Additive manufacturing, or AM, provides a great level of flexibility in the design-driven fabrication of metal builds. However, the more complex the design, the more difficult it becomes to control the quality. Advanced imaging is increasingly invested in AM processes to cope with the complexity and enhance information visibility, thereby leading to data-rich environments. Realizing full potentials of image data for quality assurance and quality control (QA/QC) depends to a great extent on the development of novel analytical methods that extract useful information (i.e., process-structure-property relationship identification and causal discovery).
In this talk, Chen will present two projects that leverage image data and AI to analyze and understand the design-quality interactions along with causal relationships in AM. In the first topic, Chen will present a novel generalized recurrence network approach to represent, model, and analyze the AM spatial image data. This proposed design-quality analysis shows great potential to optimize engineering design and enhance the quality of AM builds. In the second topic, Chen will present an ontology-driven Bayesian network model to infer causal relationships between AM design and process parameters and QA/QC requirements (e.g., structure and mechanical properties). The proposed causal discovery model enables engineering interpretations and can further advance AM process monitoring and control. In the end, Chen will talk about her future research plan.
