Multiscale, multifunctional porous structures are found in nature and used in many engineering applications. However, it has proven extremely difficult to fabricate such structures using traditional manufacturing techniques, partially because their intricate structures need to be developed over many length scales. To address this challenge, this Faculty Early Career Development (CAREER) Program project will investigate a freeze nano printing (FNP) approach through selectively freezing and in situ ice-templating of nanomaterials to fabricate multiscale, multifunctional porous structures. A combined experimental and modeling methodology will be used to understand the fundamental mechanism in FNP and elucidate the parameter-process-structure-property relations. The research will contribute a 3D printing process that can fundamentally unlock structural and functional properties and lead to industrial applications in areas such as energy, health, environment, aerospace, automotive, and consumer products. As such, the project positively impacts economic welfare, national health and security. The educational objective is to inspire high school students, attract freshman-level undergraduate students to the field, train graduate students, and provide outreach to the general public through hands-on education and manufacturing innovation based on 3D printing technologies. Activities include publishing an open-source 3D printing system; development of web-accessible lectures; and organization of a TINKER camp workshop, a Liberty Partnerships program, and a 3D printing symposium. This CAREER project will focus on freeze nano printing (FNP) technology to fabricate multiscale and multifunctional porous structures. The central premise is that the microscale structure can be manipulated by in situ ice-templating, while the macroscale structure can be controlled by inkjet printing. If successful, this project will significantly advance scientific understanding of the complex phenomena in FNP process, including 1) understanding how the high-aspect-ratio multidimensional nanomaterials interact with printing nozzle, and how the ink composition and process parameters affect the drop formation, and ultimately influence the property of the produced macrostructure, 2) elucidating the mechanism of how the multidimensional nanomaterials interact with ice-crystals during the droplet-wise ice-templating process, and how the complex behavior affects the microstructural property, and 3) studying the relation between the process parameters and the interfacial structures of the multiple materials, and how the interfacial structures influence the multifunctionality. Through hands-on-based educational activities, this project will provide exciting course materials and lab projects to students from K-12 to graduate-level. Outreach to pre-college institutes with curriculum relevant to students' daily lives will broaden participation of the minority and underrepresented groups. Curriculum tailored to the undergraduate and graduate students through teaching and research will inspire their lifelong interest in science and engineering. Community outreach will help promote awareness and adoption of 3D printing technologies and democratize advanced manufacturing.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.

多尺度、多功能的多孔结构在自然界中广泛存在，并在许多工程应用中得到应用。然而，事实证明，使用传统制造技术制造这种结构极其困难，部分原因是它们的复杂结构需要在许多长度尺度上开发。为了应对这一挑战，学院早期职业发展(CALEAR)计划项目将研究冷冻纳米打印(FNP)方法，通过选择性冷冻和原位冰模板化纳米材料，以制造多尺度、多功能的多孔结构。实验和模拟相结合的方法将被用来理解FNP的基本机制，并阐明参数-过程-结构-性质的关系。这项研究将有助于3D打印过程，可以从根本上解锁结构和功能特性，并导致在能源、健康、环境、航空航天、汽车和消费品等领域的工业应用。因此，该项目对经济福利、国民健康和安全产生了积极影响。教育目标是通过基于3D打印技术的实践教育和制造创新，激励高中生，吸引大一水平的本科生进入该领域，培养研究生，并向普通公众提供外联服务。活动包括出版开放源码的3D打印系统；开发可在网上访问的讲座；以及组织修补工营讲习班、自由伙伴关系方案和3D打印研讨会。这个职业项目将专注于冷冻纳米打印(FNP)技术，以制造多尺度和多功能的多孔结构。中心前提是微观结构可以通过原位冰模板操纵，而宏观结构可以通过喷墨打印进行控制。如果成功，该项目将极大地促进对FNP过程中复杂现象的科学理解，包括1)了解高深宽比多维纳米材料如何与打印喷嘴相互作用，以及油墨组成和工艺参数如何影响液滴的形成，并最终影响所产生的宏观结构的性能；2)阐明多维纳米材料在液滴状冰模板过程中如何与冰晶相互作用的机理，以及复杂的行为如何影响微观结构特性；3)研究工艺参数与多种材料的界面结构之间的关系，以及界面结构如何影响多功能。通过亲身实践教育活动，该项目将为从K-12到研究生水平的学生提供令人兴奋的课程材料和实验项目。向具有与学生日常生活有关的课程的大学预科机构进行外联，将扩大少数群体和代表性不足群体的参与。通过教学和研究为本科生和研究生量身定做的课程将激发他们对科学和工程的终身兴趣。社区外展将有助于提高人们对3D打印技术的认识和采用，并推动先进制造的民主化。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。
