    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. Colored layer 5n-2 through colored layer 53 are formed by repeating this process, a colored layer 52 is formed on the upper surface of colored layer 53, and then the uppermost layer 51 is formed on the colored layer 52.

    Abstract: V-CAD data is prepared by dividing external data 12 consisting of boundary data of an object into rectangular parallelepiped cells 13 having boundary planes orthogonal to each other in accordance with octree division and separating the respective divided cells into internal cells 13a positioned on the inner side of the object and boundary cells 13b including a boundary face, and a modeling unit quantity of a prototyping material 7 is changed in accordance with sizes of the internal cell 13a and the boundary cell 13b of a modeling portion. The prototyping material 7 is a resin, lumber powder, a low-fusing-point metal, metal powder, ceramics powder or a mixture of a binder and one of these materials, and its modeling unit quantity is set in such a manner that the modeling unit quantity is smaller than a capacity of a corresponding cell and does not protrude from the boundary plane of the cell. As a result, by using the V-CAD data, a program for rapid prototyping can be simplified, and a model production time can be greatly reduced.

    Abstract: External data (12) consisting of the interface data of an object (1) is divided by octtree dividing into rectangular parallelepiped cells (13) having interface planes crossing perpendicularly, and V-CAD data that classify the divided cells into internal cells (13a) located inside the object and interface cells (13b) including interface surfaces is prepared, and die data and die machining data for producing the object (1) are generated from data on reference surfaces at least partially contacting the object (1)and the V-CAD data. Die machining data is used to select a plurality of machining tools (2) in the order of decreasing size according to the sizes of internal cells (13a) in a machining unit to move the machining tools (2) within the planes and the thickness directions of the die to thereby machine the die. Therefore, V-CAD data used can simplify a die-machining NC machining program and significantly reduce a die machining time.

    Abstract: In forming a colored shaped article from a curable resin, the addition of either a single colorant or two or more colorants can be conducted without fail to produce a coloring effect without fail. A liquid, colorless, photocurable resin is irradiated with a laser light and cured to form a lowermost layer 5n. A liquid photocurable resin is applied to the upper side thereof to form a colored layer 5n-1 composed of a cured colorless region and a liquid pond region. A color ink is dropped to the liquid pond region. The liquid pond region is irradiated with a laser light to cure it to the same degree as the colorless region. A block-form coating film having a given thickness is formed from a sheet-form coating film of the color ink with which the pond region is covered. Due to the constitution, formation of the subsequent layer (colored layer 5n-2) on the colored layer 5n-1 can be conducted without any trouble. This process is repeated to form a colored layer 5n-2 to a colored layer 53 and to form a colored layer 52 on the colored layer 53. Furthermore, an uppermost layer 51 is formed on the colored layer 52.
