| Abstract Scope |
Additive manufacturing is revolutionizing product design and manufacturing of metal components across many sectors, and yet printing large-scale parts with the desired material properties remains a challenge. The thermomechanical state evolves during the printing process in ways that can be difficult to predict a priori, and stochastic effects can cause variability in parts printed under nominally identical conditions. In this presentation we discuss a new approach for adaptive control of directed energy deposition (DED) prints. Under the framework of model predictive control, we estimate the thermal state of the part being printed by assimilating in-situ infrared camera data into a faster-than-real-time finite element simulation and then use forward-looking simulations to determine which printing parameters to use for future layers. After showing an example of this control scheme in practice, we discuss progress toward integrating AI agents into this workflow for improved flexibility, adaptability, and ease of use. |
