en.Wedoany.com Reported - Scientists at the Russian National Research University of Technology have proposed a new method for manufacturing metal molds used in powder metallurgy, eliminating the need for welding and expensive 3D printing, opening up new possibilities for producing parts with complex geometric shapes.

This development is based on cold spray technology, a method in which metal powder is sprayed onto a surface at high speed to form a dense coating. Using this method, thick metal layers can be produced without generating significant internal stress, making it applicable in the aerospace, energy, and mechanical engineering sectors.

Maxim Khomutov, Candidate of Technical Sciences and Senior Researcher at the University's Hybrid Additive Technology Laboratory, noted: "We have demonstrated the possibility of manufacturing complex-shaped shells without welding and expensive printing. In the future, this technology can be used not only for powders but also in additive manufacturing, for example, to compact parts obtained through cold spray technology, paving a new path for manufacturing strong metal products with complex shapes."

The Russian National Research University of Technology has been actively participating in industry exhibitions, attending the "Metal-Expo" exhibition every year. It is reported that the university will also participate in the international specialized exhibition "Metallurgy·Foundry Machinery" to be held from May 26 to 28, 2026, at the Timiryazev Center in Moscow.
