삼차원 구조체 제작 방법 {MANUFACTURING METHOD OF THREE-DIMENSIONAL STRUCTURE}TECHNICAL FIELD [0001] The present invention relates to a method of manufacturing a three-

본 발명은 삼차원 구조체 제작 방법에 관한 것이다.
The present invention relates to a method of manufacturing a three-dimensional structure.

일반적으로 프린터는 입력된 사진이나 문서에 따라 잉크를 분사하는 이차원적인 기술이다. 하지만 요즘은, 차세대 생산 기술 중 하나로 삼차원 프린팅 기술이 주목 받고 있다. 디지털화된 삼차원 제품 디자인의 이차원 단면을 연속적으로 재구성하여 소재를 한 층씩 인쇄하면서 적층하는 방식이다. 그래서 재료를 자르거나 깍는 방식의 전통적인 생산방식은 절삭가공(Subtractive manufacturing)이라 하는 반면, 삼차원 프린팅은 새로운 층을 적층하여 쌓는 방식이기 때문에 적층가공(Additive manufacturing)이라 한다.Generally, a printer is a two-dimensional technique that ejects ink according to an input photograph or document. Nowadays, three-dimensional printing technology is attracting attention as one of the next generation production technologies. A two-dimensional cross-section of a digitized three-dimensional product design is continuously reconstructed to laminate the materials one by one. Therefore, the traditional production method of cutting or cutting materials is called "subtractive manufacturing", while the three-dimensional printing is called "additive manufacturing" because it is a method of stacking new layers.

또한, 삼차원 프린팅은 주로 시제품 제작에 이용되어 왔다. 전통적인 시제품 제작 방식은 여러 단계를 거쳐야 하는 반면, 삼차원 프린팅은 출력을 위한 도면이 준비되어 있으면 그 자리에서 시제품을 제작할 수 있기 때문이다. 그리고, 별도의 금형을 제작하거나 여러 종류에 기기를 사용하여 조립하는 일이 적어 초기 투자 규모 역시 줄일 수 있다.In addition, three-dimensional printing has been mainly used for prototype production. Traditional prototyping methods require several steps, whereas three-dimensional printing can produce prototypes in situ if drawings for output are available. In addition, the initial investment can also be reduced because it is not necessary to manufacture a separate mold or assemble using various kinds of devices.
