Zusammenfassung:	The present invention relates to a method for manufacturing a gas turbine vane, and more specifically, to a method for manufacturing a gas turbine vane using a hybrid process of 3D printing and brazing, wherein a body part of a vane of a gas turbine is manufactured using vacuum precision molding during the manufacture of the vane, and a trailing edge part of the vane is stacked and manufactured using 3D printing, thereby bonding the body part of the vane and the trailing edge part using diffusion brazing. As described above, the method for manufacturing a gas turbine vane using a hybrid process of 3D printing and brazing according to the present invention improves the cooling efficiency of the vane to increase the efficiency of power generation and can significantly reduce a defect rate occurring in existing vacuum precision molding, thereby reducing manufacturing costs. 본 발명은 가스터빈 베인제작 방법에 관한 것으로, 더욱 상세하게는 가스터빈의 베인을 제작시 베인의 몸체부는 진공정밀주조를 이용하여 제작하고, 베인의 트레일링 에지(Trailing Edge)부는 3D프린팅으로 적층해서 제작하여 베인의 몸체부와 트레일링 에지(Trailing Edge)부를 확산 브레이징으로 접합하는 것이 특징인 3D프린팅과 브레이징 복합공정을 이용한 가스터빈 베인제작 방법에 관한 것이다. 상술한 바와 같이 본 발명의 3D프린팅과 브레이징 복합공정을 이용한 가스터빈 베인제작 방법은 베인의 냉각효율이 향상되어 발전효율이 증대되고, 또한 종래의 진공정밀주조에서는 발생하는 불량률을 매우 낮출 수 있어 제작단가를 절감할 수 있다는 장점이 있다.
