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

这笔赠款为25名职业早期研究人员参加将于2024年3月2日至3日在明尼苏达州明尼阿波利斯市举行的2024年美国物理学会(APS)3月会议上举行的短期课程“添加剂制造的聚合物物理学”提供部分旅费和注册支持。添加制造(AM)技术正在改变产品在业余爱好、原型制作和工业规模上的设计和使用方式。这些技术使减少制造产品所需材料的数量(“物质经济”)以及轻量化努力(减少这些材料的碳足迹)取得进展。个性化产品的能力促进了医疗保健领域的进步，而快速成型缩短了产品上市时间，并允许现场维修关键部件。在基于聚合物的AM方法的开发、控制和应用方面不断进行跨学科创新，对于确保开发新的高精度、高通量AM方法并使其应用于从医疗保健到机器人和航空航天等行业非常重要。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正在出现的AM方法背后的核心聚合物物理基础原理。此外，短期课程将以行业代表和小组讨论为特色，他们将说明AM的核心基础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于建立一个多学科的参与者集合，特别关注来自不被充分代表的背景的职业生涯早期参与者。“添加剂制造的聚合物物理”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、化学和添加剂制造过程的高级表征方面的专家。添加剂制造和生物(包括生物材料和细胞)之间的相互作用以及对印刷结构的独特机械进行建模的专家也将参加。这些专家将主持教学讲座，讲授支持添加剂制造技术的原理，包括热塑性挤出、直接墨水写入(DIW)和嵌入式DIW、生物打印以及层层和体积还原光聚合法。具体主题将集中在实验和计算的作用上，并将讨论传热学、聚合物流变学和流动、聚合物扩散、结晶和纠缠的作用；“油墨”微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；以及在3D打印结构中可以实现的独特机制。该项目的重点是支持早期职业参与者的注册和旅行，预计将带来多样化的早期职业受众。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。

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.
