Travel Support: A Short Course on The Polymer Physics of Additive Manufacturing; 2024 American Physical Society (APS) Meeting; Minneapolis, Minnesota; 2-3 March 2024

该补助金为25名早期职业研究人员参加将于2024年3月2日至3日在明尼苏达州明尼阿波利斯举行的2024年美国物理学会（APS）3月会议上举行的短期课程“增材制造的聚合物物理学”提供部分旅行和注册支持。增材制造（AM）技术正在改变产品在业余爱好、原型设计和工业规模上的设计和使用方式。这些技术正在减少制造产品所需的材料量（“材料经济”）以及轻量化努力（减少这些材料的碳足迹）方面取得进展。个性化产品的能力推动了医疗保健的进步，而快速原型设计缩短了产品上市时间，并允许对关键部件进行现场维修。在基于聚合物的AM方法的开发、控制和应用方面的持续跨学科创新对于确保新的高精度、高通量AM方法的开发并使其应用于从医疗保健到机器人和航空航天的行业非常重要。短期课程将通过包括互动元素在内的讲座向与会者讲授几种关键的已建立和新兴AM方法的核心聚合物物理学原理。此外，短期课程将包括行业代表和一个小组，他们将说明AM的核心物理和化学原理如何使应用程序具有现实世界的影响。招聘和广告工作将集中在建立一个多学科的参与者，特别关注来自代表性不足背景的早期职业参与者。“增材制造的聚合物物理”短期课程将通过APS聚合物物理部门（DPOLY）提供，并将汇集聚合物物理，计算建模，光学，化学，和先进的增材制造工艺表征。增材制造和生物学（生物材料和细胞）之间的相互作用以及打印结构独特力学建模方面的专家也将参加。这些专家将领导增材制造技术基础原理的教学讲座，包括热塑性挤出，直接墨水书写（DIW）和嵌入式DIW，生物打印以及逐层和体积缸光聚合。具体的主题将集中在实验和计算的作用，并将讨论传热，聚合物流变学和流动，聚合物扩散，结晶和缠结的作用;“墨水”微观结构和可印刷性之间的关系;光学，光聚合和反应动力学的作用;以及可以在3D打印结构中实现的独特力学。该项目的重点是支持早期职业参与者的注册和旅行，预计将导致多样化的早期职业观众。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

This grant provides partial travel and registration support for the attendance of 25 early-career researchers to the short course 'Polymer Physics of Additive Manufacturing' to be held at the 2024 American Physical Society (APS) March Meeting in Minneapolis, Minnesota, 2-3 March 2024. Additive manufacturing (AM) techniques are transforming the way products are designed and used at the hobby, prototyping, and industrial scales. These techniques are enabling advances in reducing the amount of material required to manufacture products (‘material economy’) as well as in light-weighting efforts (reducing the carbon footprint of these materials). The ability to personalize products has led to advances in healthcare, while rapid prototyping decreases product time-to-market and allows field-based repairs of critical parts. Continued interdisciplinary innovation in the development, control, and application of polymer-based AM methods is important to ensure the development of new high-precision, high-throughput AM approaches and enable their application to industries from healthcare to robotics and aerospace. The short course will teach attendees the core polymer physics-based principles underlying several key established and emerging AM methods via lectures including interactive elements. Additionally, the short course will feature industry representatives and a panel who will illustrate how the core underlying physics and chemistry principles of AM enable applications with real-world impact. Recruitment and advertising efforts will focus on building a multidisciplinary set of participants, with a special focus on early-career participants from underrepresented backgrounds.The 'Polymer Physics of Additive Manufacturing' short course will be delivered through the APS Division of Polymer Physics (DPOLY) and will bring together experts in the polymer physics, computational modeling, optics, chemistry, and advanced characterization of additive manufacturing processes. Experts in the interplay between additive manufacturing and biology (both biomaterials and cells) and in modeling the unique mechanics of printed structures will also participate. These experts will lead teaching lectures on the principles underpinning additive manufacturing techniques including thermoplastic extrusion, direct ink writing (DIW) and embedded DIW, bioprinting, and both layer-by-layer and volumetric vat photopolymerization. Specific topics will focus on the role of both experiment and computation and will discuss the roles of heat transfer, polymer rheology and flow, polymer diffusion, and crystallization and entanglements; the relationship between 'ink' microstructure and printability; the roles of optics, photopolymerization, and reaction kinetics; and the unique mechanics that can be achieved in 3D printed structures. The focus of this project on supporting registration and travel for early career attendees is expected to lead to a diverse early-career audience.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.
