본 발명은, 열가소성 수지 (A)와, 섬유 길이 3~9mm 또한 섬유경 5~20μm인 섬유상 강화재 (B)와, 엘라스토머 (C)를 함유하는 것을 특징으로 하는 섬유 강화 수지 필라멘트 및 조형물을 제공한다. 본 발명의 섬유 강화 수지 필라멘트에 의해, 권취 가능한 3D 프린트용 열가소 수지 필라멘트가 얻어지고, 이를 이용하여 열 용융 적층법에 의한 조형을 행하여 얻어지는 조형물이 적합한 기계 물성을 나타내는 것을 발견하여, 본 발명을 완성하기에 이르렀다. The present invention provides a fiber-reinforced resin filament and an object, the fiber-reinforced resin filament containing a thermoplastic resin (A), a fibrous reinforcing material (B) having a fiber length of 3 to 9 mm and a fiber diameter of 5 to 20 µm, and an elastomer (C). The fiber-reinforced resin filament of the present invention provides a thermoplastic resin filament for 3D printing that can be wound up, and an object built by fused deposition modeling using this fiber-reinforced resin filament exhibits suitable mechanical properties. This finding has led to completion of the present invention.
