United Engine Corporation (ODK) has developed solutions that allow reducing the cost of engine parts by optimizing additive manufacturing. This was reported by the Center for Additive Technologies (CAT).
The key change is the transition to domestic heat-resistant alloys without expensive alloying elements. Powders are already mass-produced, which reduces dependence on imports and lowers raw material costs.
Engineers also implemented deformation compensation at the digital model stage, which reduces the volume of mechanical finishing and material consumption.
According to Alexey Mazalov, the general director of the center, the combination of solutions provides a significant economic effect in the short term.
The implemented measures collectively ensure a sustainable reduction in operating costs and form the basis for further scaling of serial additive manufacturing.
Earlier it became known that the turbine blades and compressor of the PD-35 engine were also 3D-printed. Additive technologies are also used for manufacturing nozzles and body parts.
