The Manufacturing and Materials Joining Innovation Center (Ma2JIC) is a multi-university consortium leading materials joining and metal additive manufacturing research by fostering and translating scientific discovery to application. The Center also educates the next generation of scientists and engineers that will develop new advanced manufacturing technologies and process innovations to rebuild the competitiveness of U.S. domestic manufacturing. Given the importance of materials joining for the manufacturing of products that are critical to health, safety, national security, and the continuity of multiple industries, Ma2JIC serves multiple sectors of national interest for the U.S. economy and defense. The center provides a highly collaborative research environment among government partners, industry, and university faculty and students to promote the development and application of fundamental knowledge in materials joining and additive manufacturing. The Center also serves as a platform for the education of a well-trained and diverse scientific and engineering workforce. Ma2JIC’s primary focus on research and development translates into industry members' and consumers' benefit. The coordinated effort across all sites increases public awareness, scientific literacy and a diverse STEM pipeline. Based on the needs of its large and diverse industrial membership, Ma2JIC supports research in the following three thrust areas: (1) Materials & Joints Performance, (2) Additive Manufacturing, Process Development & Control, and (3) Materials, Microstructure & Weldability & Printability. The Materials & Joints Performance thrust focuses on the effect of materials and manufacturing processes on the mechanical, functional and environmental performance of manufactured or printed components, especially with regard to improved reliability, cost reduction and extension of service life of critical infrastructure. The Additive Manufacturing, Process Development & Control thrust area addresses fundamental challenges in joining and additive manufacturing (AM) processes, robotics, and control, as well as integrated computational materials engineering (ICME) frameworks for joining and AM. Finally, the Materials, Microstructure & Weldability & Printability thrust area seeks to develop fundamental understanding and testing capabilities to enable evaluation and development of materials more amenable to advanced joining and manufacturing processes. The Colorado School of Mines (CSM) site has expertise and facilities that directly complement the welding metallurgy and processing specialties of partner sites, especially in the design of filler metals/feedstocks using multi-scale physics-based models, pilot-scale manufacturing of fillers, computing-intensive artificial intelligence and robotics, and state-of-the-art AM equipment with in-process sensing capabilities.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.

制造和材料连接创新中心（Ma 2 JIC）是一个多大学联盟，通过促进和将科学发现转化为应用，领导材料连接和金属增材制造研究。该中心还教育下一代科学家和工程师，他们将开发新的先进制造技术和工艺创新，以重建美国国内制造业的竞争力。鉴于材料连接对于制造对健康，安全，国家安全和多个行业的连续性至关重要的产品的重要性，Ma 2 JIC为美国经济和国防的多个国家利益部门提供服务。该中心为政府合作伙伴，工业和大学教师和学生提供高度协作的研究环境，以促进材料连接和增材制造基础知识的发展和应用。该中心还作为一个受过良好训练的和多样化的科学和工程劳动力的教育平台。Ma 2 JIC的主要重点是研究和开发转化为行业成员和消费者的利益。所有网站的协调努力提高了公众意识，科学素养和多样化的STEM管道。基于其庞大而多样化的工业成员的需求，Ma 2 JIC支持以下三个重点领域的研究：（1）材料接头性能，（2）增材制造，过程开发控制，以及（3）材料，微观结构焊接性印刷性。材料连接性能重点关注材料和制造工艺对制造或打印部件的机械，功能和环境性能的影响，特别是在提高可靠性，降低成本和延长关键基础设施的使用寿命方面。增材制造，过程开发控制重点领域解决了连接和增材制造（AM）过程，机器人和控制以及连接和AM的集成计算材料工程（ICME）框架的基本挑战。最后，材料、微结构可焊性和可印刷性重点领域旨在发展基本的理解和测试能力，以评估和开发更适合先进连接和制造工艺的材料。 科罗拉多矿业学院（CSM）工厂拥有的专业知识和设施可直接补充合作伙伴工厂的焊接冶金和加工专业，特别是在使用多尺度物理模型设计填充金属/原料、中试规模制造填充物、计算密集型人工智能和机器人技术、和最先进的AM设备，该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的评估，被认为是值得支持的。影响审查标准。
