Zusammenfassung:	The present invention relates to a polylactic acid-lignin composite material for 3D printing. In addition, the present invention relates to a manufacturing method of a polylactic acid-lignin composite material for 3D printing. In the present invention, poly(2-ethylhexyl acrylate) (EHA) was grafted onto a lignin surface through a copolymerization method. The poly(2-ethylhexyl acrylate) (EHA) has the same ester group as polylactic acid (PLA) and thus has excellent compatibility with polylactic acid. 본 발명은 3D 프린팅용 폴리젖산-리그닌 복합 재료에 관한 것이다. 또한, 본 발명은 3D 프린팅용 폴리젖산-리그닌 복합 재료의 제조 방법에 관한 것이다. 본 발명에서는 폴리(2-에틸헥실 아크릴레이트)(EHA)를 공중합법을 통해 리그닌 표면에 접목하였다. 폴리(2-에틸헥실 아크릴레이트)(EHA)는 폴리젖산(PLA)과 동일한 에스테르 그룹을 가지고 있으며, 따라서 폴리 젖산과의 호환성이 좋다.
