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.

增材制造 (AM) 也称为 3D 打印，是直接从数字文件逐层制造定制零件的过程，无需特定零件的工具相对于传统制造工艺，增材制造可以缩短交货时间。 ，减少浪费，避免供应链中断，并实现前所未有的功能、设计自由度和定制水平，为从航空航天系统到医疗设备等行业带来巨大利益，这一领先工程为美国的繁荣、健康和基础设施带来了巨大利益。 (LEAP-HI) 学术与工业联络机会 (GOALI) 项目支持基础研究，为智能设备建立新的增材制造功能，这些设备可以为个体患者快速定制，并随着患者需求综合性质的变化实现形状的工程改变。该项目需要同时解决材料科学、设计工程和增材制造方面的挑战，以实现先进智能设备的稳健制造——预计到 2025 年市场规模将达到 982 亿美元——从而提高美国在医疗等交叉行业的竞争力此外，该项目为性别研究学者提供了一个机会，可以研究全女性 PI 团队之间的合作过程，并更好地了解如何实现技术和科学进步以及如何支持技术领导者。尽管增材制造技术最近取得了进展，并且对智能设备和活性材料（包括可打印材料）的研究不断增长，但很少有研究人员展示了智能多材料结构和设备的增材制造。通过仔细整合来弥补这一知识差距加工、建模、设计和表征，并通过研究多个焦点之间的复杂相互作用，基本包括：(1) 开发新型聚合物基活性材料，通过填料分级显着增强性能，(2) 开发新型 AM。集成多种材料并根据需要对它们进行功能分级的流程，(3) 开发一种高效、稳健的设计方法，考虑流程的可变性，以及 (4) 对女性领导团队进行人种学分析，有可能对这一领域产生积极影响更广泛的机械工程。预计将能够创建可定制的智能设备，并可由医疗和其他领域的行业合作伙伴将其商业化。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
