The Rosatom corporation has completed the manufacturing of two unique additive manufacturing units developed by the Central Research Institute of Technology of Mechanical Engineering (TsNIITMASH). The new 3D printers are designed for printing large-sized products of complex geometry and working with hard-to-weld alloys.
MeltMaster3D-550 is one of the largest in terms of working area (550×450×450 mm) among Russian industrial laser melting systems. The unit is equipped with four laser-optical modules, which significantly increases productivity and accuracy in the manufacture of tooling, instruments, and spare parts for heavy industrial equipment.
The second system, MeltMaster3D-350ВТ, stands out from its counterparts due to the integrated function of heating the building platform up to 800 °C. This technology allows efficient printing of parts from alloys with a high susceptibility to cracking, such as titanium and nickel superalloys, widely used in the aerospace and energy industries.
