2025: Product Announcement
On December 18, 2025, the State Scientific Center of the Russian Federation NPO TsNIITMASH (Engineering Division of Rosatom State Corporation) produced and supplied two industrial 3D printers for additive production of metal parts. The recipient of the equipment was the AEM-Spetsstal metallurgical plant, which is also part of the Rosatom structure.
According to the publication "Atom Media," the installations operate using selective laser fusion (SLM) technology. This method consists in layer-by-layer fusion of metal powder particles with a laser to create a solid product of a particular shape. Additive systems make it possible to produce large-sized parts of complex geometry, as well as work with hard-to-weld alloys that are prone to cracking.
One of the shipped models, MeltMaster3D-550, is equipped with four laser-optical systems and has one of the largest working zones among domestic analogues - 550×450×450 mm. This makes it possible to create large components. The second system, MeltMaster3D-350VT, is a unique Russian development with the ability to heat the working surface to 800 degrees Celsius, which is necessary for printing from the most complex alloys.
General Director of NPO TsNIITMASH Viktor Orlov said that SLM technology allows manufacturing parts that are not available for traditional metalworking. According to him, it speeds up the production of components according to individual requirements. Orlov also noted that the production of light and durable elements, as well as the operational manufacture of spare parts, are of strategic importance in conditions of limited access to imported analogues.
Ilya Kavelashvili, director of the Additive Technologies business direction of the Rosatom Fuel Division, said that more than 30 organizations already use 3D printing in the nuclear industry. He stressed that equipping metallurgical production with its own installations is an important step towards technological independence.[1]
