Abstract: Disclosed are a new porous structure and a method for manufacturing the same. The porous structure is a three dimensional truss structure assembled by crossing a three directional linear wire group having the azimuth of 90 degrees in space, has the light weight while the structural strength and stiffness are high. Moreover, a manufacture process is simple, so costs can be reduced. The three dimensional lattice truss structure consisting of a continuous wire group comprises a first linear wire group arranged in parallel at equal intervals on a plane, and a second linear wire group arranged in parallel at equal intervals by being overlapped with the first linear wire group to have the azimuth of 90 degrees on the first linear wire group, and includes a mesh for forming a fixed rectangular hole by fixing an intersection point of the first and second linear wire groups; and a third wire group crossed in a direction perpendicular to the mesh between the intersection points. In the three dimensional lattice truss structure, only two wires are crossed in all intersection points of the truss structure. The mesh is arranged in multi steps in parallel at equal intervals in a vertical direction on the plane, and the mesh arranged to be adjacent to each other is arranged in multi steps to move in parallel as much as an interval less than a pitch of the tetragonal hole. The three dimensional lattice truss structure is stood, so a plane composed of the mesh is to be a vertical plane. The first first linear wire group and the second linear wire group are oriented, so the form facing the mesh is to be the continuous X-orientation form.

Abstract: The present invention relates to a three-dimensional lattice truss structure which consists of a thin film of a nanometer thickness and a manufacturing method thereof comprising: (a) a step for manufacturing a three-dimensional lattice truss structure by using a resin wire; (b) a step for forming a metal tube by plating or coating a surface of the three-dimensional lattice truss structure with metal; and (c) a step for etching and removing a resin inside the metal tube. The wall thickness of a wire is 100-500 nm, the length of a truss element is 100-1000 μm, and the total size of the three-dimensional lattice truss structure is 1-1000 mm. Therefore, excellent strength can be obtained in comparison with the weight since provided is a three-dimensional lattice truss structure which consists of triple multi-scale.
