Method for manufacturing three-dimensional lattice truss structure using flexible linear bodies

A method for manufacturing a three-dimensional lattice truss structure using flexible wires comprising a plurality of out-of-plane wires and a plurality of in-plane wires, the method comprising the steps of:

• (a) arranging the plurality of out-of-plane wires such that at least any one end forms a free end which is movable in x- and y-directions on an xy plane, and the other end forms a fixed end which is restrained from moving in the x- and y-directions on the xy plane in a state in which the plurality of out-of-plane wires are spaced apart from each other at a predetermined interval (Dxy);
• (b) forming crossing portions between the plurality of out-of-plane wires by switching the free ends of adjacent out-of-plane wire groups, among a plurality of out-of-plane wire groups selected in the y- or x-direction, in the x- or y-direction on the xy plane;
• (c) inserting the plurality of in-plane wires in the y- or x-direction in the crossing portions in a state in which the free ends of a plurality of out-of-plane wire groups, among a plurality of out-of-plane wire groups selected in the x- or y-direction, are integrally moved to cross each other in the x- or y-direction;
• (d) translating the plurality of in-plane wires in the z-direction in a state in which the free ends of the plurality of out-of-plane wires which were moved to cross each other in step (c) are returned to the original positions thereof;
• and
• (e) inserting boundary rods in the y- or x-direction inside the plurality of out-of-plane wire groups which are selected from the y- or x-direction but not switched in step (b), wherein
• orientations are defined on the basis of an x, y and z orthogonal coordinates system, a cycle of steps (b) to (e) is repeatedly performed, and the plurality of in-plane wires are arranged in the z-direction to be spaced apart from each other at a predetermined interval (Dz).
