The invention discloses a method for manufacturing a three-dimensional periodic structure metamaterial by utilizing the three-dimensional printing technology and belongs to the field of micro machining and microwave technology, aiming at solving the technical problems of poor accuracy and long time consumption in an existing method for manufacturing the metamaterial. The method comprises the following steps: establishing a three-dimensional CAD (computer aided design) model of a metal material structure and a three-dimensional CAD model of a resin material structure of the metamaterial respectively by utilizing three-dimensional modeling software; converting the three-dimensional CAD models into STL (standard template library) formatted files; inputting the STL formatted files into a double-material three-dimensional printer; and printing the metal material structure and the resin material structure of the metamaterial simultaneously by adopting different materials to obtain the three-dimensional periodic structure metamaterial. By utilizing the method, the metamaterial with any three-dimensional periodic units and any facial forms can be manufactured, the manufacturing accuracy is high, the speed is high, and the process is simple.
Description
technical field [0001] The invention relates to a method for producing a three-dimensional periodic structure metamaterial by three-dimensional printing technology, and belongs to the fields of micromachining and microwave technology. Background technique [0002] Metamaterials refer to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have. The interior of the metamaterial has a microstructure of subwavelength size. Through the orderly design of the structure on the key physical scale of the material, it can break through the limitations of some apparent natural laws, so as to obtain the supernormal material function beyond the inherent ordinary properties of nature. Such as negative permittivity, negative magnetic permeability and negative refractive index. [0003] Metamaterials are three-dimensional intersecting structures, and there are different media or metals embedded in the structure, an...
