Ruselectronics Electron beam 3D-printer

2019: Development of the electron beam 3D-printer

On April 8, 2019 the Rostec company reported that Ruselectronics develops the first Russian electron beam 3D-printer for printing metal powders. The equipment will allow to make heavy-duty products for the aerospace industry, medicine, jewelry production, art, sport and automotive industry. The first full-function sample will be made at the end of 2020.

According to the company, main advantages of the electron beam printer for printing metal powders developed by NPP Tory are the high speed and accuracy of work and also low sensitivity to quality of powders. Besides, for operation of the printer it is not required to create the protective atmosphere in the working chamber and an external high-temperature system of heating. In the system of movement of an electron ray there are no mechanical parts that leads to fall forward and accuracy of work.

The technology of printing by method of electron beam melting of metal powders allows to make parts practically of any complexity, including a product of 0.2-0.4 mm in size. 3D - printing of products with bionic design in certain cases allows to reduce weight by 86% that cannot achieve, using traditional manufacturing techniques. The developed 3D-printer consumes less energy and reduces the number of waste to a minimum. Similar machines will allow to create for high-tech industries of a product which will be easier, stronger and more ergonomic. Dmitry Trofimov, CEO of NPP Tory

The electron beam 3D-printer will allow to release parts of jet engines of rockets and a blade of turbines of engines of airplanes, individual medical implants, jewelry of irregular shape, the facilitated elements of architectural constructions and also metalporous thermocathodes for the enterprises of a vacuum very high frequency there are industries.

At printing of a product there is a local melting of powder to the subsequent fast curing. The big capacities reached thanks to the accelerated electron ray allow to execute complete melting even of such refractory metals as tungsten and molybdenum. The parts received after complete local melting of powder differ in density comparable with technology of casting, and high quality of a surface. Additional transactions of agglomeration and post-processing at such technology are not required.
