  • Patent number: 10180649
    Abstract: A system and method are provided for implementing a unique electrophotographic layered manufacturing scheme for creating higher fidelity electrophotographic composite laminate layers using tri-level electrophotography or electrostatic imaging scheme as a process for rendering individual laminate layers to be built up to form and/or manufacture three-dimensional objects, parts and components as 3D objects. A multi-stage 3D object forming scheme is described involving steps of multi-component laminate forming in a particularized electrophotographic layer forming process. This process renders a part component and a support component precisely next to one another with a single exposure by an exposing device to form a latent image of variable discharge voltages. Multiple toner product sources are used to dispose part component toner and support component toner in the forming of the multi-component laminate layer.
