Rapid prototyping of devices by 3D printing has become an indispensable tool in science and engineering research; however, conventional instruments are unable to create custom micro- and nanoscale structures with short turnaround times. This project seeks to accelerate research for a diverse team of investigators in southeast Michigan by acquiring a Nanoscribe Photonic Professional GT2, a state-of-the-art nanoscale 3D printing and maskless lithography system that will be the first of its kind in Michigan’s lower peninsula. The instrument will be used by eighteen faculty investigators across seven departments at Wayne State University (WSU) and six other regional universities. The GT2 will be housed at the WSU Nanofabrication Facility (nFab), a 5,000 sqft clean room that provides class 100 air filtration to reduce defects, filtered lighting, and access to other instruments for pre- and post-print processes. The management plan seeks to maximize the user base by maintaining modest fees and a remote service model. The GT2 will accelerate the micro- and nanofabrication capabilities at WSU while strengthening its role in the regional network of device manufacturing hubs in southeast Michigan. Over its 15-year lifespan, we anticipate the instrument will be used in research by 400 graduate students, 400 undergraduates, and 80 postdocs, including women and underrepresented students and junior scholars. It will help train 1,000 additional students by incorporating rapid nanoscale prototyping into graduate and undergraduate courses on microfabrication and design. Hands-on exposure to 3D CAD and microfabrication is critical to workforce training in Michigan, where manufacturing makes up 20% of the total economy. Three of six partner universities are primarily undergraduate institutions, serving 7,500 engineering students. Lastly, the GT2 will facilitate community outreach through the WSU STEM Innovation Learning Center, Detroit-area science fair projects, and the annual STEM day for K-12 students. The GT2 will complement WSU’s other NSF-funded optical, electron, and atomic force microscopes to provide an in-depth, hands-on understanding of micro design workflow to the Detroit community. The Nanoscribe Photonic Professional GT2 uses 2-photon polymerization (2PP) to print 3D structures with a resolution of 200 nm in a variety of materials. Three key instrument capabilities will overcome challenges faced by researchers. The GT2: (1) enables fabrication of 3D structures with unconstrained geometries at 1000X smaller length scales than conventional 3D printers, enabling systematic studies and exploitation of physics at 200 nm-100 µm length scales; (2) is compatible with a variety of custom resins to support a diversity of projects, including nanoparticle embedded or biodegradable materials; and (3) enables rapid iteration on experimental device designs, which is key to accelerating both hypothesis-driven and applied research. The GT2 will enable synergistic advances in 3 scientific thrusts. 1) Colloidal assembly will address unanswered questions of how 3D structures control the assembly of biomembranes, nanocolloids, and droplets at length scales from 200 nm to 100 µm. 2) Deterministic porosity will seek to understand how geometrically controlled, sub-µm to µm mesostructures change bulk polymer properties, addressing contemporary issues such as the volume expansion in solid-state battery electrodes, and the role of porosity gradients in molecular filtration. 3) 3D MEMS will engineer 3D structures to extend or improve the performance of microsensors and actuators, contributing novel approaches for planetary seismometers, in-vivo microrobots, image-activated cell sorters, and optical signal processors. Outcomes within three thrusts will advance knowledge in diverse applications including energy storage, lab on a chip, tissue engineering, neural interfaces, colloidal manufacturing, drug delivery, robotics, sensors, and metamaterials. Projects will also enhance the field of 2PP fabrication, including machine-learning optimization of CAD designs, and characterization of 2PP optical components by interferometry. Success will be evaluated by publications and the number and diversity of 3D CAD designs disseminated to the research community.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.

通过3D打印对设备进行快速原型已成为科学和工程研究中必不可少的工具。但是，传统的仪器无法在短时间内创建自定义的微观和纳米级结构。该项目旨在通过收购Nanoscribe Photonic Professional GT2（一种最先进的纳米级印刷品和无面层岩性摄影系统，这将是Michigan下半岛的最早的纳米型纳米级印刷和无面具的岩性系统，该项目旨在为密歇根州东南部的一个研究人员的研究团队加速研究。该工具将由韦恩州立大学（WSU）和其他六所地区大学的七个部门的18名教师调查员使用。 GT2将安置在WSU纳米制造设施（NFAB），这是一个5,000平方英尺的清洁室，可提供100级空气滤清器，以减少缺陷，过滤的照明以及访问其他仪器以进行预印过程和后印刷过程。管理计划旨在通过维护适中的费用和远程服务模型来最大化用户群。 GT2将加速WSU的微型和纳米工艺能力，同时增强其在密歇根州东南部设备制造中心的区域网络中的作用。在其15年的寿命中，我们预计该乐器将用于400名研究生，400名本科生和80个博士后，包括女性和代表性不足的学生和初中学者。它将通过将快速的纳米级原型纳入微观加工和设计的研究生和本科课程中来帮助培训1,000名学生。动手接触3D CAD和微加工对于密歇根州的劳动力培训至关重要，在密歇根州，制造业占总经济的20％。六所伙伴大学中有三所是小学的本科机构，为7,500名工程专业的学生提供服务。最后，GT2将通过WSU STEM创新学习中心，底特律地区科学博览会项目和K-12学生的年度STEM日促进社区宣传。 GT2将补充WSU的其他NSF资助的光学，电子和原子力显微镜，以向底特律社区提供对微观设计工作流程的深入，动手的理解。 Nanoscribe Photonic Professional GT2使用2光子聚合（2pp）在各种材料中以200 nm的分辨率打印3D结构。研究人员面临的三个关键仪器能力将克服挑战。 GT2：（1）可以在1000倍尺度上与常规3D打印机小的长度尺度上制造3D结构，从而在200 nm-100 µm长度尺度下进行系统研究和对物理的开发； （2）与各种定制树脂兼容，以支持各种项目，包括嵌入纳米颗粒或可生物降解材料； （3）实现实验设备设计的快速迭代，这是加速假设驱动和应用研究的关键。 GT2将在3个科学推力中实现协同进步。 1）胶体组件将解决3D结构如何控制生物膜，纳米胶体和液滴的未解决问题，该问题的长度从200 nm到100 µm。 2）确定性的孔隙度将寻求了解几何控制，亚µm到µM介质结构如何改变散装聚合物特性，从而解决当代问题，例如固态电池电极的体积扩展以及孔隙率梯度在分子过滤中的作用。 3）3D MEMS将设计3D结构以扩展或改善微传感器和执行器的性能，从而为行星地震米，体内微型机器人，图像激活的细胞分类器和光信号处理器提供新的方法。三个推力内的结果将推进在潜水员应用中的知识，包括储能，芯片上的实验室，组织工程，神经界面，胶体制造，药物输送，机器人，传感器和超材料。项目还将增强2PP制造的领域，包括对CAD设计的机器学习优化，以及通过干涉测量法对2PP光学组件进行表征。成功将通过出版物以及3D CAD设计的数量和多样性进行评估。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，通过评估被认为是珍贵的支持。
