The present invention discloses a system and method for manufacturing a propeller by using a three-dimensional printer. The system and method maximize propulsion efficiency by forming fluid guide rails in blade surfaces of the propeller, thereby generating propulsion while the fluid is being discharged to rear portions of the blades after a fluid is flown in front portions of the blades during rotation of blades. The system for manufacturing a ship propeller by using a three-dimensional printer includes: a data generation unit which generates three-dimensional modeling data for the ship propeller; and a propeller formation unit which forms the ship propeller based on the three-dimensional modeling data received from the data generation unit, wherein the three-dimensional modeling data are three-dimensional modeling data for the ship propeller including a hub which is formed in a cylindrical shape such that the hub axially rotates in a state that the hub is connected to a drive shaft, a plurality of blades which are provided to be connected to the hub along an outer circumferential surface of the hub, and a plurality of the fluid guide rails which are provided to be formed in the surface of each of the blades proceeding the fluid from the front portions to the rear portions to guide progress of the fluid. Therefore, according to the present invention, the system can lower production costs by enabling the ship propeller to be manufactured by a simple process, and enables mass production of the ship propeller by reducing time required for performing the process.
프로펠러의 날개의 면에 유체 유도 레일이 형성되어, 회전 시 날개의 전단부로부터 유체가 유입되어 후반부로 배출되면서 추진력을 발생시키되, 추진 효율이 극대화되도록 하는 프로펠러를 3D 프린터를 이용하여 제조하는 시스템 및 방법이 개시된다. 3D 프린터를 이용한 선박용 프로펠러 제조 시스템은 선박용 프로펠러에 대한 3D 모델링 데이터를 생성하는 데이터 생성부; 및 상기 데이터 생성부로부터 수신된 상기 3D 모델링 데이터를 기반으로 하여, 상기 선박용 프로펠러를 생성하는 프로펠러 생성부;를 포함하고, 상기 3D 모델링 데이터는, 구동축과 연결되어 축 회전을 하도록 원통형으로 마련되는 허브와, 상기 허브의 외주면을 따라 연결되도록 마련되는 복수의 날개 및 유체를 전단부에서 후단부로 진행시키는 각각의 날개의 면에 마련되어, 상기 유체의 진행을 유도하는 복수의 유체 유도 레일이 형성되는 선박용 프로펠러에 대한 3D 모델링 데이터이다. 이에 의해, 간단한 공정에 의해 선박용 프로펠러를 제조 가능하여 생산 단가를 낮출 수 있으며, 공정에 소요되는 시간이 단축되어 대량 생산이 가능할 수 있다.
