Abstract
A machine and method for additive manufacturing is offered which can eliminate static electricity of a powdered material without using an inert gas to thereby prevent scattering of the material. The additive manufacturing machine () has a support stage (), a first electron gun (), and a second electron gun (). The first electron gun () melts a given region of the powdered material (M). The second electron gun () illuminates the surface of a given region formed by the powdered material spread tightly on the stage () with an electron beam (L) that is tilted relative to the surface to eliminate static electricity of the powdered material (M).
