Optimization of Nozzle Head Toolpath and Component Shape Library in Printed Electronics
Abstract. Additive Manufacturing (AM) based Printed Electronics (PE) is a new area where electronic components and circuits are printed directly on substrates using additive methods. The direct deposition of electrically conductive materials and associated components makes it convenient to print ultra-thin components on a variety of substrates including glass, silicon and plastic. These inherent qualities of metal powder deposition using a nozzle head makes AM based Printed Electronics a very promising manufacturing process in the area of electronic sensors and sensor networks. At present, AM based PE is a labor intensive and manual process wherein decisions are made based on the expertise and judgment of the PE designer/engineer at different stages of the process. This manual intervention at almost every step of the process increases the overall production time and also results in issues related to the consistent quality of parts. Currently, researchers are working in the area of PE for developing new materials, standards, file formats, component shapes and optimization of the nozzle head travel etc. to establish PE as the mainstream process in the electronic sensor community. Optomec has developed a proprietary Aerosol Jet Process which is able to print electronic components on different planar and non-planar substrates using a layered approach. Palo Alto Research Center (PARC) has also developed a jet printing process for manufacturing organic semiconductors and conductors.
