This award funds planning activities at University of Alabama (UA) for a proposed new three-site industry university cooperative research center (IUCRC), the Center to Accelerate Recipe Development for Additive Manufacturing of Metals (CARDAMOM). CARDAMOM is led by the University of Nebraska-Lincoln in partnership with the University of Texas Rio Grande Valley, and the University of Alabama. Metal additive manufacturing (AM), also known as metal 3D printing, is transforming manufacturing within the United States and around the world. This new disruptive technology has already resulted in several success stories, primarily within the aerospace and biomedical sectors. However, further expansion to the greater manufacturing community is impeded by limitations in powder feedstocks, a lack of access to flexible and comprehensive metal AM research and production facilities, and a workforce with limited AM design experience. CARDAMOM proposes to address these research needs by assisting industry members along the entire “powder-to-part” development cycle to address fundamental research questions with a view toward final engineering applications. In addition, the team will address societal impacts of education and workforce development which will have a significant impact on the training of students from diverse backgrounds and educational institutions. Eventually, CARDAMOM aims to be a steady provider of high-quality engineers and technicians to manufacturers and government research laboratories. The mission of CARDAMOM is to transform the manufacturing of high-performance, quality metallic components created with AM via active engagement with Center industry members. With respect to the technological impacts, CARDAMOM will pursue multiple thrusts in order to: develop methods for production of AM feedstocks for new alloys; develop new methods and techniques to understand and interpret in situ measurement data; use advanced characterization to provide 3D microstructural and nanostructural information that connects processing methods to component performance; develop new computational methods to predict and understand microstructural development, leading to better ways to design new materials and processes; develop innovative measurements to quantify laser-metal interactions; use advanced metrology and NDE to enhance AM build quality; develop new data analytical (machine learning) approaches for data interpretation and scientific insight. CARDAMOM will engage potential members across the full supply chain, including equipment manufacturers, aerospace and defense companies, tool and die producers, materials development companies, process optimization designers, and government laboratories. The University of Alabama will specifically emphasize, custom metallic alloy powder production, solid state additive manufacturing process development, and advancement and application of ICME tools for AM materials and process development. The Alabama Atomization Facility has an inert gas atomization capability, which is routinely used to produce AM-appropriate metallic alloy powders. The faculty at UA have a number of active programs involving cold spray, laser assisted cold spray, and additive friction stir deposition for AM. UA has faculty who are developing and implementing ICME methods across length and time scales to enable alloy and process design, specifically benefiting AM approaches.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项资金为阿拉巴马大学（UA）的计划活动提供了拟议的新三站工业大学教练研究中心（IUCRC），该研究中心加速了金属添加剂（Cardamom）的配方开发中心。豆蔻由内布拉斯加州林肯大学（University of Nebraska-Lincoln）与德克萨斯大学里奥格兰德大学（Rio Grande Valley）和阿拉巴马大学合作。金属添加剂制造（AM），也称为金属3D打印，正在美国和世界各地转变。这种新的破坏性技术已经导致了几个成功案例，主要是在航空航天和生物医学领域。但是，粉末原料的局限性，缺乏灵活和全面的金属AM研究和生产设施以及具有有限的AM设计经验的劳动力，这阻碍了更大的制造社区的进一步扩展。小豆蔻提出的建议通过在整个“粉末”开发周期协助行业成员来解决这些研究需求，以解决基本的研究问题，以期待最终的工程应用程序。此外，该团队将解决教育和劳动力发展的社会影响，这将对来自潜水员背景和教育机构的学生的培训产生重大影响。最终，豆蔻的目标是成为制造商和政府研究实验室的高质量工程师和技术人员的稳定提供者。豆蔻的任务是改变由AM与中心行业成员积极参与而创建的高性能，优质金属组件的制造。关于技术的影响，豆蔻将采取多种推力，以便：用于生产新合金的AM原料的开发方法；开发新的方法和技术来理解和解释原位测量数据；使用高级表征提供3D微结构和纳米结构信息，将处理方法连接到组件性能；开发新的计算方法来预测和理解微观结构发展，从而为设计新材料和流程提供更好的方法；开发创新的测量以量化激光金属相互作用；使用高级计量学和NDE来提高AM的构建质量；开发新的数据分析（机器学习）方法，以进行数据解释和科学见解。豆蔻将吸引整个供应链中的潜在成员，包括设备制造商，航空航天和国防公司，工具和模型生产商，材料开发公司，流程优化设计师和政府实验室。阿拉巴马大学将特别强调定制的金属合金粉末生产，固态添加剂制造过程开发以及ICME工具用于AM材料和过程开发的进步和应用。阿拉巴马州的雾化设施具有惰性气体雾化能力，该功能通常用于生产适合AM的金属合金粉末。 UA的教职员工有许多活跃的计划，涉及冷喷雾，激光辅助冷喷雾和AM的添加摩擦僵硬的沉积物。 UA有教师正在开发和实施跨长度和时间尺度的ICME方法，以使合金和过程设计特别受益于AM方法。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响来评估来获得的支持。
