Current research into 3d printed electronics offers little focus on integration with conventional electronics, describing either fully printed circuits or providing characterization and design of a single circuit element. Therefore in this work, the possibility of combining conductive polymer-based circuit elements with conventional electronics was studied. Characterization at typical operating conditions, interfacing with traditional substrates and potential achievable performance of printed R, C, L elements were investigated with the use of commercially available conductive filaments.
Carbon black doped conductive polymers were found to be most suitable for operating conditions commonly specified for conventional electronics. The use of a Thermoplastic Polyurethane based polymer was found to provide reliable interfacing to conventional gold contacts and good adhesion to conventional substrates. Copper nanowire doped filaments were found to be most suitable for the creation of printed circuit elements due to their low resistivity, however, they were also found to incur severe degradation at the desired operating conditions.
