Abstract: The present disclosure provides a method and a system for manufacturing a flexible transparent conductive film with an embedded metal material. The method comprises the steps of sequentially printing metal nanowire grids and metal grids with a large aspect ratio on a printing substrate through an electric field driven micro-nano 3D printing method, and forming a composite conductive electrode of the metal grids and the metal nanowire grids; performing conductive treatment on the composite conductive electrode to obtain an electrode material; and embedding the electrode material into a photoresist, separating the photoresist embedded with the electrode material from the printing substrate, and removing the printing substrate to obtain a conductive film, wherein the metal nanowire grids are formed by printing the metal nanowires, and the metal grids with a large aspect ratio are formed by printing nano metal paste.
