  • Method for manufacturing three-dimensional lattice truss structure using flexible linear bodies
    Patent number: 10434564
    Abstract: A method for manufacturing a three-dimensional lattice truss structure using flexible wires, including: arranging a plurality of out-of-plane wires; forming crossing portions between the plurality of out-of-plane wires; inserting a plurality of in-plane wires in the crossing portions; translating the plurality of in-plane wires in the z-direction; and inserting boundary rods in the y- or x-direction inside the plurality of out-of-plane wire groups.
    Type: Grant

  • Method for fabricating ultra-low density three-dimensional thin film structure based on photo-lithography
    Patent number: 9878472
    Abstract: A method for forming an ultra-low density three-dimensional thin film structure made of a solid thin film, including: radiating ultraviolet rays of different patterns in respective predetermined directions to a liquid photosensitive resin bulk so as to harden a portion of the resin bulk; removing the liquid photosensitive resin which is not hardened so as to form a solid photosensitive resin structure; coating the surface of the solid photosensitive resin structure with a thin film; removing the thin film from the outermost surface of the resin bulk so as to expose the solid photosensitive resin; and removing the solid photosensitive resin structure.
