| Scope |
This symposium focuses on recent advances in large-scale additive manufacturing (LSAM) of high-performance alloys and multi-material systems, with emphasis on repair, repairability, remanufacturing, and qualification of critical components. Topics of interest include processing-microstructure-property relationships, interfacial phenomena in dissimilar material systems, solidification behavior, defect evolution, residual stress management, and microstructural engineering in large-scale AM processes such as directed energy deposition (DED), wire arc additive manufacturing (WAAM), and hybrid manufacturing approaches. Contributions addressing in-situ sensing, digital manufacturing, machine learning, qualification methodologies, and industrial implementation are also encouraged.
Applications of interest include aerospace, maritime, defense, energy, and nuclear industry. The symposium aims to bring together researchers from academia, national laboratories, and industry to discuss emerging scientific and technological developments enabling the deployment of LSAM in demanding applications.
