The Rostec State Corporation has shown how its Additive Technology Center is engaged in the rapid production of aircraft engine components using 3D printing.
The process of layer-by-layer fusion of the part proceeds as follows. First, a special powder is applied to the working surface, then a laser is used to form a layer of the future product from it. These operations are repeated until the part is completely ready.
The unique 3D printing technology significantly reduces the time for development work, since there is no need to manufacture tooling and there is no need to readjust production. In addition, time is saved on the manufacture of parts. At the same time, products are created without loss of strength characteristics. Thus, 3D printing is not inferior in quality to classical casting.
The domestic 3D printer is manufactured by Laser Systems. It is used in the production of components for PD-8 engines for short-haul SJ-100 aircraft, PD-14 for medium-haul MC-21 liners, TV7-117ST-01 for regional Il-114-300 liners and VK-650V for light helicopters.
In 2024, these 3D printers will begin to be fully integrated into the production cycle for aircraft engine parts. The Additive Technology Center has already announced that it is ready to train operators, technologists and designers in the Moscow region to work with these additive installations.
