It may be set to the outer peripheral position of the rear end 312b of the wing.

In this case, the distance between successive points located at the front end 312a of the wing is positioned to be narrower than the distance between successive points located at the rear end 312b of the wing, and the first point P1 is located at the second point ( P2), the third point P3 is the fourth point P4, the fifth point P5 is the sixth point P6, and the seventh point P7 is the eighth point P8 and the line. The connected lines may be connected to have a predetermined curvature, after which the first point P1, the second point P2, the third point P3, and the fourth point P4 are four vertices. And the fifth point P5, the sixth point P6, the seventh point P7, and the eighth point P8 form four vertices in the outward direction from the plane of the wing 312. By protruding a predetermined length to form a thick, the data generating unit 200 may be reproduced with the 3D modeling data to form two fluid guide rails 313 on the surface of each wing 312.

If three fluid guide rails 313 are formed, six fluid guide rails 313 may be formed by setting six points at the front end and the rear end, respectively.

7 is a diagram illustrating a data generator 200 according to another embodiment of the present invention.

If it is determined that the plurality of fluid guide rails 313 are not formed in the propeller 310 included in the generated 3D modeling data, the data generator 200 according to another embodiment may include the plurality of fluid guide rails 313. In front of each wing 312 of the propeller, which is not formed, a respective fluid guide rail 313 formed along the circumference of the concentric circle with respect to the center of rotation P0 of the propeller is provided from the center P0. The 3D modeling data may be regenerated by being formed at the predetermined distances r1 and r2.

As shown in FIG. 7, a plurality of concentric circles are formed based on the center P0 of the propeller on which the plurality of fluid guide rails 313 are not formed, but the radius of the circle is a predetermined value r1 and r2. Each fluid induction rail 313 is formed along the circumference of the concentric circle to have a fluid guide rail that becomes thicker from the front end 312a of each wing to the rear end 312b of each wing ( 313 may be formed to regenerate the 3D modeling data.

Specifically, as shown in FIG. 7, the data generation unit 200 is based on the radius of the concentric circle C4 having the radius of the distance to the end of the wing 312 as a reference to the center of the propeller 310. Each fluid is formed by protruding a predetermined length outwardly from the surface of each wing 312 along a concentric circle C2 having a radius r1 of 0.6 times and a concentric circle C3 having a radius r2 of 0.8 times.

If the generated 3D modeling data is 3D modeling data for the propeller in which the plurality of fluid guide rails are not formed, regenerate 3D modeling data for the propeller in which the plurality of fluid guide rails are formed, Send the regenerated 3D modeling data to the propeller generation unit,
The transmitting of the collected scan data to a data generator may include:
When the generated 3D modeling data is 3D modeling data for a propeller on which the plurality of fluid guide rails are not formed, four points are set at the outer circumference of the front end of each wing, and the rear end of each wing is set. By setting four points on the outer periphery so that the plurality of fluid guide rail is formed,
When the distance from the center of the outer periphery that is farthest away from the center P0 of the propeller on which the plurality of fluid guide rails are not formed is 1, the first point P1 is the center P0. To the outer circumferential position of the front end of the wing 0.65 from, the second point P2 to the outer circumferential position of the rear end of the wing 4 apart from the zoom center point, and the third point P3 is 0.7 from the center P0 At the outer circumferential position of the front end of the wing, the fourth point P4 is set to the outer circumferential position of the rear end of the wing, which is 5 away from the center P0, and the fifth point P5 is 8.5 away from the center P0. The outer circumferential position of the front end of the wing, the sixth point P6 is the outer circumferential position of the rear end of the wing, separated from the center P0 by seven, and the seventh point P7 is the nine The outer peripheral position of the front end portion, the eighth point (P8) is separated by 8 from the center (P0) Outer wings and the rear end of the binary set to the peripheral position,
The distance between successive points located at the front end of the wing is set to be smaller than the distance between successive points located at the rear end of the wing, and the first point P1 is the second point P2 and the third point P3. ) Is connected to the fourth point P4, the fifth point P5 is connected to the sixth point P6, and the seventh point P7 is connected to the eighth point P8 by a line. To have a curvature of,
The first point P1, the second point P2, the third point P3, and the fourth point P4 form four vertices, the fifth point P5, the sixth point P6, The seventh point P7 and the eighth point P8 are formed at four vertices so as to protrude from the surface of each wing in a predetermined length in an outward direction, so that each of the two surfaces of each wing is two Ship propeller manufacturing method using a 3D printer characterized in that the fluid guide rail is formed.
