Scientific and technological achievements became intesivelly used on the practice when their application became economically efficient. In this study, we demonstrated the potential of using filament 3D printing technologies for repairing multielectrode arrays (MEAs), a key expensive component of most in vitro bioelectronic devices. We present a method for restoring the functionality of MEAs after its reference (counting) electrode failure by replacing them with a special 3D printed holder equipped with a tiny platinum strip. The obtained results can be used for an extension of the life cycle of MEAs, making the applications of bioelectronic technologies more accessible for solving actual problems in medicine and biology. Keywords: multielectrode arrays, impedance spectroscopy, 3D printing, repair.
