본 발명은 쉘 물질(SM) 층으로 코팅된 코어 물질(CM)을 포함하는 하나 이상의 필라멘트, 및 3차원 압출 프린터(3D 프린터)를 사용하는 융합 필라멘트 제조 공정에 의한 3차원 그린 바디의 제조 방법에 관한 것이다. 상기 3차원 압출 프린터는 하나 이상의 노즐 및 하나 이상의 혼합 요소를 포함한다. 또한, 본 발명은 상기 방법에 의해 수득된 3차원 물체 및 압출된 스트랜드에 관한 것이다. The invention relates to a process for producing a three-dimensional green body by a fused filament fabrication process employing at least one filament, which comprises a core material (CM) coated with a layer of a shell material (SM), and a three-dimensional extrusion printer (3D printer). The three-dimensional extrusion printer 0 contains at least one nozzle and at least one mixing element. The invention further relates to three-dimensional objects and an extruded strand obtained by the process.
