Abstract
Heat accumulation is likely the main limiting operational characteristic of directed energy deposition additive manufacturing. In this scenario, this work aims to present and explore the potential of a novel thermal management technique, named Near-Immersion Active Cooling (NIAC), to mitigate heat accumulation in Wire + Arc Additive Manufacturing (WAAM), in contrast to conventional cooling approaches. The results revealed that the NIAC technique is a feasible thermal management approach to mitigate preform heat accumulation in WAAM and, consequently, its related drawbacks.
