Symposium 2024 Annual International Solid Freeform Fabrication Symposium (SFF Symp 2024)
Presentation Title Demonstration of Numerical Optimal Control for Multiple Fusion-based Additive Manufacturing Processes
Author(s) Mikhail Khrenov, William Frieden Templeton, Sneha Prabha Narra
On-Site Speaker (Planned) Mikhail Khrenov
Abstract Scope Spatially varying heat input in AM processes provides both opportunities and challenges for process planning. While heuristic methods and grid-based process mapping have been useful guides for parameter choice, they struggle with highly transient scenarios, varying part geometries, and are not suited to directly optimizing outcomes. In this talk, we examine an alternative approach based on formulating AM processes in state-space and solving for process plans using numerical trajectory optimization. We demonstrate this approach in two different AM processes: electron beam powder bed fusion (EB-PBF) and wire arc additive manufacturing (WAAM). In the EB-PBF case, we seek to minimize thermal variance over a layer. In the WAAM case, we seek to drive the part’s microhardness to follow a desired distribution. We solve both cases using a common set of tools for additive manufacturing optimal control (ADDOPT) that we have developed, and demonstrate the solutions with experimental validation.
