Corroborating in-situ two-color pyrometry with post-build micro-computed tomography has previously been demonstrated to reasonably identify defects in additively manufactured 316L stainless steel. Overcoming resolution variance between imaging modalities and resolving non-uniform distortions in pyrometry data reveal a greater predictive ability for this in-situ technique than previously observed. This talk will also show how effective and reliable identification of anomalous melt pools can be leveraged toward informing real time processes to better mitigate the occurrence of defects in additive manufacturing builds by intercepting the events that result in pore formation before they occur. Additional recommendations for the practical integration of two-color pyrometry in additive manufacturing will also be provided.
