3D Systems announced it is collaborating with Huntington Ingalls Industries’ Newport News Shipbuilding division to develop Copper-Nickel (CuNi) and Nickel-Copper (NiCu) alloys for powder bed fusion additive manufacturing. These new materials could allow Newport News Shipbuilding to additively manufacture parts that are traditionally cast – reducing lead times by up to 75% to improve supply chain efficiency.
CuNi and NiCu are well-known alloys that are corrosion-resistant, which makes them ideal for marine applications. While parts produced with these metals possess high strength and toughness over a variety of temperatures, they must currently be produced using traditional casting methods. This requires long lead times – sometimes in excess of 12 months – and multiple suppliers. If these alloys could be formulated for use with metal 3D printing technologies, lead times for some of these parts could be reduced to a fraction of the traditional procurement time.
通过这种材料的开发工作，3D系统正在使用纽波特新闻造船，选择合金组成，设计工艺参数实验，以及限定包括拉伸和其他材料测试的零件。通过这些新材料，纽波特新闻造船将使用其金属AM系统为铸件以及阀门，壳体和支架产生更换零件。随着这些材料的成功使用，3D系统预计将增加它们的材料组合，以解决腐蚀是石油和天然气生产和精炼等主要关注的应用中的广泛应用，以及公用能源生产。
2018年，3D Systems和Newport News造船进入联合开发协议，以资格获得金属添加剂制造技术以建立海军战舰。当时，3D系统提供并安装了一个Prox DMP 320 - 该公司的DMP Flex 350的前身 - 以传统方法从传统方法移动到附加的传统方法的目标。为纽波特新的海洋合金开发新的海洋合金的独特应用需求将使他们继续扩大在其制造工作流程中的作用。
