    Abstract: Provided are a powder bed fusion model having improved model strength and a method of fabricating the same. Applying a laser beam to a layer of a resin powder (8) includes: applying the laser beam with a first energy to a modeling area (ma1) in the first layer of the resin powder from the bottom among n layers of the resin powder, in the modeling area (ma2, ma3, man−2, man−1) in each of the second to (n−1)-th layers of the resin powder, applying the laser beam with the first energy to a projecting portion (PA2, PA3, PAn−1) projecting outward from at least one of the modeling areas in the vertically adjacent layers of the resin powder and to an overlapping portion (OA2, OA3, OAn−1) overlapping the modeling areas in the adjacent layers of the resin powder, lying on the inner side of the projecting portion, and having at least a width equal to the thickness of a layer of the resin powder, and applying the laser beam with a second energy lower than the first energy to a center portion on the inner side of the projecting portion and the overlapping portion; and applying the laser beam with the first energy to the modeling area (man) in the n-th layer of the resin powder.
