After a series of trials and prototypes, the world's first 3D-printed and class-approved ship propeller was unveiled at Damen Shipyard Group’s headquartered in Gorinchem. The WAAMpeller was created using innovative Wire Arc Additive Manufacturing (WAAM) techniques developed by RAMLAB to lay down 298 layers of Nickel Aluminum Bronze alloy through a 3D printing process. The WAAMpeller is the result of a close collaboration between RAMLAB, Promarin, Autodesk, Bureau Veritas and Damen. After putting the propeller through rigorous trials on one of Damen’s Stan Tug 1606 series and verifying the entire development, production and testig process, Bureau Veritas provided its stamp of approval. RAMLAB was built so replacement parts for ships could be easily 3D printed onsite, rather than having to wait weeks or even months for delivery of a new part, disrupting shipping schedules.
