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

V-CAD data is prepared by dividing external dataconsisting of boundary data of an object into rectangular parallelepiped cellshaving boundary planes orthogonal to each other in accordance with octree division and separating the respective divided cells into internal cellspositioned on the inner side of the object and boundary cellsincluding a boundary face, and a modeling unit quantity of a prototyping materialis changed in accordance with sizes of the internal celland the boundary cellof a modeling portion. The prototyping materialis 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.

Rapid prototyping method and apparatus using V-CAD data

(A) V-CAD data of an object () is prepared. (B) A processed surface shape after NC processing is predicted by simulation using the V-CAD data. (C) The object is subjected to NC processing by a predetermined NC program, and a processed surface shape after NC processing is measured, and (D) processing correction data is obtained from a difference between the processed surface shapes acquired by simulation and measurement, and the NC program is corrected based on the processing correction data. As a result, the ultra-precise processing is enabled even if a workpiece or a tool has low rigidity and an inconstant quantity of deformation.

Ultra-precise processing method and apparatus for inhomogeneous material

There is prepared V-CAD data obtained by dividing external dataconsisting of boundary data of an object into rectangular parallelepiped cellshaving boundary planes orthogonal to each other in accordance with octree division and separating the respective divided cells into internal cellspositioned on the inner side of the object and boundary cellsincluding a boundary face, and mold data and mold processing data used to manufacture the object are generated from data of a reference plane which at least partially comes into contact with the objectand the V-CAD data. Further, in the mold processing data, a plurality of the processing toolsare selected in descending order of a size in accordance with sizes of the internal cellsof a processing portion, and the processing toolis moved in a plane of the mold and in the thickness direction, thereby processing the mold. As a result, by using the V-CAD data, the NC processing program for mold processing can be simplified, and the mold processing time can be greatly reduced.

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 layeris formed. A liquid-phase, photo-curable resin is applied on the upper surface thereof and a colored layercomprising 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) on the upper surface of colored layercan be conducted without obstacles. Colored layerthrough colored layerare formed by repeating this process, a colored layeris formed on the upper surface of colored layer, and then the uppermost layeris formed on the colored layer.
