3 3 FABRICATION METHOD OF 3 DIMENSIONAL STRUCTURE WITH GYROID TRIPLY PERIODIC MINIMAL SURFACES BASED ON BEAD ARRAYS

摘要

The present invention relates to a method for manufacturing a three-dimensional structure having a 3-period minimum curved surface (TPMS) based on a bead arrangement, and more particularly, to a geometric shape of a bead arrangement for realizing a gyroid three-period minimum curved surface and a method thereof. The three-dimensional structure manufacturing method is a manufacturing method of interconnecting beads after forming a bead array by contacting a plurality of beads in a predetermined pattern, wherein the bead arrangement is (a) a plurality of unit layer patterns are repeatedly stacked, (b ) is formed by bonding contact portions between all beads constituting a plurality of unit layer patterns, and the unit layer pattern has a triangular bead arrangement consisting of one central bead (C) and three branch beads (S) having the same diameter. It is characterized in that the unit cell patterns of are spaced apart from each other to form a secret house rule arrangement. In this case, the unit layer pattern may have a single-layer or multi-layer structure. According to the present invention, other three-dimensional structures having a gyroid or double gyroid curved surface and a three-dimensional thin-film porous structure using the same as a sacrificial structure can also be mass-produced. can be further expanded.
