Abstract:
1. A method for manufacturing a three-dimensional cellular light structure, comprising: a helical wire forming step of forming 1st, 2nd, 3rd, 4th, 5th and 6th-axis helical wires, each of the helical wires being formed such that the pitch of the helical wires is two times the length of a regular tetrahedron which is a unit cell of the three-dimensional cellular light structure; a two-dimensional Kagome plane forming step of forming a plurality of two-dimensional Kagome planes by assembling the 1st, 2nd and 3rd-axis wires on frames of a frame assembly; a step of fabricating a three-dimensional cellular light structure by assembling the 4th, 5th and 6th-axis wires in out-of-plane directions on two-dimensional Kagome planes consisting of the 1st, 2nd and 3rd-axis wires in each frame.
