Objectives Research is proposed that will advance design and fabrication techniques relating to direct digital manufacturing (DDM), or additive manufacturing of three-dimensional, reconfigurable microwave microsystems. DDM is a layer-by-layer fabrication approach which can combine structural, functional and sacrificial materials in a single build of arbitrary-shaped structures. The work will investigate devices that include new transmission line geometries, deployable 3-D antennas and tunable cavity filters. Mechanical reconfiguration based on DDM-produced shape-shifting surfaces will also be studied.Intellectual Merit DDM has enabled significant technical innovation in a wide range of fields, from bio-medical devices to fuel cells, but utilization in RF/microwave applications is in its infancy. To date, high frequency applications have consisted primarily of the deposition of conductors on conformal surfaces to create antennas and simple interconnects. This project will explore the integration of innovative electronic and mechanical design techniques that are compatible with a low cost, common manufacturing platform to produce 3D microwave systems.Broader Impacts Reversing the loss of high-tech manufacturing jobs is of vital importance to the Nation?s economic security, and thus the outcomes of this project could have significant societal impact. DDM is also a green technology that eliminates material waste associated with subtractive manufacturing and so has a positive impact on environmental sustainability. The outcomes of the research will be integrated into undergraduate education through joint REU activities between the partnering institutions, and also into the graduate curricula at each school. Graduate student exchanges are planned along with summer internships at Sciperio to enhance professional development.

目标 研究将推进与直接数字制造（DDM）或三维可重构微波微系统的增材制造相关的设计和制造技术。 DDM 是一种逐层制造方法，可以将结构材料、功能材料和牺牲材料结合在单个任意形状结构的构建中。这项工作将研究包括新的传输线几何结构、可部署的 3D 天线和可调谐腔体滤波器的设备。还将研究基于 DDM 产生的变形表面的机械重构。 智力优势 DDM 在从生物医疗设备到燃料电池的广泛领域实现了重大技术创新，但在射频/微波应用中的利用还处于起步阶段。迄今为止，高频应用主要包括在共形表面上沉积导体以创建天线和简单的互连。该项目将探索创新电子和机械设计技术的集成，这些技术与低成本、通用制造平台兼容，以生产 3D 微波系统。 更广泛的影响 扭转高科技制造业就业岗位的流失对于国家经济安全至关重要，因此该项目的成果可能会产生重大的社会影响。 DDM 也是一种绿色技术，可以消除与减材制造相关的材料浪费，因此对环境可持续性产生积极影响。 研究成果将通过合作机构之间的 REU 联合活动纳入本科教育，并纳入每所学校的研究生课程。我们计划在 Sciperio 进行研究生交流以及暑期实习，以促进专业发展。
