Three-dimensional molding equipment and method for manufacturing three-dimensional shaped molding object

摘要

Three-dimensional molding equipment configured to alternately repeat a laminating process of forming a powder layer by powder supply equipment and a sintering process of radiating a light beam or an electron beam to the powder layer by a light beam or an electron beam scanning equipment (20) and further moving a radiated location with a respective predetermined moving unit set by a central control unit, namely, a computer related to control of a controller, to sinter the powder layer, wherein a plurality of the light beam or electron beam scanning equipments (20) are provided, and a plurality of the light beams or electron beams by the plurality of light beam or electron beam scanning equipments (20) are radiated on the same powder layer, and further the locations radiated by the plurality of the light beam or electron beam scanning equipments (20) are synchronously moved in increments of the moving unit.
