  • Three-dimensional laminating and shaping apparatus, control method of three-dimensional laminating and shaping apparatus, and control program of three-dimensional laminating and shaping apparatus
    Patent number: 10882140
    Abstract: The temperature of a molten pool is measured based on an image captured by an infrared camera or the like. A three-dimensional laminating and shaping apparatus include a material ejector that ejects a material of a three-dimensional laminated and shaped object. The three-dimensional laminating and shaping apparatus includes a light beam irradiator that irradiates the ejected material with a light beam. The three-dimensional laminating and shaping apparatus includes an image capturer that captures a molten pool of the material formed by irradiating the ejected material with the light beam. The three-dimensional laminating and shaping apparatus includes a temperature deriving unit that derives a temperature of the molten pool based on a luminance of an image of the molten pool captured by the image capturer.
