Dutch engineering company Damen Shipyards Group has partnered with Rotterdam’s Additive Manufacturing Lab (RAMLAB) to 3D print the first certified ship propeller.
Ramlab位于鹿特丹港口，已经开发用于创建用于维修和生产的金属船件。实验室使用电弧添加剂制造（WAAM）工艺与常规减法制造技术结合使用。虽然达门造船厂集团是一家全球企业集团，在国防，造船和工程方面具有专业知识。该公司在2015年的收入为21亿欧元。
Ramlab最近与Autodesk合作3D print a metal ship propellerand will now scale up the process to a full-scale propeller with this new consortium.
Damen和Ramlab与Promarin，Autodesk和Bureau Veritas一起加入了该项目，该项目已创造了Waampeller。
“世界一流的3D印刷船的螺旋桨”
The 3D printed propeller will be based on Promarin’s design that is used for the Damen Stan Tug 1606. Promarin is a German company that specializes in propeller manufacturing.
Autodesk将为该项目的设计提供软件，Ramlab将实施其WAAM制造技术，局Veritas将促进认证过程。最终的3D打印螺旋桨的直径为1,300毫米，重180kg。
达门说“这一”will be the first time that a metal 3D printed maritime component will be approved by Class。”
全面试验
Following the production and certification process which will begin in the summer of 2017, Damen will perform full-scale trials on the propeller. These tests will include bollard pull and crash tests. The bollard pull test is a conventional method of assessing a ship’s power. Damen hopes that this process will help “到证明海事领域3D打印的研究阶段已经结束，现在可以有效地应用于操作。”
Damen’s Principle Research Engineer Don Hoogendoorn, explains the 3D printing project is part of the company’s aims to create more efficient, environmentally friendly vehicles. Hoogendoom states,
Waampeller项目为这一目标做出了贡献，因为它不仅标志着3D打印中的重要进展，而且还可以在优化未来的船只设计方面产生重要的结果。3D打印技术带来了一个很好的机会，可以在性能和燃料消耗方面改善船舶结构。
