A mechanical metamaterial comprising a chiral structure and a reentrant structure repeatedly layered to form a 3D structure with improved compressive response is disclosed. The 3D structure of the present invention is a metamaterial which can be perfectly and easily produced by a photocuring 3D printing process without any internal support. The introduction of modified carbon nanotubes into the printing composite material improves the compression resistance and impact resistance of the products and increases the service life through the special periodic structure. The application of 3D printing technology in fabricating mechanical metamaterials can break through the processing limitation of traditional processing technology or microelectronics manufacturing technology to make three-dimensional periodic structures.
