Kawasaki Installs WAAM 3D Printed Propeller on Vessel

Wire Arc Additive Manufacturing (WAAM) is transforming the marine industry by enabling the production of durable, high-performance parts in a fraction of the time compared to traditional methods. Kawasaki Heavy Industries, in partnership with Pelagus 3D, recently showcased the potential of WAAM technology by installing a Nickel Aluminium Bronze propeller blade on the BW Epic Kosan vessel, Epic Salina. This project highlights how additive manufacturing is reshaping the future of marine spare parts, offering on-demand solutions that meet the unique demands of maritime engineering. WAAM’s innovative approach creates complex components layer by layer, reducing lead times, material waste, and operational costs.

Kawasaki’s choice of Nickel Aluminium Bronze for the WAAM-produced propeller blade on the Epic Salina vessel demonstrates the material’s corrosion resistance, strength, and durability in harsh marine environments. The WAAM-manufactured propeller blade boasts a 40% increase in strength compared to traditionally manufactured parts, thanks to its near-full density production process. This quick turnaround in design and installation, completed in just six weeks, is especially beneficial for marine operators who require timely repairs or replacements to minimize downtime.

Pelagus 3D, a joint venture between thyssenkrupp and Wilhelmsen, played a crucial role in manufacturing the WAAM propeller blade for the Epic Salina vessel. The successful collaboration between Kawasaki, Pelagus 3D, and BW Epic Kosan highlights the value of combining expertise in marine engineering, additive manufacturing, and operations. This partnership ensures a smooth and efficient production process, showcasing the potential of WAAM in creating high-quality marine components efficiently and effectively.
