  • Publication number: 20210308949
    Abstract: Disclosed is a 3-D printing apparatus. The apparatus includes an ink output module including an ink supply unit having an ink for forming an electrode portion, electrolyte or packaging portion received therein and an ink discharge unit coupled to the ink supply unit; a driving unit having the ink output module mounted thereon to move the ink output module in an X, Y, Z axis direction with respect to a substrate where a supercapacitor or secondary battery will be formed; a dispenser connected to the ink supply unit to supply gas having controlled pressure to the ink supply unit through a gas supply tube and to supply the ink within the ink supply unit through the ink discharge unit; and a controller controlling the output of the ink by transmitting a control command for fabricating the supercapacitor or the secondary battery to the dispenser and the driving unit.
