荷兰工程公司Damen Shipyards Group已与鹿特丹的添加剂制造实验室（RAMLAB）合作，以3D打印第一个认证的船只螺旋桨。雷电竞充值
The RAMLAB is located in the Port of Rotterdam and has beendeveloped to create metal ship parts for repairs and production. The laboratory uses a wire arc additive manufacturing (WAAM) process in combination with conventional subtractive manufacturing techniques. While Damen Shipyards Group is a global conglomerate with expertise in defence, shipbuilding, and engineering. The company made a revenue of €2.1 billion in 2015.
RAMLAB recently partnered with Autodesk to3D打印金属船螺旋桨现在，将使用这个新的财团将过程扩展到全面的螺旋桨。
达门和RAMLAB are joined by Promarin, Autodesk and Bureau Veritas in this project which has been coined the WAAMpeller.
“World’s first class approved 3D printed ship’s propeller”
3D打印的螺旋桨将基于Promarin的设计，该设计用于Damen Stan Tug1606。Promarin是一家专门从事螺旋桨制造的德国公司。
Autodesk will provide software for the design of the project, RAMLAB will implement its WAAM fabrication technique and Bureau Veritas will facilitate the certification process. The finished 3D printed propeller will be 1,300 mm in diameter and weigh 180kg.
达门states this “将是第一次将班级批准金属3D印刷的海上组件。”
Full-scale trials
在将于2017年夏季开始的生产和认证过程之后，Damen将对螺旋桨进行全面试验。这些测试将包括Bollard的拉和碰撞测试。Bollard Pull测试是评估船舶功率的常规方法。达门希望这个过程将有助于“至demonstrate that the research phase for 3D printing in the maritime sector is over, and that it can now be effectively applied in operations。”
Damen的主要研究工程师Don Hoogendoorn解释说，3D打印项目是该公司创建更高效，环保的车辆的一部分。Hoogendoom说，
The WAAMpeller project contributes to this goal because it not only marks an important advance in 3D printing, but it also has the potential to yield significant results in optimising future vessel designs. 3D printing technology brings with it an excellent opportunity to improve ship structures in terms of both performance and fuel consumption.
