Researchers from the University of Patras have published a new open-access paper contributing to R3GROUP’s scientific output: “Addressing the challenge of process stability control in wire DED-LB/M process”, authored by Panagiotis Stavropoulos, Georgios Pastras, Konstantinos Tzimanis and Nikolas Bourlesas from the Laboratory for Manufacturing Systems and Automation.
Wire Directed Energy Deposition (DED-LB/M) is a promising additive manufacturing process — fast, cost-effective, and capable of producing high-quality, dense parts. However, its broader industrial adoption has been held back by the complexity of the monitoring tools required to ensure process stability.
This paper proposes a practical two-part solution: a fast-running, physics-based simulation tool that calculates the temperature field during the building of single walls, combined with an affordable vision-based monitoring system that captures melt pool dimensions to detect heat accumulation in real time. Together, they enable real-time process stability control without the need for complex and costly equipment.
The paper has been published open access and is available on Zenodo.
