Embodiment Construction

[0029] Best way to implement the invention

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0031] figure 2 It is a cross-sectional view showing an example of a colored molded product composed of a photocurable resin according to an embodiment of the present invention.

[0032] The above-mentioned colored molded article is a molded article formed by synthesizing photocurable resin layers, and its overall shape is not limited to a specific shape, and even if it is viewed from above or below, it can be assumed to be a rectangle (square) or a circle. shape, ellipse and other shapes. The above-mentioned colored moldings, such as figure 2 Shown, the top layer 5 1 and bottom level 5 n It is a layer (normal layer) composed of uncolored photocurable resin, and the uppermost layer 5 1 with bottom 5 n The layers laminated between them are respectively layers (colored layers) composed of...

Abstract

The liquid-phase non-colored photocurable resin is irradiated with laser light to be cured to form the lowermost layer 5n. A liquid-phase photocurable resin is coated thereon to form a colored layer 5n-1 composed of a cured non-colored region and a liquid-phase pooled region. Drops of colored ink in the liquid phase of the pool area. Irradiate the pool area with laser light to cure it to the same level of hardness as the non-colored area. A planar coat of colored ink covering the pool area creates a seal coat of set thickness. Therefore, the formation of the next layer (colored layer 5n-2) on the colored layer 5n-1 is not affected. This process is repeated to form the colored layer 5n-2 to the colored layer 53 , the colored layer 52 is formed on the colored layer 53 , and the uppermost layer 51 is formed on the colored layer 52 . With this method, regardless of single-color addition or multi-color addition, the addition operation can be performed accurately and reliable coloring effects can be obtained.

Description

technical field [0001] The present invention relates to a method for producing a colored molded article composed of a curable resin, a colored molded article composed of a curable resin, and a molding device. technical background [0002] The coloring of a molded product made by photoforming, that is, a molded product formed by layering a photocurable resin with laser light irradiation, is affected by the original color (usually translucent color) of the above-mentioned resin itself. Great constraints. Therefore, conventionally, a method of adding a colorant to the resulting molded product after a series of layered moldings has been performed has been employed. [0003] However, in the above-mentioned conventional coloring method, in order to add the colorant to the above-mentioned molded article, a huge facility is required. Moreover, when the coloring object is a molded product with a complex shape, or a molded product with a complex shape simila...
