A system (100) and method for analyzing a build file (104) in an additive manufacturing process for predicting and analyzing defects in an additive part. The method further includes the steps of reading an additive build file (104) containing a set of scan paths, analyzing the scan paths for potential defects, creating transfer functions that correspond to any melt pools along the scan paths and then predicting pores, excessive melting and surface finish. A probability of melting along the scan path can also be computed along with a prediction for melt pool shape, which both can be used to analyze the build file (104) and create a stronger 3D printed part.
