3차원 다공성 구조체를 제조하는 방법 및 시스템이 개시된다. 이 방법 및 시스템에서, 상호 연결된 필라멘트는 사전 결정된 배열로 복수의 적층된 층으로 디포짓되고, 연속 층의 필라멘트들은 상호 연결된 기공을 갖는 다공성 구조체를 얻기 위해 서로 연결되고, 층 내의 필라멘트들은 물결 모양 경로를 따라 디포짓되어, 상기 물결 모양 경로를 따라 디포짓된 인접한 필라멘트들의 적어도 하나의 서브세트 사이에 좁은 영역 및 넓은 영역이 형성되고, 복수의 적층된 층들은 연속 층에 형성된 넓은 영역이 적어도 부분적으로 중첩되도록 배치되어 구조-내 채널을 형성한다. A method and system for manufacturing a three-dimensional porous structure, wherein interconnected filaments are deposited in a predetermined arrangement in a plurality of stacked layers, wherein the filaments of the consecutive layers are connected to one another to obtain the porous structure with interconnected pores, wherein filaments in the layers are deposited along waved paths such that narrowed regions and widened regions between at least one subset of adjacent filaments deposited along said waved paths are formed, wherein the plurality of stacked layers are positioned such that the widened regions formed in subsequent layers are at least partially overlapping so as to form intra-structure channels.
