Abstract: A method of operating a selective deposition based additive manufacturing system capable of producing a three-dimensional (3D) part includes developing a first layer using at least one electrostatography engine, transfusing the first layer on a part build surface using a transfusion assembly to build the 3D part in a layer-by-layer manner on a part build platform such that a portion of the first layer further builds a fiducial structure in a layer-by-layer manner on the part build platform, measuring a height of the fiducial structure, computing an error between the measured height of the fiducial structure and a target height, adjusting a parameter of the at least one electrostatography engine as a function of the error, developing a second layer using the at least one electrostatography engine in accordance with the adjusted parameter, and transfusing the second layer using the transfusion assembly to further build the 3D part.

Abstract: An additive manufacturing system and process for printing a three-dimensional part, which includes one or more electrophotography engines configured to develop layers of the three-dimensional part, a printing assembly configured to print the three-dimensional part from the developed layers, and a planarizer configured to conduct solvent-assisted planarizations on intermediate build surfaces of the three-dimensional part after one or more of the developed layers are printed.
