MOSCOW (Sputnik) — VIAM began working in the 3D-printing area in 2015, when it produced a combustion chamber swirler for the next generation PD-14 turbofan being developed by the Aviadvigatel aeroengine manufacturer.
"The engine is made entirely on the basis of VIAM additive manufacturing using new laser sintering technology and metal powder mixes for heat-resistant and aluminum alloys, which have also been developed by the institute's experts. We were able to print an engine with unique parameters impossible to achieve with conventional casting by using additive manufacture technology. For example, the thickness of the combustion chamber's walls is 0.3 millimeters. Such parameters are only possible with 3D printing," VIAM Director General Evgeny Kablov told the Izvestia newspaper.
VIAM and FPI will continue the 3D printing experiment and develop Russia's additive manufacture sector, according to FPI deputy head Alexander Panfilov.
"After the experiment, we will begin joint work on developing additive technologies in our country to broaden the range of materials as well as developing our own unique 3D printing stations," Panfilov told the newspaper.
