    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: An additive manufacturing system for printing a three-dimensional part using electrophotography, the additive manufacturing system comprising a rotatable photoconductor component, a development station configured to develop layers of a material on a surface of the rotatable photoconductor component, a rotatable transfer medium configured to receive the developed layers from the surface of the rotatable photoconductor component, and a platen configured to receive the developed layers from the rotatable transfer medium in a layer-by-layer manner. The additive manufacturing system also comprises a plurality of service loops configured to move portions of the rotatable transfer medium at different line speeds while maintaining a net rotational rate of full rotations of the rotatable transfer medium at a substantially steady state.
