3D Additive Multiscale Manufacturing Using Near-Field Ultrafast Laser

这项拨款为开发一种创新的3d增材制造工艺提供资金，该工艺能够生产纳米分辨率的均匀金属和聚合物特征，用于光学、光子学、生物材料和其他领域。该项目将结合最近开发的光学陷阱辅助纳米图像化方法提供的图像化分辨率和缩放优势，以及超快多光子聚合处理的3-D添加剂能力。为了实现这一目标，有必要对这些过程有更深入的基本理解，这将通过旨在确定实验参数与沉积材料的最终性质之间的关系的受控实验来获得。有了这些详细的知识，该项目将继续开发一个工作模型，预测如何控制特征尺寸和材料属性。如果成功，这项研究将对许多不同的应用领域产生深远的影响，这些领域需要多尺度和多功能的3d架构来推进功能，如光子材料、光电子、微流体、组织工程等。通过出版物和国际演讲在这些领域的广泛传播将确保研究人员从我们的研究中获得广泛的利益。据设想，这项研究是普林斯顿大学和德国埃尔兰根-纽伦堡大学先进光学技术学院（un - saot）研究人员在3d激光制造方面进行新型国际合作的种子。为此目的，已拨出资金支持前往un - saot的旅行，在那里其他研究人员和学生将接受这项发展中的技术的培训。

This grant 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. The project will 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. In order to achieve this goal, it is necessary to attain a deeper fundamental understanding of these processes, which will be gained through controlled experiments that are aimed at determining the relationship between the experimental parameters and the resulting properties of the deposited materials. Armed with this detailed knowledge, the project will then proceed to develop a working model that predicts how to control feature size and material properties.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. It is envisioned that this research is a seed for a novel 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 other researchers and students will be trained in this developing technology.
