () and operatively associated therewith, the dispenser () configured to apply a planar coating of viscous resin; a primary drive () operatively associated with the dispenser () and chamber (), the primary drive () configured to move the dispenser () across the chamber orifice (); a light engine () facing the stage () and operatively associated therewith, the light engine () configured to expose a coating of resin on the stage () planar top surface () to patterned light; and a stage drive () operatively associated with the stage () and configured to retract the stage () into the chamber (), following exposure of a coating of resin. Methods of making a three-dimensional object by additive manufacturing are also described.
