ADDITIVE MANUFACTURING WITH VIRTUAL PLANARIZATION CONTROL

摘要

A method and system (10) for printing a three-dimensional part (80), which includes printing a plurality of successive layers of the three-dimensional part (80) with the additive manufacturing system (10) based on bitslices (116) in a bitslice stack (118), 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 (116), identifying one or more topographical error regions based on the determined differences, and modifying the bitslice stack (118) to compensate for the one or more topographical error regions.
