Additive manufacturing (AM), also known as 3D Printing, is the process of making customized parts layer-by-layer, directly from a digital file without the need for part-specific tooling. Relative to conventional manufacturing processes, AM can shorten lead times, reduce waste, avoid supply chain disruptions, and enable unprecedented levels of functionality, design freedom, and customization with significant benefit to industries ranging from aerospace systems to medical devices. This Leading Engineering for America's Prosperity, Health, and Infrastructure (LEAP-HI) Grant Opportunity for Academic Liaison with Industry (GOALI) project supports fundamental research to establish new AM capabilities for smart devices that can be rapidly customized for individual patients and enable engineered changes in shape as the patients’ needs change. The highly integrated nature of this project requires addressing challenges in materials science, design engineering, and AM simultaneously to enable robust manufacturing of advanced smart devices–projected to be a $98.2 billion market by 2025–thus improving US competitiveness in crosscutting industries from medical devices to advanced electronics. Moreover, the project provides an opportunity for a gender studies scholar to study the process of collaboration among the all-female team of PIs and develop a better understanding of how technological and scientific advances are achieved and how to support technical leaders of any gender as they pursue similar goals. Despite recent advances in AM technologies and the growth of research into smart devices and active materials, including printable ones, few researchers have demonstrated AM of smart multimaterial structures and devices. This award provides a transformative opportunity to address this gap in knowledge by careful integration of processing, modeling, design, and characterization, and by investigating the complex interactions between multiple foci. Fundamental investigations include: (1) development of new polymer-based active materials with significantly enhanced performance via gradation of fillers, (2) development of a novel AM process that integrates multiple materials and functionally grades them on demand, (3) development of an efficient, robust design method that accounts for process variability, and (4) an ethnographic analysis of the female leadership team with the potential to positively impact the field of mechanical engineering more broadly. The results are expected to enable the creation of customizable smart devices that can be commercialized by industry partners in medical and other fields.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.

添加剂制造（AM），也称为3D打印，是直接从数字文件中进行定制零件的过程，而无需特定部分的工具。相对于常规制造过程，AM可以缩短交货时间，减少浪费，避免供应链中断，并实现前所未有的功能，设计自由和定制水平，对从航空航天系统到医疗设备的行业具有重大好处。这项针对美国繁荣，健康和基础设施（LEAP-HI）的领先工程授予了与工业联络（Goarii）项目的学术联络机会，该项目支持基础研究，为智能设备建立新的AM功能，可以为个别患者迅速定制，并随着患者需求的变化而启用工程化的形状变化。该项目的高度综合性质需要应对材料科学，设计工程的挑战，并且仅仅是为了使高级智能设备的强大制造能够到2025年，即在2025年到达982亿美元的市场 - 因此，美国从医疗设备到高级电子产品的交叉挑战竞争力。此外，该项目为性别研究科学提供了一个机会，可以研究全女性PIS团队之间的协作过程，并更好地了解技术和科学进步如何被证明以及如何支持任何性别的技术领导者，因为他们实践了类似的目标。尽管AM技术最近的进步以及包括可打印材料在内的智能设备和活跃材料的研究的增长，但很少有研究人员证明AM具有智能的多材料结构和设备。该奖项提供了一个变革性的机会，可以通过仔细整合处理，建模，设计和表征来解决知识的差距，并通过调查多个焦点之间的复杂相互作用。基本研究包括：（1）开发新的聚合物的活性材料，并通过填充剂的等级开发具有显着增强的性能，（2）开发一种新颖的AM过程，该过程将多种材料整合并按需整合到功能上，（3）开发有效，可靠的设计方法，该方法是一种有效的，可靠的过程可变性，以及（4）启用女性领导能力的智能行业，以启用其能够定制的行业，从而使能够创建能够创建能够创建的能力，从而使能够创建能够创建的能力，从而使能够创建能够定制的习惯。医疗和其他领域的合作伙伴。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准来评估，被认为是珍贵的支持。
