  • Patent number: 11654625
    Abstract: The present disclosure describes an apparatus for additively manufacturing a three-dimensional object. The apparatus includes a radiation source, a carrier on which the three-dimensional object is made, an applicator assembly configured to apply a polymerizable liquid, and a frame, with the applicator assembly and the radiation source connected to the frame. A first drive assembly interconnects the applicator assembly and the frame and a second drive assembly interconnects the carrier and the frame. The frame defines a build region between the applicator assembly and the carrier. The applicator assembly includes a polymerizable liquid supply chamber, an application roller, and a metering roller. The applicator assembly may optionally include a post-metering roller. An apparatus comprising a first and a second applicator assembly and a smaller scale version of the apparatus are also described.

  • Publication number: 20230150189
    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.

  • Patent number: 11376787
    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.

  • Publication number: 20200398480
    Abstract: A method of making a three-dimensional object includes: (a) providing an apparatus comprising a radiation source, a carrier, and a movable belt positioned therebetween, with the belt comprised of an optically transparent material, and with the belt permeable to a polymerization inhibitor; (b) applying a polymerizable liquid to a first surface of the belt, and contacting a second surface of the belt to the polymerization inhibitor, (c) contacting a portion of the first surface to the carrier or the three dimensional object so that the belt adheres thereto with the polymerizable liquid positioned therebetween; (d) irradiating the polymerizable liquid with actinic radiation through the belt from the radiation source to polymerize the polymerizable liquid positioned therebetween; then (e) optionally separating the belt from the carrier or the three dimensional object; and then (f) repeating steps (b) through (e) until the three dimensional object is completed.
