This EArly-concept Grant for Exploratory Research (EAGER) award provides funding to develop an innovative 3-D additive manufacturing process capable of producing uniform metal and polymer features with nanometer resolution for applications in optics, photonics, biomaterials and other areas. Here, we propose to combine the patterning resolution and scaling benefits provided by the recently developed optical trap assisted nanopatterning method with the 3-D additive capabilities of ultrafast multiphoton polymerization processing. However in order to achieve this goal, it is necessary to attain a deeper understanding of these processes and demonstrate the feasibility of such a combined approach. To this end, this proposal will focus on experimentally and numerically probing fundamental proof?]of?]principle questions related to the compatibility of ultrafast laser processing and polymer precursor solutions with optically trapped microspheres, and the ability to polymerize precursor solutions in the vicinity of microspheres without contamination or redeposition. Numerical studies will include finite difference time domain simulations for optical propagation through the liquid solution and polystyrene microspheres. Whereas, experiments will use both in situ imaging during laser processing and ex situ characterization to identify the material response.If successful, this research will have a profound impact on a number of diverse application areas where multiscale and multifunctional 3-D architectures are needed to advance functionality, such as in photonic materials, optoelectronics, microfluidics, tissue engineering, etc. Broad dissemination in these areas through publications and international presentations will ensure researchers gain widespread benefit from our studies. But perhaps more importantly, the success of this research will provide a demonstration of feasibility that is necessary to secure funding through traditional vehicles in order to further develop this potentially transformative materials processing approach. Finally, we envision this research as a seed for an international collaboration between researchers at Princeton and University of Erlangen-Nurenberg, School of Advanced Optical Technologies (UEN-SAOT) in Germany for 3-D laser based manufacturing. To this end, funds have been allocated to support the travel to UEN-SAOT where the PIs will help train other researchers and students in this developing technology.

这项探索性研究的早期概念赠款（急切）奖提供了资金，以开发创新的3-D增材制造工艺，能够生产具有纳米分辨率的均匀金属和聚合物特征，以用于光学，光子学，生物材料和其他领域的应用。在这里，我们建议将最近开发的光学陷阱辅助纳米图案方法提供的模式分辨率和缩放效益与超快多局部聚合处理的3-D添加功能相结合。但是，为了实现这一目标，有必要更深入地了解这些过程，并证明这种合并方法的可行性。为此，该建议将集中在实验和数值探测的基本证据上？]的主要问题？数值研究将包括通过液体溶液和聚苯乙烯微球的光学传播的有限差时间域模拟。 Whereas, experiments will use both in situ imaging during laser processing and ex situ characterization to identify the material response.If successful, this research will have a profound impact on a number of diverse application areas where multiscale and multifunctional 3-D architectures are needed to advance functionality, such as in photonic materials, optoelectronics, microfluidics, tissue engineering, etc. Broad dissemination in these areas through publications and international presentations will ensure researchers gain我们的研究广泛受益。但是，也许更重要的是，这项研究的成功将提供可行性的证明，这对于通过传统车辆获得资金是必要的，以便进一步开发这种潜在的变革性材料处理方法。最后，我们将这项研究视为普林斯顿大学研究人员与德国高级光学技术学院（UEN-SAOT）研究人员之间进行国际合作的种子，以基于3-D激光的制造业。为此，已经分配了资金来支持前往Uen-Saot的旅行，PIS将帮助培训其他研究人员和学生在这项发展中的技术。
