Abstract: A method of forming a three-dimensional object is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween, with the carrier positioned adjacent and spaced apart from the build surface at a start position; then (b) forming an adhesion segment of the three-dimensional object (c) optionally but preferably forming a transition segment of the three dimensional object; and then (d) forming a body segment of the three dimensional object. In each case, the segment can be formed by: (i) filling the build region with a polymerizable liquid, (ii) continuously or intermittently irradiating the build region with light through the optically transparent, and (iii) continuously or intermittently advancing the carrier away from the build surface, to thereby form that segment from the polymerizable liquid.

Abstract: Described herein are methods and apparatus for the production of a three-dimensional object by “bottom up” additive manufacturing, in which a carrier (112) is vertically reciprocated with respect to a build surface, to enhance or speed the refilling of the build region with a solidifiable liquid. In preferred embodiments, the three-dimensional object is produced from a liquid interface by continuous liquid interface production (i.e., “CLIP”).

Abstract: A method of forming a three-dimensional object (17) includes: providing a carrier (18) and an optically transparent member (15) having a build surface, the carrier (18) and the build surface defining a build region therebetween; filling the build region with a polymerizable liquid (16); irradiating the build region with light (12) through the optically transparent member (15) to form a solid polymer from the polymerizable liquid; and advancing the carrier (18) away from the build surface to form the three-dimensional object (17) from the solid polymer. The carrier (18) includes at least one retain and release (34) feature that is configured to: i) retain the three-dimensional object (17) formed from the solid polymer on the carrier (18) in a first state; and ii) facilitate release of the three-dimensional object (17) formed from the solid polymer from the carrier (18) in a second state.

Abstract: Described herein are methods, systems and apparatus (including associated control methods, systems and apparatus), for the production of a three-dimensional object by “bottom up” additive manufacturing, in which a carrier is vertically reciprocated with respect to a build surface, to enhance or speed the refilling of the build region with a solidifiable liquid. In preferred (but not necessarily limiting) embodiments, the three-dimensional object is produced from a liquid interface by continuous liquid interface production (i.e., “CLIP”).

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. Methods of making a three-dimensional object by additive manufacturing are also described.

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 apparatus (10) for additively manufacturing a three-dimensional object. The apparatus (10) includes a radiation source (13), a carrier (1) on which the three-dimensional object is made, an applicator assembly (3) configured to apply a polymerizable liquid, and a frame (8), with the applicator assembly and the radiation source connected to the frame. A first drive assembly (4) interconnects the applicator assembly and the frame and a second drive assembly (2) interconnects the carrier and the frame. The frame defines a build region (6) between the applicator assembly and the carrier. The applicator assembly includes a polymerizable liquid supply chamber, an application roller (11), and a metering roller (12). The applicator assembly may optionally include a post-metering roller (14). An apparatus comprising a first and a second applicator assembly and a smaller scale version of the apparatus are also described.
