PURPOSE: A porous electroformed shell for patterning using fiber and a manufacturing method thereof are provided to precisely control the diameter, shape, position, and density of micro pores depending on the various curves of the electroformed shell. CONSTITUTION: A manufacturing method of a porous electroformed shell for patterning using fiber is as follows. A fiber is fitted in the surface of a netative silicone cast. An epoxy is spread on the surface of the negative silicone cast and is hardened. When the epoxy is separated, the fiber is transferred from the negative silicone cast to an epoxy mandrel. A conductive film is formed on the pattern forming plane(20a) of the epoxy mandrel and is electrically conducted. The surface fiber of the epoxy mandrel is eliminated. An electroformed layer(20) is formed by attaching an electroforming metal on the conductive film. Micro pores(21) are formed in holes formed when the fiber is eliminated. The electroformed layer is separated from the epoxy mandrel. |
