Zusammenfassung:	Disclosed is a polylactic acid loess composition for a three-dimensional printer filament, capable of increasing mechanical strength and crystallization speed of a resin by adding loess as an eco-friendly nucleating agent of a specific composition, an amorphous resin, and a polyolefin resin having one or more hydrophilic functional groups, and contributing to improvement of the output speed of a three-dimensional printer by additionally providing an anticipated toning effect. The polylactic acid loess composition for a three-dimensional printer filament comprises: (A) 90.0-99.9 wt% of a polylactic acid resin; (B) 0.1-10.0 wt% of loess; (C) 0.1-10.0 wt% of an amorphous resin; and (D) 0.1-5.0 wt% of a polyolefin resin having one or more hydrophilic functional groups. 특정 조성의 친환경 조핵제로 황토, 비결정성 수지 및 1개 이상의 친수성 작용기를 가지는 폴리올레핀 수지의 첨가를 통해 수지의 기계적 강도 및 결정화 속도를 증가시키는 한편, 부가적으로 조색효과를 기대할 수 있어, 3차원 프린터 출력속도 향상에 기여하는 내열성과 기계적 물성이 우수한 3 차원 프린터 필라멘트용 폴리유산 황토 조성물이 개시된다. 본 발명은 (A) 폴리유산 수지 90.0~99.9 중량%; (B) 황토 0.1~10.0 중량%; (C) 비결정성 수지 0.1~10.0중량%; 및 (D) 1개 이상의 친수성 작용기를 가지는 폴리올레핀 수지 0.1~5.0 중량%를 포함하는 3차원 프린터 필라멘트용 폴리유산 황토 조성물을 제공한다.
