    Abstract: A continuous liquid interface production system includes a source of optical stimulation. The system includes a vessel configured to retain a pool or film of optically sensitive monomer and a substantially optically transparent plate retained by the vessel. The optical stimulation is directed through the plate and into the pool or the film based upon a sliced 3D model of the part. The system includes source of reaction inhibitor wherein the substantially optically transparent plate allows the reaction inhibitor to permeate through the plate and into the pool or the film such that a sufficient amount of reaction inhibitor is within the pool or the film to create a zone proximate the plate that prevents polymerization therein. A build platen is configured to be at least partially immersed into the pool or the film and above the zone as a part is initially being built, wherein a build platen actuator moves the build platen away from the pool or the film in a direction substantially normal to a top surface of the plate. A relative movement actuator provides relative movement between the plate and the part in a direction substantially parallel to the top surface of the plate such that a viscosity pump effect is created that forces monomer between the part being built and the plate.

    Abstract: A pump assembly for use in an additive manufacturing system includes a viscosity pump having a first end and a second end wherein the first end has a cross sectional area greater than a cross sectional area of the second end. The viscosity pump has a conical shaped inner surface defining a pump chamber, an inlet proximate the first end and an outlet proximate the second end. The viscosity pump includes an impeller having an axis of rotation, where the impeller has a shaft positioned through the first end of the first housing and into the pump chamber. The impeller includes a distal tip-end at a distal end of the shaft wherein the impeller is configured to be axially displaced within the pump chamber of the viscosity pump parallel to the axis of rotation. An actuator is coupled to a proximal end of the impeller, wherein the actuator is configured to move the impeller parallel to the axis of rotation.
