New technology called xBeam 3D Metal Printing was developed by PJSC SPA «Chervona Hvilya» to solve the most important engineering and economic problems of the currently available methods of additive manufacturing. It is based on application of shaped electron beam as the heat source and of wire as consumable material. The key element of the new engineering solution is a special low-voltage gas-discharge electron gun, with a guide built-in along its axis for consumable wire feeding. A unique hollow conical electron beam generated by such a gun, creates exceptional physical conditions for melting of consumable and its layer-by-layer deposition that not only provides the capabilities of precisely controlled and repeatable manufacturing of products, but also opens up the possibilities for development of new technologies and materials. At present xBeam 3D Metal Printing technology has successfully passed laboratory and practical trials in an experimental 3D-printer. 16 Ref., 13 Figures.
