Abstract: According to some embodiments, system and methods are provided comprising generating a nominal computer-aided design (CAD) image of a component; producing a physical representation of the component from the nominal CAD image using an additive manufacturing (AM) process; measuring the physical component to obtain measurement data; determining a deviation between geometry associated with the nominal CAD image and the obtained measurement data; determining a compensation field for the deviation, if the deviation is outside of a tolerance threshold; modifying the nominal CAD image by the compensation field; and producing a physical representation of the component from the modified nominal CAD image. Numerous other aspects are provided.
