Abstract: An additive manufacturing method produces a 3D part utilizes electrophotography-based additive manufacturing and molding processes. A layered structure having a cavity is printed on a build platform using at least one electrophotographic (EP) engine to develop imaged layers of powder material, and a transfusion assembly to stack and fuse the imaged layers on the build platform. Molding material is deposited into the cavity as the layered structure is printed, using a deposition unit. The molding material solidifies to form at least a portion of the 3D part, which may also include portions formed from imaged powder material.

Abstract: An imaging system may use pulsed dc voltages to synchronously image on both sides of a receiver material, such as during a single pass of the receiver material through the imaging system. The imaging system may use electrophotographic processes to image on the receiver material. Alternatively, the imaging system may use directed charged particle or aerosol toner development processes to image on the receiver material.

Abstract: An imaging system may use electrophotographic processes to synchronously image on both sides of a receiver material, such as in a single pass of the receiver material through the imaging system. The system may include intermediate transfer members, which may be split rollers or non-split rollers. The intermediate transfer members may hold one image, or they may be 2-up or greater rollers that hold multiple images.

Abstract: An imaging system may include first and second imaging assemblies for synchronously imaging on both sides of a receiver material using directed charged particle or aerosol toner printing methods. The imaging assemblies may in turn each include an imaging member and an intermediate transfer member, and the intermediate transfer member may be a split intermediate transfer member. The imaging system may also use flexible aperture print arrays.
