| Abstract Scope |
While additive manufacturing offers the promise of groundbreaking design freedom, qualification remains a significant bottleneck. In-situ monitoring—using tools like melt-pool imaging, pyrometry, and profilometry—for real-time insights into defects and process stability is increasingly recognized as an integral part of the AM process. Many early systems implementations offered static reporting capabilities, and there is growing industry-wide recognition of the need to advance toward closed-loop, adaptive systems to reduce defects, accelerate qualification, and enable microstructural control during fabrication. Toward this, we are introducing here an in-situ closed-loop processing monitoring and control system initially released and under continual advancement since 2016. In this discussion we will explore how closed-loop control and data logging is used to accelerate parameter development and optimization for alloy development and Functionally Graded Materials (FGM) using DED technology. |
