Abstract: Methods of making a three-dimensional object from a light polymerizable resin are described. A method may include: (a) providing a window, a light polymerizable resin, a laterally translatable substrate between said window and said resin to which said resin is adhered, and a carrier platform above said window; (b) irradiating said resin with light through said window and said translatable substrate, and vertically advancing said carrier away from said window, to produce a growing object on said carrier platform and consume resin beneath said growing object; and (c) laterally advancing said translatable substrate with said resin adhered thereto across said window to drag fresh resin beneath said growing object, continue producing said growing object and continue consuming fresh resin, until said three-dimensional object is produced.

Abstract: The present disclosure describes an additive manufacturing apparatus. The apparatus includes a chamber (11) having a planar circumferential top edge portion (12) defining a chamber orifice (13); a stage (15) movably positioned in the chamber (11), the two together configured to receive a viscous resin; a dispenser (30) facing the stage (15) and operatively associated therewith, the dispenser (30) configured to apply a planar coating of viscous resin; a primary drive (22) operatively associated with the dispenser (30) and chamber (11), the primary drive (22) configured to move the dispenser (30) across the chamber orifice (13); a light engine (40) facing the stage (15) and operatively associated therewith, the light engine (40) configured to expose a coating of resin on the stage (15) planar top surface (12) to patterned light; and a stage drive (24) operatively associated with the stage (15) and configured to retract the stage (15) into the chamber (11), following exposure of a coating of resin.
