Abstract
Three-dimensional manufacturing method and apparatus which easily adjust individually a heating amount per unit area for each of solidified and unsolidified regions is provided. Light source and scanning unit heat with a laser beam a layer formed by a layer forming unit. In a layer forming step, a controlling unit causes the layer forming unit to form a layer of material powder. In a laser heating step, the controlling unit controls the light source and the scanning unit to alternately heat with the laser beam the solidified region obtained by fusing and solidifying the layer and the unsolidified region adjacent to the solidified region, thereby integrally fusing and solidifying the solidified region and the unsolidified region.
