Title:
THREE-DIMENSIONAL LAMINATED MOLDING DEVICE AND METHOD FOR CONTROLLING THE TYREE-DIMENSIONAL LAMINATE MOLDING DEVICE
Document Type and Number:
Japanese Patent JP2019007051
Kind Code:
A
Abstract:
To provide a three-dimensional laminate molding device suppressing the generation of a smoke phenomenon and also capable of forming a molding in which heterogeneous elements are not contaminated, and a method for controlling the three-dimensional laminated molding device.SOLUTION: Provided is a three-dimensional laminate molding device comprising: a stage to be fed with a powder material; and an electron beam output unit irradiating an electron beam toward the stage, in which the powder material fed to the stage is irradiated with an electron beam and a prescribed region is melted and solidified to form a molding. The device includes: a potential switching unit of switching the potential of the stage to a ground potential or a positive potential; and a control unit of controlling the potential switching unit in such a manner that the potential of the stage reaches a positive potential before the electron beam is irradiated to the powder material fed to the stage.SELECTED DRAWING: Figure 1
