The propeller is manufactured using 3D printing:

Traditionally, the propeller is manufactured by molding blanks and subsequent machining.

Engineers first made the propeller for repair viitorului columns of the DRC model 150 laser by direct cultivation on a 3D printer. The screw, manufactured according to additive technology, was able to alleviate by 25 %, thus reducing the load on shaft and bearings, increasing the overall service life of the screw. The production time of printing screw took about 4 days.

In addition, the method of direct laser growing allows you to follow exactly in the manufacture of all the parameters of the propeller radius R (i.e. the distance from the axis of the screw to the end edges) of the step-section, blade pitch, step screw, blade thickness, length of the cross sections of the blade, the distance from the centerline of the blade to the outlet edge, the smoothness and roughness of the surface and a number of other parameters and to produce screws of various steels and alloys.
