Abstract: 본 발명은, 생소지(green body)(10)의 3-차원 데이터에 기초하여, 한정된 방식으로 배열되는 절삭 요소들과 함께 분말 또는 페이스트-형 재료(41; 61; 81)로 생소지(10)를 적층 제조하기 위한 방법으로서, 생소지(10)는, 적층 방향(16)으로, 적층 방향(16)에 대해 수직인 2-차원 단면 표면 및 적층 방향(16)에 평행한 층 두께로 이루어지는, N(N ≥ 2)개의 연속적인 실린더형 단면 구역(11, 12, 13, 14, 15)으로 분리되는 것인, 생소지(10)를 적층 제조하기 위한 방법에 있어서: 생소지(10)의 단면 구역들(11, 12, 13, 14, 15)이 각각, 분말 또는 페이스트-형 재료로 생성되는 재료 구역들 및 절삭 요소들이 배치되는 시트 구역들로 분할되는 단계; 적층 방향(16)에 대해 수직으로 배치되는 것 상에, 시트 구역 또는 적층 방향(16)으로 연속적인 복수의 시트 구역에 의해 형성되는 적어도 하나의 캐비티가, 적층 방향(16)으로 절삭 요소를 배열하기 위해 요구되는 삽입 높이를 가질 때까지, 단면 구역의 재료 구역들 또는 적층 방향(16)으로 연속적인 복수의 단면 구역(12, 13, 14, 15)의 재료 구역들이, 도포되는 단계; 및 적어도 하나의 절삭 요소가, 절삭 요소들을 배열하기 위해 요구되는 삽입 높이를 갖는 상기 캐비티들 내에, 배치되는 단계를 구비하는 것인, 방법에 관한 것이다.
