SYSTEM FOR MANUFACTURING OF THREE DIMENSIONAL OBJECTS

A system for manufacturing of three dimensional objects by layered deposition is provided. The system includes a base substrate for formation of three dimensional objects placed on a supporting plate; a functional assembly comprising a gas-discharge electron beam gun, a feedstock guide, a cold annular cathode and two annular anode electrodes, a high voltage power supply of the gas-discharge electron beam gun, a system of precise positioning of the supporting plate with the base substrate), a vacuum tight operation chamber, a vacuum subsystem for creating of necessary vacuum inside said operating chamber, a control system and a magnetic lens. The lens is placed on the underside of the gas-discharge electron beam gun coaxially with it and with the feedstock guide, providing the possibility of transformation of a primary hollow electron beam to the shape of a hollow inverted cone after leaving the discharge chamber of the gas-discharge electron beam gun.
