Original Abstract

tMajor efforts for the advancement of additive manufacturing are lately focused on the development ofmulti-material 3D-printing (mMat-3DP) methods which can enable the fabrication of complete devicesin a single printing process combining materials with different properties (structural, functional, con-ductive, etc.). Printing conductive (metal and non-metal) materials with low-energy-consuming andeconomical methods is of particular interest since it would facilitate the production of electrodes, cat-alytic surfaces and electronic circuitry in general for countless applications. In order to contribute to thefuture vision of mMat-3DP, we wish to show here an economical method to selectively deposit differ-ent conductive materials (metal and conductive polymer) by means of electrochemical driving forces.A custom-made electrochemical liquid dispenser with embedded electrodes is used to electrodepositselectively a metal (Cu), a conductive polymer (polyaniline), or a combination of the two, with bothprecursors present simultaneously and conveniently in the common electrolytic bath. Combining the3D-patterning ability of a desktop 3D-printer with a concurrent control of the electrochemical process,selective deposition is demonstrated over a conductive graphite foil used as the cathode. Printing andelectrochemical parameters have been optimized using scanning electron microscopy and energy disper-sive X-ray spectroscopy to characterize the printed structures. The electrochemical 3D-printing method,being inherently low-cost, scalable and compatible with electrode fabrication methods shall find a broadscope of applications.
