Claim:
A method of manufacturing a truss structure using multi-point pins, comprising: providing an apparatus for manufacturing a truss structure using multi-point pins, the apparatus comprising: a metal plate having an outer frame and a plurality of perforations formed inside the outer frame, the perforations having a same shape; clamps pressing upper and lower sides of the outer frame to hold the metal plate; an upper die comprised of an upper plate; and a plurality of upper multi-point pins arranged under a lower surface of the upper plate in series in rows and columns, the upper die pressing the metal plate downwards; and a lower die comprised of a lower plate; and a plurality of lower multi-point pins arranged on an upper surface of the lower plate in series in rows and columns, the lower die pressing the metal plate upwards, wherein the metal plate comprises a plurality of first points formed at positions that vertically correspond to the upper multi-point pins, and a plurality of second points formed at positions that vertically correspond to the lower multi-point pins, the first points being extended downwards by pressure applied thereto from the upper multi-point pins, and the second points being extended upwards by pressure applied thereto from the lower multi-point pins; wherein heights of ends of the upper multi-point pins differ from each other or heights of ends of the lower multi-point pins differ from each other; machining the metal plate in a two-dimensional net shape by forming perforations having a same shape in the metal plate; clamping the metal plate by pressing upper and lower sides of an outer frame of the metal plate using clamps; and forming the truss structure having a three-dimensional shape through application of pressure to the metal plate using the upper die and the lower die of the apparatus to extend the first points of the metal plate downwards using the upper multi-point pins of the upper die and to extend the second points of the metal plate upwards using the lower multi-point pins.
