In recent years, metal additive manufacturing (AM) has gained significant traction in industrial applications across Japan. Wire-laser directed energy deposition (DED-LB/W), an AM process based on build-up welding, is compatible with conventional manufacturing technologies and has been used for applications such as impeller fabrication and mold repair. This method utilizes commercially available solid wire, providing benefits such as low material cost and high deposition efficiency. However, the range of usable materials is constrained by wire-drawing requirements for specified diameters, posing challenges to feedstock customization compared with powder-based AM processes.
KUROSAWA et al. (2025) studied this question.
