Abstract Scope |
Binder jet additive manufacturing can achieve complex geometries with metal and ceramic materials, but low green densities and anomalies from powder spreading reduce final part performance. Exploring the multidimensional process parameter space is prohibitively expensive, so identifying and correcting problematic behaviors within a build is necessary for new materials. In this study, Dragonfly image processing software was utilized for the first time to segment additive manufacturing powder bed images. Photos were taken with 316 stainless steel and alumina and segmented using a U-Net convolutional neural network to identify spreading anomalies. The steel and alumina models trained on five print layers each achieved categorical accuracies of 95.4% and 92.3%, respectively. Trends in the number of pixels with each label reflected changes in conditions, including removing an anomaly type through parameter adjustments. Automated build monitoring for anomaly correction allows for improved part quality and the development of closed-loop additive manufacturing. |
