Symposium 2026 Annual International Solid Freeform Fabrication Symposium (SFF Symp 2026)
Presentation Title A Framework for Comparison of In-Situ and Finite Element Data in Wire-Arc Directed Energy Deposition
Author(s) Clark Hensley, Jeffrey Logan Betts, Elise Roberson, Charlotte Thompson, David Johnson, Matthew W. Priddy
On-Site Speaker (Planned) Clark Hensley
Abstract Scope In-situ monitoring (ISM) of wire-arc directed energy deposition (arc-DED) provides insight into the process parameters during deposition. This information can be used to study the final state of the printed part. One tool for using this data to determine this state is finite element analysis (FEA). The data formats used by ISM and FEA do not interoperate. This work introduces a pipeline to translate Abaqus FEA data into a format legible to Robot Operating System 2 (ROS 2) ISM systems. This data is aligned with the deposited component. Aligned data is then leveraged to perform real-time comparison between FEA simulations and in-situ arc-DED depositions. This pipeline provides a foundation for real-time decision-making during arc-DED informed by FEA. This work focuses on converting Abaqus data into the PVD (Paraview data) format, integrating this data into ROS 2, aligning data with real-time arc-DED deposition, and comparing thermal gradients of experiments and simulations.
