A method for fabricating a 3D (three-dimensional) structure is disclosed to provide hydrophobicity to a surface of a 3D structure by using a dipping method in which a predetermined-shaped structure is immersed in a molten metal solution. The method includes: immersing a predetermined-shaped structure in a molten metal solution to coat a molten metal material on the surface of the predetermined-shaped structure; anodizing a metal base coated with the molten metal material; coating a polymer material on an outer surface of the metal-coated base to form a negative replica structure; covering an outer surface of the negative replica structure with an outer formation material; and removing the metal-coated base from the negative replica structure and the outer formation material.
