Abstract: A three-dimensional shaped object can achieve both of a property in the case of a high dense degree and a property in the case of a low dense degree, and have a high strength. The three-dimensional shaped object includes a dense portion formed on one side so as to be dense, and a porous portion formed on an opposite side so as to be porous. The dense portion and the porous portion are formed by a reaction product of a ceramic material with a chelating agent.

Abstract: An artificial bone forming method, comprising a) a powder layer forming step (32) for forming, into a flat powder layer (6), a powder bone material (5) having biocompatibility and hardening by hydration, b) a partial hardening step (34) for jetting an aqueous solution (7) with biocompatibility to a part of the powder layer to harden a jetted portion (6a) by hydration, and c) an artificial bone forming step (36) for repeating the steps a) and b) for lamination to form a specified artificial bone (9) of a predetermined three-dimensional structure in which the hardened portions (6a) are connected to each other.

Abstract: In coloration of a shaped article composed of a curable resin, the addition operation can be reliably conducted and a reliable coloration effect can be obtained in both the single-color addition and in the multicolor addition. A liquid-phase, non-colored photo-curable resin is cured by irradiation with laser light and a lowermost layer 5n is formed. A liquid-phase, photo-curable resin is applied on the upper surface thereof and a colored layer 5n-1 comprising a cured non-colored region and a liquid-phase pool region is formed. A color ink is drop-wise added to the liquid-phase pool region. The pool region is irradiated with laser light and cured to the same hardness as that of the non-colored region. A block-like coating film having the prescribed thickness if formed from the surface coating film produced by the color ink covering the pool region. As a result, the formation of the next layer (colored layer 5n-2) on the upper surface of colored layer 5n-1 can be conducted without obstacles.

Abstract: There is provided an apparatus for solidifying and shaping fluid which can be optically cured, including (a) an optically scanning device for scanning a level of fluid which can be optically cured, with a light beam, (b) a sinking device for sinking a layer having been cured by scanning carried out by the optically scanning device, below a level of the fluid, and (c) a recoat device for covering a cured layer having been sunk in the step (b), with a fluid which is not yet cured. The recoat device is formed with a recoater blade which horizontally moves above a level of the cured layer with a predetermined gap kept therebetween to smooth a level of the not yet cured fluid. The optically scanning device scans a level of not yet cured fluid having been smoothed by the recoater blade, with a light beam, simultaneously with scanning of the optically scanning device.
