    Abstract: A method and system, the method including receiving a nominal computer-aided design (CAD) model of a component; producing a physical representation of the component based on the CAD model using an additive manufacturing (AM) process; measuring the produced physical representation of the component to obtain measurement data of the physical representation of the component; determining a deviation between a geometry of the CAD model and the measurement data of the physical representation of the component; calculating a nonlinear scale factor using an iterative simulation process; determining a compensation field based on the determined deviation between the geometry of the CAD model and the measurement data of the physical representation of the component and the calculated nonlinear scale factor; modifying the nominal CAD model by the determined compensation field; and producing a physical representation of the component based on the modified nominal CAD model.

    Abstract: A computer-enabled device for dynamically creating or modifying at least a portion of an additive manufacturing build for making a part is provided. The device is in direct or indirect communication with one or more additive manufacturing machines that use one or more build parameters. The device is configured to analyze a plurality of build information pertaining to the part. The device is also configured to assess whether one or more differences between the pre-existing data and the non-pre-existing data will result in a deviation from, or improvement to, the part, the additive manufacturing build, or both and automatically create or modify, one or more of the build parameters of the part, at least a portion of the additive manufacturing build, or a combination thereof, based on the assessment of the one more differences.
