Abstract Scope |
Wire-based directed energy deposition (DED) enables rapid fabrication of large-scale components, but extended cooling durations—particularly for alloys like Inconel 625—remain a major bottleneck, often exceeding 30 minutes per layer. This work introduces an integrated cooling device designed to significantly reduce these idle periods by safely accelerating cooling below 300 °C, a threshold known not to compromise microstructural integrity. The system features a compact heat exchanger and a flexible contact interface that adapts to irregular surfaces. Enhanced thermal contact is achieved through a membrane structure and thermal paste. Experimental results demonstrate a 40% decrease in sub-300 °C cooling time, leading to an overall build time reduction of up to 30%. For long-duration builds, this translates to saving approximately one week in a three-week production schedule. |
