Claim 19:
20. A method of producing a metal-plastic multi-layered hybrid structure by using laser three-dimensional (3D) printing, the method comprising:
printing a metal structure on a substrate by using a first laser;
patterning an upper surface of the metal structure by using the first laser;
printing a polymer bonding layer on the patterned metal structure by using the first laser; and
printing a polymer structure on the polymer bonding layer by using a second laser having a wavelength longer than a wavelength of the first laser,
wherein the printing of the polymer bonding layer comprises forming an intermediate phase at an interface between the metal structure and the polymer bonding layer, and the intermediate phase has a 3D structure formed by cross-linking.
