While promising, and demonstrating feasibility of the high-speed/high-resolution E-jet concepts, most previous E-jet activities have focused on the printing capabilities of a single nozzle with a single material solution. Heterogeneously integrated functional electronic systems often require multiple materials (polymers, metals, biological material) to be present and collocated on the same substrate. For this reason, my research focuses on developing a toolbit which can handle multiple materials. The images below show several example application of multimaterial E-Jet deposition system
The multimaterial toolbit is an integrated part of a Desktop E-jet Printer, a low cost micro/nano-manufacturing platform. My research work involves both the design and fabrication of the multisyringe toolbit as well as the development of the Desktop System. This research work is a multidisciplinary project involving mechanical design, electronics and instrumentation, feedback control, and user interface design.
