Estimating the term…
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.
A colored shaped article composed of a curable resin, which comprises a plurality of layers formed by lamination and shaping of the curable resin,
A process for producing colored shaped article from curable resin, said colored shaped article comprising a plurality of layers formed by lamination and shaping of a curable resin, wherein at least one layer of said plurality of layers has a non-colored region where no colorant is added and a colored region formed by adding a colorant, said process comprising the steps of:
A process for producing colored shaped article comprising a plurality of layers formed by lamination and shaping of a curable resin, wherein at least one layer of said plurality of layers has a colored region formed by adding a colorant, this process comprising the steps of:
A shaping apparatus for forming a desired shaped article by lamination and shaping of a liquid-phase, curable resin, this apparatus comprising an addition mechanism that can be displaced in at least the horizontal direction to add a liquid-phase or powdered colorant to said liquid-phase, curable resin.
