Abstract: An additive manufacturing system for printing a three-dimensional part, which includes one or more electrophotography engines configured to develop layers of the three-dimensional part, a rotatable transfer belt configured to receive the developed layers from the electrophotography engine(s), a detector configured to measure powder densities of the developed layers on the rotatable transfer belt, and to transmit signals relating to the measured powder densities to a controller assembly, and a printing assembly configured to receive the developed layer from the rotatable transfer belt and to print the three-dimensional part from the developed layers.

Abstract: A method and system for printing a three-dimensional part, which includes printing a plurality of successive layers of the three-dimensional part with the additive manufacturing system based on bitslices in a bitslice stack, measuring surface heights of the successive layers after each of the successive layers are printed, determining differences between the measured surface heights and predicted stack heights of the bitslices, identifying one or more topographical error regions based on the determined differences, and modifying the bitslice stack to compensate for the one or more topographical error regions.
