Problems solved by technology

[0005] However, in the conventional three-dimensional image forming method shown in Japanese Laid-Open Patent Publication No. 54-089638 or Japanese Laid-Open Patent Publication No. 2001-150812, the production of three-dimensional printing is time-consuming, and the process is many and troublesome. Various problems such as complexity and high cost

Example Embodiment

[0073] [Example 1]

[0074] Figure 4A , Figure 4B with Figure 4C It is a schematic diagram of the basic concept of forming a three-dimensional surface on the thermally expandable sheet 17 in Example 1 of the three-dimensional printing apparatus 1 of the above-mentioned structure. Figure 4A The structure of the thermally expandable sheet 17 used in Example 1 is shown. Figure 4B It is used to explain the processing principle of selectively foaming and partially swelling the thermally expandable sheet 17. Figure 4C It is a cross-sectional view showing the processing result.

[0075] Such as Figure 4A As shown, the thermally expandable sheet 17 is composed of a base material 56 and a foamed resin layer 57 containing a thermal foaming agent applied on the base material 56. The base material 56 is composed of cloth such as paper and canvas, panel material such as plastic, and the like, and its material is not particularly limited. As the thermally expandable sheet 17 composed of t...

Example Embodiment

[0097] [Example 2]

[0098] Figure 6A~Figure 6C It is a diagram showing the basic principle of the processing of the embodiment 2 in the three-dimensional printing apparatus 1. Figure 6A It is a plan view of the thermally expandable sheet 17 with the foamed resin layer 57 facing upward, Figure 6B It is the A-A' cross-sectional view. On the surface of the foamed resin layer 57, the density of black printing is changed, and a solid black image 71 and a solid gray image 72 are printed.

[0099] The pure black image 71 and the pure gray image 72 have different heat absorption rates due to the difference in black density. Therefore, if the heat-expandable sheet 17 is heated and foamed, it is as Figure 6C As shown, the portion L of the pure black image 71 of the foamed resin layer 57 greatly rises due to thermal expansion.

[0100] In addition, although the portion N of the pure gray image 72 is raised due to thermal expansion, the amount of rise is lower than that of the portion L of...

Abstract

Desired designated sections (64a, 64b, 65) are selectively extracted from a color image to be printed, the extracted designated sections (64a, 64b, 65) are converted into a solid black image (66) having a high thermal energy absorbency, and the solid black image (66)is printed on the foaming layer surface of a supplied thermal expansion sheet (17). Next, thermal energy (68) is applied by a halogen lamp (27a) in a thermal expansion processing unit, causing the solid black image section to expand and rise. Furthermore, in an ink jet printer unit (4), a prescribed color that is a background color is printed on the entire foaming layer surface of the thermal expansion sheet including the raised sections. Furthermore, the color image to be printed is printed thereon by an ink jet recording method to obtain color image three-dimensional printed material.

Description

[0001] This application is based on Japanese Patent Application No. 2011-038184 for which it applied on February 24, 2011, and the priority is claimed, The content is taken in here as a reference. technical field [0002] The present invention relates to a three-dimensional printing device, a three-dimensional printing system, and a three-dimensional printing method capable of easily producing a printed matter in which a desired portion of a color image is three-dimensionalized with high quality and low cost. Background technique [0003] Conventionally, three-dimensional printing has been realized by means of braille printing, UV ink-based recoating, physical pressing, and three-dimensional printers. For example, in Japanese Laid-Open Patent Publication No. Sho 54-089638, there is known a three-dimensional image forming method in which a low-boiling-point vaporizing substance is microencapsulated with a thermoplastic resin on a base sheet. A heat-expandable sheet formed by ...
