Zusammenfassung:	The present invention relates to a method for manufacturing a shroud block of a gas turbine and, more specifically, to a method for manufacturing a shroud block of a gas turbine in which a portion having a simplified shape of the shroud block is manufactured by casting, and a portion having a complex shape of the shroud block is manufactured by three-dimensional printing. As described above, since a portion having a simplified shape of the shroud block is manufactured by casting and a portion having a complex shape of the shroud block is manufactured by three-dimensional printing, the method for manufacturing the shroud block of the gas turbine by 3D printing can reduce material and processing costs to enhance productivity, and can manufactured shroud blocks in various shapes according to the usage environment since the shroud block is manufactured by three-dimensional printing. 본 발명은 가스터빈의 슈라우드 블록 제조방법에 관한 것으로, 가스터빈의 슈라우드 블록 제조방법에 있어서, 상기 슈라우드 블록은 슈라우드 블록의 단순화된 형상으로 이루어진 부분은 주조로 제조하고, 복잡한 형상으로 이루어진 부분은 3D프린팅으로 제조하는 것이 특징인 3D프린팅에 의한 가스터빈 슈라우드 블록 제조방법에 관한 것이다. 상술한 바와 같이 본 발명 3D프린팅에 의한 가스터빈 슈라우드 블록 제조방법은 슈라우드 블록의 단순화된 형상으로 이루어진 부분은 주조로 제조하고, 복잡한 형상으로 이루어진 부분은 3D프린팅으로 제조함으로써 소재와 가공비를 절감하여 생산성을 향상시킬 수 있으며, 또한 슈라우드 블록을 3D프린팅으로 제작하기에 사용환경에 따라 슈라우드 블록의 형상을 다양하게 제작할 수 있다는 등의 현저한 효과가 있다.
