US national 3D printing accelerator美国制造已授予由航空航天制造商领导的团队波音$ 500,000英寸美国空军研究实验室（AFRL）资金。
被选为美国的一部分，波音现在将与RPM创新开发与具有高速应用的零件的3D打印有关的技术。具体而言，该团队将继续磨练他们的获胜设计方法，以高超音速速度使用时，该方法被理解为提高这些组件的可靠性，最多会造成失真风险。
“These efforts will serve to benefit the manufacturing of a wide variety of products which feature complex geometric features,” said America Makes’ Technology Director, Brandon D. Ribic, Ph.D. “It is anticipated important lessons learned from these efforts will help to improve yield of complex structures incorporating AM components.”
美国使'创新驱动器
Since it was founded in Youngstown, Ohio, back in 2012, America Makes has worked tirelessly to accelerate the adoption of 3D printing in a way that advances the USA’s global manufacturing competitiveness. One of the primary ways the institute has sought to achieve this, is via its Project Calls, through which it offers backing to member organizations with fresh approaches to common 3D printing issues.
In the last 12 months alone, America Makes has launched several such initiatives, including itsmost recent Rapid Innovation Call（RIC）认为，它保证另外500,000美元用于推进3D打印的项目，针对六个不同领域，从原位监测和资格鉴定到部分缺陷检测和轻量化。
During June 2021, the institute also announced a$1.6 million Open Project Call旨在鼓励开发创新，具有成本效益和节能的增材制造方法。在AFRL的支持下，该计划不仅看到美国继续寻求减轻缺陷的新方法，而且还针对新的培训和高温物质资格方法。
最近，3D打印加速器更加重视寻找克服高速使用加成式制成部分的问题的方法。介绍了它$ 500,000的“熔岩”项目电话last year, in which it invited non-DED approaches to preventing distortion at high-speed, America Makes has now followed this up with the similarly-named and targeted ‘MAGMA’ initiative.
将$ 500K倒入高速研发
Operating as part of America Makes’ Hypersonics Enabling Additive Manufacturing program, the organization’s Maturation of Additive Geometric Management Approaches or ‘MAGMA’ for High Mach Applications project, has been set up specifically to further the maturation of 3D printing technologies for deployment within high-mach applications.
当美国于2021年10月首次发布其岩浆项目电话会议时，它概述了增材制造业越来越多地帮助美国公司减少定制，复杂零件的交货时间。但是，当时，研究所建议目前各种因素可能导致“产品几何形状的不可接受的差异”，这阻止了3D打印的零件在高速上使用。
To overcome this, America Makes has since been inviting design and 3D printing proposals with the potential to yield a “measurable improvement in product-relevant geometric acceptance criteria.” As examples, the organization indicated that entries could range from statistical analyses to the creation of novel design tools, but chose to encourage innovation rather than mandate an approach.
尽管波音和RPM创新现在已经志愿人员组织eiled as the winning MAGMA call entrants, the sensitive nature of their hypersonics-related research means that little has been made public about their submission. Given that RPM Innovation specializes in using DED 3D printing to manufacture and repair parts, however, it’s highly-likely that itsFreeform process将对团队的方法有用。
Additionally, Ribic has said that the project’s findings could be used to “advance the supply chain’s understanding of AM technologies for a variety of high-mach applications,” but the fact that Boeing has taken point in the initiative, suggests that its application will relate closely to its core business, which revolves around aircraft, aerospace and defense manufacturing.
美国国防的高超声研究
As global tensions continue to rise over Russia’s invasion of Ukraine, the importance of US hypersonic technologies has become clearer than ever before. In fact, the Russian military is said to have been testing its latest ‘Dagger’ missiles in the run up to the conflict, and used 3D printing to升级MIG-31喷气机的引擎capable of carrying them.
Thankfully for the US and its allies, the country is no stranger to hypersonic research itself, and its国防部(DoD) has often turned to 3D printing to achieve progress in this area. In October 2021, for instance, the DoD向超音速研发授予2550万美元预计将部署3D打印，机器学习和NDT方法的项目来推进高空飞行。
大约在同一时间美国海军表面战中心达尔格伦分部（NSWCDD）还宣布打算兼容高超音速研发。Using advanced tech such as 3D printing, in partnership withJohns Hopkins University和迈阿密大学该组织表示，它旨在将达尔格伦（Dahlgren）确立为高超音速武器整合中的水面领导。
