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.

多尺度多功能结构在自然界中发现，并在许多工程应用中使用。但是，事实证明，使用传统制造技术制造此类结构非常困难，部分是因为它们的复杂结构需要在许多长度上开发。为了应对这一挑战，这项教师早期职业发展（职业）计划项目将通过有选择性的冻结和纳米材料的原位冰上冰上的冻结纳米印刷（FNP）方法来研究多功能多功能的多孔结构。合并的实验和建模方法将用于了解FNP中的基本机制，并阐明参数过程结构 - 建筑 - 理性关系。该研究将贡献一个3D打印过程，该过程从根本上可以解锁结构和功能性能，并在能源，健康，环境，航空，航空，汽车和消费产品等领域提供工业应用。 因此，该项目对经济福利，国家卫生和安全产生积极影响。教育目标是激发高中生，吸引新生级的本科生参加该领域，培训研究生，并通过基于3D打印技术的动手教育和制造创新向公众提供宣传。活动包括发布开源3D打印系统；开发可访问的讲座；以及修补林营研讨会，自由伙伴关系计划和3D打印研讨会的组织。该职业项目将着重于冻结纳米印刷（FNP）技术，以制造多功能和多功能结构。中心前提是可以通过原位冰冰进行微观结构，而宏观结构可以通过喷墨打印来控制。如果成功的话，该项目将显着提高对FNP过程中复杂现象的科学理解，包括1）了解高度敏感的多维纳米材料与印刷喷嘴的相互作用，以及墨水组成和过程参数如何影响下降的形成，并最终影响产生的互联网的跨度，2）跨度的构成，2）跨度的构成方式。在液滴冰的过程中，以及复杂行为如何影响微观结构特性，以及3）研究过程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性。通过基于动手的教育活动，该项目将为从K-12到研究生级的学生提供令人兴奋的课程材料和实验室项目。与学生日常生活相关的课程前学院的宣传将扩大少数群体和代表性不足的团体的参与。通过教学和研究为本科生和研究生量身定制的课程将激发他们对科学和工程学的终身兴趣。社区宣传将有助于提高3D印刷技术的认识和采用，并使高级制造业民主化。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评估标准来评估值得支持的。
