朴茨茅斯海军船厂为现役潜艇安装3D打印部件，美国防务领域迎关键里程碑

The U.S. Navy has reached a significant milestone in its adoption of additive manufacturing (AM), successfully installing a metal 3D printed component on an in-service submarine. This landmark event, which took place at Maine’s Portsmouth Naval Shipyard (PNSY) on March 18, signals a major leap forward for 3D printing within the defense sector and highlights the technology’s readiness for mission-critical applications.

美国海军在采用增材制造（AM）方面取得了一项重大里程碑，成功在一艘在役潜艇上安装了金属3D打印部件。这一标志性事件于3月18日发生在缅因州的朴茨茅斯海军造船厂（PNSY），标志着3D打印技术在国防领域向前迈出了一大步，并凸显了该技术已准备好用于关键任务应用。

Maintenance personnel installed a 3D printed copper-nickel flange on the Virginia-class USS Washington. Flanges are essential hardware used to securely connect valves, pumps, and other components in high-pressure systems. The successful deployment of this part, after rigorous inspection and testing, demonstrates the Navy’s growing confidence in the technical maturity of its metal AM program. This move follows a similar installation on the USS Vermont last year and sets a precedent that will likely accelerate the use of 3D printing across the fleet.

维护人员在弗吉尼亚级潜艇华盛顿号上安装了一个3D打印的铜镍合金法兰。法兰是用于在高压系统中安全连接阀门、泵和其他部件的重要硬件。该部件经过严格检查和测试后成功部署，表明海军对其金属增材制造计划的技术成熟度日益增强的信心。此举紧随去年在佛蒙特号潜艇上的类似安装，并开创了一个先例，可能会加速3D打印在整个舰队中的使用。

This achievement is more than a one-off success; it represents a strategic shift in military logistics and manufacturing. For the 3D printing community, it validates several key points:

这一成就不仅仅是一次性的成功；它代表了军事后勤和制造的战略性转变。对于3D打印界而言，它验证了几个关键点：

Navy leadership was quick to highlight the strategic importance of this advancement. PNSY Commander, Captain Jesse Nice, called it a “momentous achievement” born from “teaming and innovation.” Captain Jason Deichler, Commodore of Submarine Squadron TWO, went further, stating that this work is a “war fighting enabler and a key component to enhanced undersea readiness.” Their comments underscore that 3D printing is now viewed as a core capability, not just an experimental tool.

海军领导层迅速强调了这一进展的战略重要性。朴茨茅斯海军造船厂指挥官杰西·奈斯上校称其为源于”团队合作与创新”的”重大成就”。第二潜艇中队指挥官杰森·戴希勒上校更进一步表示，这项工作是一个”增强作战能力的关键因素，也是提升水下战备状态的关键组成部分”。他们的评论强调，3D打印现在被视为一种核心能力，而不仅仅是一种实验性工具。

For enthusiasts and professionals, this news is a powerful reminder of the technology’s potential. While the Navy’s program is highly specialized, the underlying principles—designing for function, qualifying materials, and enabling local production—are directly applicable to any advanced 3D printing project. Whether you’re engineering a prototype or seeking durable, complex premium STL files for functional parts, the bar for what’s possible continues to rise.

对于爱好者和专业人士来说，这则新闻有力地提醒了该技术的潜力。虽然海军的计划高度专业化，但其基本原则——为功能而设计、材料认证以及实现本地化生产——直接适用于任何先进的3D打印项目。无论您是在设计原型，还是为功能性部件寻找耐用、复杂的优质STL文件，可能性的标准都在不断提高。
