Abstract:
A method for printing a three-dimensional part with an additive manufacturing system includes providing a bitslice stack having a plurality of bitslices and printing a plurality of successive layers of the three-dimensional part with the additive manufacturing system based on the bitslices in the bitslice stack. The method includes measuring density of the three-dimensional part under construction near an intermediate build surface after one or more of the successive layers are printed. The method includes determining differences across the intermediate build surface of the measured density to a targeted density to identify one or more density error regions across the intermediate build surface, wherein the density error regions comprise low density regions, and modifying the bitslice stack to compensate for the one or more density error regions.
