    Abstract: A cooling assembly, and method, for an article being printed using a selective toner electrophotographic printing system is disclosed. The assembly includes a surface for delivering and returning cooling gas, the surface containing first plurality of elongate openings in communication with a cooling gas supply; and a second plurality elongate openings in communication with a cooling gas return; wherein the first plurality of elongate openings and second plurality of elongate openings are substantially parallel to one another and alternate with one another.

    Abstract: In a method of printing a 3D part in accordance with a selective deposition additive manufacturing process a first image portion of a flowable material is developed using a first electrophotographic engine. A second image portion of a resilient material is developed using a second electrophotographic engine. The first image portion is registered with respect to the second image portion to form a combined image layer comprising the first and second image portions on a transfer medium. The combined image layer is transfused from the transfer medium to a part build surface of a 3D part. The viscosity (Vr) of the resilient material is greater than or equal to three times the viscosity (Vf) of the flowable material, and/or the storage modulus (Er) of the resilient material is greater than or equal to three times the storage modulus (Ef) of the flowable material.

    Abstract: A method of selective deposition-based additive manufacturing includes conveying a layer (28) of material to previously built layers (22) of material. A determination is made as to whether at least one of the conveyed layers (28) of material and a top previously built layer (22) of material contains an unsupported portion (302). When at least one of the conveyed layer (28) of material and the top previously built layer (22) of material contains an unsupported portion, a first set of steps (306, 408, 506) are used to transfer the conveyed layer (28) of material to the top previously built layer (22) of material. When neither of the conveyed layer (28) of material and the top previously built layer (22) of material contains an unsupported portion, a second set of steps (304, 406, 504) are used to transfer the conveyed layer (28) of material to the top previously built layer (22) of material.

    Abstract: A method of operating a selective deposition-based additive manufacturing system capable of building a three-dimensional (3D) part includes developing a first layer using at least one electrostatographic engine, conveying the first layer from the at least one EP engine to a transfusion assembly, determining an anticipated transfusion overlay error for the first layer, determining whether the anticipated transfusion overlay error exceeds an overlay error specification, discarding the first layer after determining that the anticipated transfusion overlay error exceeds the overlay error specification, developing a successive layer using the at least one electrostatographic engine, conveying the successive layer from the at least one electrostatographic engine to the transfusion assembly, and transfusing the successive layer on a part build surface using the transfusion assembly to build the 3D part in a layer-by-layer manner on a part build platform.

    Abstract: A method of producing a 3D part using a selective deposition based additive manufacturing system can include developing a first layer using at least one electrostatography engine, determining a first cross-track offset distance between an average cross-track symmetry line of the first layer and a centerline of a transfer medium, transferring the first layer to the transfer medium such that the average cross-track symmetry line of the first layer is aligned with the centerline of the transfer medium, moving a build platform relative to the transfer medium in the cross-track direction to align the first layer on a part build surface, and transfusing the first layer on the build platform using a transfusion assembly to build the part in a layer-by-layer manner. The first layer comprises at least one of a part material and a support material. The first cross-track offset distance is measured in a cross-track direction perpendicular to an in-track direction of movement of the transfer medium.
