Claim One:
1. A method for printing a three-dimensional part with an additive manufacturing system, the method comprising: providing a bitslice stack having a plurality of bitslices; printing a plurality of successive layers of the three-dimensional part with the additive manufacturing system based on the bitslice stack; measuring surface heights of a first printed layer to obtain a composite image comprising a plurality of pixels; obtaining predicted stack heights for a bitslice of the plurality of bitslices corresponding to the first printed layer; utilizing the controller to determine differences between the measured surface heights and the predicted stack heights for each of the plurality of pixels; utilizing the controller to identify one or more topographical error regions based on the determined differences including comparing the determined differences to a threshold value, wherein the one or more topographical error regions comprise one or more underfilled regions, one or more overfilled regions, or combinations thereof; and utilizing the controller to modify the bitslice stack to compensate for the one or more topographical error regions.
