| Abstract Scope |
Development of wire feedstock and process control will help accelerate the adoption of the wire direct energy deposition (wire-DED) process for large-scale additive manufacturing (AM). Print material performance can be improved using welding wires designed with the Reactive Additive Manufacturing (RAM) technology, which is a 3D printing technique that utilizes a thermodynamic reaction during printing to create nucleation sites, resulting in fine grain metal structures. This paper discusses the results of development tests carried out using the wire-DED printing process with RAM alloy welding wires, providing insight into the challenges and opportunities in terms of material performance and process control. Small-scale test pieces were used for material testing, and representative “pathfinder” demonstration test pieces, produced using weld simulations, were used to assess the potential of wire-DED for applications with complex geometries that could enable markets in many industry sectors, such as space & aerospace, energy, and defense. |
