Claim:
1. An additive manufacturing system for printing a three-dimensional part, the additive manufacturing system comprising: one or more electrophotography engines configured to develop one or more layers of the three-dimensional part; a rotatable transfer belt configured to receive the one or more developed layers from the one or more electrophotography engines; a detector configured to measure at least one parameter related to a powder density corresponding to one developed layer of the one or more developed layers on the rotatable transfer belt, and to transmit signals relating to the measured at least one parameter for at least one of the developed layers; 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; and a controller assembly configured to receive the transmitted signals from the detector, compare the received signals to a set point, and adjust one or more process parameters while developing one or more subsequent layers based on a difference between the received signals and the set point.
