    The world’s first classification societies certified 3D printing propeller will be born

    At the 2017 Hannover Messe, Autodesk exhibited the first successful test piece, the ship propeller, in cooperation with the Dutch 3D printing lab RAMLAB.

    The Damen Shipyards Group has recently formed an alliance with RAMLAB Labs, the German propeller manufacturer Promarin, the software giant Autodesk and the French classification societies (BV), with the goal of developing the world’s first classification societies certified 3D printing marine propeller WAAMpeller. This initiative will be a revolution in the propeller industry.

    RAMLAB Labs is located in the port of Rotterdam and is committed to metal ship repair and parts production ,using line-to-arc manufacturing (WAAM) technology combined with traditional cutting-edge manufacturing technology. Promarin is a German company, specializing in propeller manufacture. Autodesk will provide software support for the project, the French classification society will follow up the certification process.

    The Damen R & D department’s project Engineer Kees Custers said: “The alliance that contains five companies is unique, although we have a common interest, but also have their own goals. This will create a very fruitful and cooperative atmosphere in this exciting project. ”

    3D printing propeller will be used for Promarin design Damen Stan Tug 1606. After printing the propeller diameter of 1300mm, weighing about 180kg, which will be the first classification societies certified metal 3D printing marine accessories.

    It is understood that the propeller is RAMLAB using the addition and subtraction method of manufacturing, the whole process of the first use of Autodesk software to complete 3D modeling; and then use RAMLAB arc welding 6-axis robot 3D printing: the final by turning and grinding and other traditional reduction The process is finished and finished.

    Once the propeller is printed, Damen will be fully tested. “We will conduct a comprehensive plan, including drag and crash test scenarios.Our goal is to prove that the marine 3D printing research phase has ended and it can now be effectively applied to the operation.”

    After the production and certification process, the summer of 2017 began, the propeller will perform a comprehensive test. These tests include tether tension and crash testing. The column tension test is a traditional method of assessing the quality of the ship, and this process will help prove that 3D printing components can be effectively applied to practice.

    The project not only marks a significant advance in 3D printing technology, but also may have significant results in optimizing ship design in the future. 3D printing technology will bring new ideas and effective methods to improve the structural performance and fuel consumption of ships.
