Scientists of the Scientific and Production Association "LUCH" (part of the Scientific Division of Rosatom State Corporation) have developed a prototype of a selective electron beam powder melting (SEBM, 3D printer) unit with high-temperature heating of the working volume. This was reported by the press service of the state corporation.
The unit is designed for additive manufacturing of complex-shaped products from powders of refractory metals (tungsten, molybdenum, niobium) and their compositions.
For example, turbine unit components can be made from these materials. Such products will have high physical and mechanical characteristics and operate at high temperatures.
According to Sergey Pshenov, Head of the Additive Technologies Laboratory of the ISTOK Scientific and Technical Center, the printing process takes place in a vacuum. The technology is suitable for working with metals and alloys so that they do not oxidize under the influence of oxygen.
The manufacturing accuracy of the product is 100 μm. The 3D printer reduces the cost of the part by 20%. The level of equipment localization is 90%.
