Three-dimensional (3D) printing technology presents a higher flexible technique to produce different complex geometric shapes compared to conventional manufacturing. This technology is known as additive manufacturing (AM) may be also suitable for industrial production. AM method is widely used in different areas, including construction, medicine, energy, and electrochemistry, recently. Polymeric materials such as polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS) filaments are used in the 3D printing process. In this study, the conductive polymeric anode electrodes are prepared using 3D printing method. Then, these electrodes are coated with Pt in different thicknesses (0.5, 1, 1.5, and 2µm) by the electron beam evaporation (EBM) method. A thin Cr adhesion layer (20nm) is used to improve the adhesion of the Pt coating on the sample surface. After the completion of the coating process, the polymeric electrodes are named as Pt-0.5, Pt-1, Pt-1.5, and Pt-2. Pt coated 3D printed polymeric electrodes have been physically characterized by using Field Emission Scanning Electron Microscopy (FE-SEM), FE-SEM/Energy Dispersive X-Ray Spectroscopy (FE-SEM/EDX), FE-SEM mapping, and X-Ray Powder Diffraction (XRD) techniques. Cycling Voltammetry (CV), Linear Sweep Voltammetry (LSV), Electrochemical Impedance Spectroscopy (EIS), and Chronoamperometry (CA) analysis of the Pt coated electrodes have been conducted to evaluate their electrochemical performance.
