Abstract: A method for printing a three-dimensional part with an electrophotography-based additive manufacturing system having an electrophotography engine, a transfer medium, and a layer transfusion assembly includes providing a part material to the electrophotography-based additive manufacturing system, the part material compositionally comprising a charge control agent, and a thermoplastic material having a heat deflection temperature greater than about 150° C., and has a powder form. The method includes triboelectrically charging the part material to a Q/M ratio having a negative charge or a positive charge, and a magnitude ranging from about 5 micro-Coulombs/gram to about 50 micro-Coulombs/gram and developing layers of the three-dimensional part from the charged part material with the electrophotography engine. The method includes electrostatically attracting the developed layers from the electrophotography engine to the transfer medium and moving the attracted layers to the layer transfusion assembly with the transfer medium, wherein the layer transfusion assembly comprises a nip roller. The method includes transfusing the moved layers to previously-printed layers of the three-dimensional part with by moving the attracted layers about a nip of a nip roller using heat and pressure over time.

Abstract: A method for printing a three-dimensional part and a support structure with an electrophotography-based additive manufacturing system. The method includes developing a support layer of the support structure from a soluble support material with a first electrophotography engine, and transferring the developed support layer from the first electrophotography engine to a transfer medium. The method also includes developing a part layer of the three-dimensional part from an ABS part material with a second electrophotography engine, and transferring the developed part layer from the second electrophotography engine to the transfer medium. The method further includes moving the attracted part and support layers to a layer transfusion assembly with the transfer medium, and transfusing the moved part and support layers together to previously-printed layers with the layer transfusion assembly.
