US Navy metal 3D printing for battleships

这U.S. Office of Naval Research(ONR) is bringing the Navy closer to 3D printing metal parts for vital air, ground and sea platforms.

ONR已授予并发技术公司(CTC) a two year $2.6 million contract, with a $3.8 million option, to ensure the manufacturability of metal 3D printed parts.

合同是金属添加剂质量的一部分Manufacturing (Quality MADE) program, an ONR initiative to enable cost-effective, on-demand production of 3D printed metal parts, for use in maintenance, repair and overhaul (MRO).

全球海军MRO市场已预测信誉研究to grow at a rate of 8.8 percent annually between 2017-2025.

海军MRO需要3D打印满足

CTC将与项目团队成员合作使用激光粉末床融合金属3D打印制造组件：SLM解决方案N.A.，，，，MSC软件，，，，MRL材料资源有限责任公司，这University of Pittsburgh，，，，and美国制造。

去年，海军行动副总裁威廉·莫兰（William Moran）表示，由于海军部队的需求量很高，海军正面临“下降准备螺旋”。CTC及其项目团队成员将寻求通过快速开发MRO的金属3D印刷组件来解决此问题。

根据ONR的说法，“衰老的海军平台受到传统供应源减少的挑战。为了应对这一需求，海军战中心，维护仓库和FRC计划使用添加剂制造生产少量的生产外或长时间的金属组件。”

CTC CEO, Edward J. Sheehan Jr., concurred saying “personnel and aging equipment are stretched thin amid years of war, statutory budget caps and temporary workarounds, end-strength cuts, and Congress passing continuing resolutions.

In response to this need, Concurrent Technologies Corporation and its integrated project team members are providing new technology that can address the short and long-term challenge of replacing aging or broken parts literally on site.”

海军对3D打印的承诺

合同进一步推进了美国海军对3D印刷的承诺。海军最近与增材制造数据收集和软件开发公司合作森沃尔。伙伴关系将发展加急创建3D打印零件的机器学习程序。

Stratasys和SIA Engineering Company正在打开service center in Singaporeto “advance the use of additive manufacturing” to solve the “unique challenges of the MRO segment.”

Other naval operators are also benefiting from 3D printing. Spanish ship builder纳瓦蒂亚istrialing 3D printed parts aboard its Monte Udala Suezmax oil tanker。It has replaced 25 kilos of steel with 3.5 kilos of 3D printed ABS reinforced with carbon fiber.
