Beschreibung
Zusammenfassung:	One aspect of the present invention provides a method for manufacturing a 3D printing filament, which comprises the steps of: (a) pulverizing resin waste to obtain recycled resin particles; and (b) melting and kneading a mixture containing the recycled resin particles and thermoplastic resin to obtain a melt, and then extruding the melt to manufacture a 3D printing filament. 본 발명의 일 측면은, (a) 수지제 폐기물을 분쇄하여 재생 수지 입자를 얻는 단계; 및 (b) 상기 재생 수지 입자와 열가소성 수지를 포함하는 혼합물을 용융, 혼련하여 용융물을 얻은 후, 상기 용융물을 압출하여 3D 프린팅 필라멘트를 제조하는 단계;를 포함하는 3D 프린팅 필라멘트의 제조방법을 제공한다.
