Abstract
Three-dimensional molding equipment alternately repeats a laminating process forming a powder layer by powder supply equipment and a sintering process radiating a beam to the powder layer by a plurality of beam scanning equipment and further moving a radiated location with respective predetermined moving units set by a central control unit to sinter the powder layer, wherein a plurality of the beams by the beam scanning equipment are radiated on the same powder layer, and the radiated locations by the beam scanning equipment are synchronously moved in increments of moving units, the plurality of beam scanning equipment includes at least one beam scanning equipment for a large-diameter region forming at least one large-diameter radiated region on the powder layer surface; and at least one beam scanning equipment for a small-diameter region, forming at least one small-diameter radiated region having a smaller diameter on the powder layer surface.
