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
[0006] In addition, not only that, the stereoscopic image forming method of the above-mentioned Japanese Laid-Open Patent Publication No. 54-089638 or Japanese Laid-Open Patent Publication No. 2001-150812 all is to form an image first and then thermally expand to make the image surface rise, so after the expansion Cracks appear on the surface of the image after
As a result, there is a problem that the image quality of the stereoscopic image is significantly degraded

Embodiment 1

[0074] Figure 4A , Figure 4B and Figure 4C It is a schematic diagram of the basic concept of producing a three-dimensional surface on the thermally expandable sheet 17 in the first embodiment of the three-dimensional printing apparatus 1 having 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 illustrate the processing principle of selectively foaming and partially bulging the heat-expandable sheet 17 . Figure 4C It is a cross-sectional view showing the machining 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 coated on the base material 56 . The base material 56 is made of cloth such as paper or canvas, or panel materials such as plastic, and its material is not particularly limited. As the thermally expandable sheet 17 composed of the substrate...

Embodiment 2

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

[0099] The pure black image 71 and the pure gray image 72 have different heat absorption rates due to differences in black density. Therefore, if the thermally expandable sheet 17 is subjected to heating and foaming treatment, as Figure 6C As shown, the portion L of the pure black image 71 of the foamed resin layer 57 is largely raised due to thermal expansion.

[0100] Furthermore, although the portion N of the pure gray image 72 rises due to thermal expansion, the amount of rise is smaller than that of the por...

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 ...
