Abstract :3D printing, also known as additive manufacturing insert ignore into journalissuearticles values(AM);, is a new technology that allows to design and production of objects or functional devices in a single process. 3D technology has expanded its ability to utilize as scientific research and medical application, recently. As this technology becomes more widespread, 3D printing systems become more affordable. Especially, the 3D printing method has been used to perform electrodes production for electrochemical applications in the last five years. Commonly known 3D printing filaments are polylactic acid insert ignore into journalissuearticles values(PLA); or acrylonitrile butadiene styrene insert ignore into journalissuearticles values(ABS);. Thanks to these conductive materials, it is possible to modify their material properties to enhance conductivity or other specifications. In this study, investigation of the electrochemical performance of the conductive PLA is conducted by electroplating of Cu on the surface.   In the constant voltage value, current density value of Cu coated electrode is increased three times. Moreover, the usability of conductive PLA as an electrical circuit element or electrochemical energy conversion electrode is investigated. According to the obtained results, in LSV measurements, uncoated PLA and Cu coated PLA has a maximum current of 0.9A and 2.8A at a constant voltage, respectively. In the CV measurement, kinetic performance and electrical conductivity properties are improved in Cu coated PLA sample.  In CV measurements, for different scan rate between 50 mV to 200mV is observed that the current value of Cu coated PLA is increased for all measurements. In Cu coated PLA, significant improvement in conductivity is obtained in Electrochemical Impedance Spectroscopy Analysis insert ignore into journalissuearticles values(EIS);.
