美国制造与NCDMM启动1450万美元国防增材制造认证计划

A significant barrier in high-stakes 3D printing is about to be challenged. America Makes, the national additive manufacturing (AM) institute, and the National Center for Defense Manufacturing and Machining (NCDMM) have announced two major project calls backed by $14.5 million in Department of Defense funding. The target? Tackling the complex, time-consuming process of qualifying 3D printed parts for military use, a critical step to move prototypes from the lab to the field.

高风险3D打印领域的一个重大障碍即将受到挑战。美国制造——国家增材制造（AM）研究院，与国防制造与加工国家中心（NCDMM）宣布了两项由美国国防部1450万美元资金支持的重大项目征集。目标是什么？解决军用3D打印部件认证这一复杂且耗时的过程，这是将原型从实验室推向战场的关键一步。

The larger initiative, Delta Qual 2.0, is funded with $9 million and aims to overhaul qualification inefficiencies across the defense supply chain. It focuses on three key technical areas to build a more agile system:

规模更大的Delta Qual 2.0计划，获得了900万美元资助，旨在彻底改革整个国防供应链中的认证低效问题。它聚焦于三个关键技术领域，以构建一个更灵活的系统：

“Modernizing qualification for advanced manufacturing is essential to maintaining our defense readiness,” said John Martin, Additive Manufacturing Research Director at America Makes. “This project lays the groundwork for a more agile, trusted, and scalable manufacturing ecosystem.” This drive for reliability and trust in industrial 3D printing processes mirrors the precision and quality that creators seek when sourcing premium STL files for their own critical projects.

“现代化先进制造的认证流程对于保持我们的国防战备状态至关重要，”美国制造的增材制造研究总监约翰·马丁表示。“这个项目为一个更灵活、更可信、更具可扩展性的制造生态系统奠定了基础。”这种对工业3D打印工艺可靠性和可信度的追求，与创作者为其自身关键项目寻找优质STL文件时所追求的精度和质量如出一辙。

The second project, named GOTHAAM (Generation Of Technical-data for High-strength Aluminum Alloy Material), is backed by $5.5 million. Its mission is to qualify a high-strength, corrosion-resistant aluminum alloy (equivalent to 7075-T73) for use across different sizes of LPBF machines. While this alloy is prized in aerospace and defense, its adoption in AM has been stalled by a lack of comprehensive material property data.

第二个项目名为GOTHAAM（高强度铝合金材料技术数据生成），获得了550万美元支持。其使命是认证一种高强度、耐腐蚀的铝合金（相当于7075-T73），使其能够用于不同尺寸的LPBF机器。尽管这种合金在航空航天和国防领域备受推崇，但由于缺乏全面的材料性能数据，其在增材制造中的应用一直停滞不前。

The project will unfold in two phases:

该项目将分两个阶段展开：

“Qualifying advanced AM materials like this alloy directly strengthens the Defense Industrial Base,” Martin added. “By delivering validated data… we’re giving U.S. manufacturers what they need to produce reliable components for critical defense systems.”

“认证像这种合金这样的先进增材制造材料，直接加强了国防工业基础，”马丁补充道。“通过提供经过验证的数据……我们正在给予美国制造商生产关键国防系统可靠部件所需的东西。”

These initiatives address what is often called the “qualification bottleneck.” With the DoD planning to invest billions in additive manufacturing, the ability to confidently certify parts is the bridge between capability and deployment. The methodologies, standards, and data generated from these defense-focused projects have a history of trickling down, ultimately influencing best practices and material databases used in commercial aerospace, automotive, and other demanding industries. For enthusiasts and professionals alike, understanding these advancements highlights the evolving sophistication behind the technology used to create 3D printing models for all applications.

Both project calls launched in late March, with proposal submissions due by June 2, 2025. This concerted push signals a pivotal moment: the industry is moving beyond simply proving 3D printing works, to systematically proving it works reliably, every time, for the most critical applications.
