Abstract
To obtain a metal additive manufacturing apparatus capable of suppressing a smoke phenomenon without using mechanical impact or external force, thereby preventing contamination and deformation of metal powder.SOLUTION: A metal additive manufacturing apparatus includes: a recoater 50 that is disposed on a path from a powder container to a forming region and has a powder storage part 51 in which metal powder 25 is stored; a power receiving part 57 that is connected to the recoater 50 and receives an electron beam; and a plurality of terminals 56a and 56b that are provided in the powder storage part 51 and allow a current from the power receiving part 57 to flow to the metal powder 25 in the powder storage part 51, wherein an electrical impact is applied to the metal powder 25 in the powder storage part 51.SELECTED DRAWING: Figure 3
