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

这项资助为25名早期职业研究人员参加2024年3月2日至3日在明尼苏达州明尼阿波利斯举行的美国物理学会（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）技术正在改变产品的设计方式，并在业余爱好、原型设计和工业规模上使用。这些技术在减少制造产品所需的材料数量（“材料经济”）以及轻量化努力（减少这些材料的碳足迹）方面取得了进展。个性化产品的能力推动了医疗保健领域的进步，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。在基于聚合物的增材制造方法的开发、控制和应用方面持续的跨学科创新对于确保开发新的高精度、高通量增材制造方法并使其应用于医疗保健、机器人和航空航天等行业至关重要。短期课程将通过包括互动元素在内的讲座，教授与会者基于核心聚合物物理原理的几种关键已建立和新兴增材制造方法。此外，短期课程将邀请行业代表和一个小组，他们将说明增材制造的核心基础物理和化学原理如何使应用具有现实世界的影响。招聘和广告工作将侧重于建立一个多学科的参与者群体，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聚合物物理学部（DPOLY）提供，并将汇集聚合物物理、计算建模、光学、化学和增材制造工艺高级表征方面的专家。增材制造与生物学（包括生物材料和细胞）之间相互作用的专家以及对印刷结构的独特力学建模的专家也将参加。这些专家将讲授增材制造技术的基本原理，包括热塑性挤出、直接油墨书写（DIW）和嵌入式DIW、生物打印以及层接层和体积容器光聚合。具体主题将集中在实验和计算的作用，并将讨论传热，聚合物流变和流动，聚合物扩散，结晶和缠结的作用；“油墨”微观结构与可印刷性的关系光学、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，预计将吸引多样化的早期职业受众。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识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.
