Headline:

Highly efficient additive manufacturing technologies

In the world mechanical engineering, knowledge-intensive processes are being actively initiated, associated with the creation of fundamentally new methods for the design and manufacture of complex-profile vital parts, as well as new methods for processing parts. One of the promising directions in this area is the use of hybrid methods for creating mechanical engineering products that combine additive technologies (LENS technologies (Laser Engineered Net Shaping), DMD technologies (Direct Metal Deposition)) and traditional metalworking technologies.

 Hybrid processing allows the production of high-precision products with:

• unique spatial and complex-profile external and internal geometry without the implementation of labor-intensive procurement operations;
• multi-material coating with special multifunctional properties (heat resistance, corrosion resistance, increased strength and wear resistance, reduced friction coefficient).

Abroad, the developer and supplier of hybrid machine tools is DMG Mori (Germany). This issue has not been resolved in Russia.

The goal of the project is the development of design and technological solutions for the implementation of the technology of additive metal cutting production.
