Abstract Scope |
Real-time process control based on online decision-making has long been considered an effective strategy to mitigate defects in the metal additive manufacturing process. This is because the uncertainties inherent in the highly dynamic and unstable process make it impossible to plan for all the unexpected situations that might arise during printing. However, by adaptively controlling the build in response to its current state and trajectory, it becomes possible to circumvent conditions that lead to defect formation. Although recent advancements in online monitoring have yielded remarkable progress in enhancing real-time diagnostic capabilities, the deployment of prognostic real-time process control has lagged due to several hurdles. One of these is a need for a robust process model that can be consulted in real time for guidance. This talk will discuss, with recent examples, the role of physics-based and data-driven models in providing the predictive capabilities required for intelligent online closed-loop control. |
