Problems solved by technology

[0005] The purpose of the present invention is to provide a three-dimensional printing process and three-dimensional printed matter to solve the problems in the prior art that the three-dimensional printing process is complicated, the requirements for personnel and materials are harsh, the cost is high, and the scale is small. The fine powder is sprayed on the printing substrate, and the fine powder can react with the ink binder of the graphic part on the printing substrate at high temperature, thereby increasing the thickness of the graphic and text, forming a prominent effect, and realizing three-dimensional printing in a broad sense, which greatly improves The efficiency of the three-dimensional printing process and the beauty and quality of the printed matter are conducive to enhancing the competitiveness of the company's products and are more suitable for large-scale production

Embodiment 1

[0026] The present embodiment specifies the three-dimensional printing process of the present invention and the product prepared thereof, and the process steps are as follows:

[0027] (1) Use a quantitative rate of 200g / m 2 Coated paper, selected Toyopin blue ink, screen line number is 175 lines / inch, font size is selected as No. 4, through letterpress printing, complete the qualified printing substrate printed with the text of "high-end packaging box", enter the box 1 hour after printing is completed Dusting steps.

[0028] Spray a layer of fine powder on the "high-end" part of the printed text "high-grade packaging box", and at this time the fine powder will naturally adhere to the ink. In this embodiment, the fine powder is PVC810, and the particle size is controlled at 5-6 μm. The powder spraying operation uses The special powder spraying equipment sprays powder automatically. The specific operation is to install a 400-mesh filter at the powder spraying port of the powde...

Embodiment 2

[0033] This embodiment also exemplifies and specifically describes the three-dimensional printing process of the present invention, and the specific steps are as follows:

[0034] (1) Prepare the printed substrate:

[0035] Quantitative use is 157g / m 2 Coated paper, oriental magenta ink is selected, the number of screening lines is 150 lines / inch, and the font size is selected as No. 5. The qualified printing substrate is completed by offset printing, and the powder spraying step is entered 1 hour after printing is completed.

[0036] (2) Spray fine powder

[0037] Select transparent fine powder with a particle size of 5 μm and a temperature resistance of 370°C, place the printing substrate obtained in step (1) on the paper transfer table of the powder spraying equipment, set the vacuum blowing device to blow air, and set the transfer speed of the sample sheet to 100 sheets / min, adjust the size of the fine powder nozzle to 4mm, install a filter screen with a mesh number of ...

Abstract

The invention discloses a three-dimensional printing technology and a three-dimensional printed matter, and belongs to the technical field of three-dimensional printing. According to the technical scheme, the three-dimensional printing technology is characterized by comprising the following steps in sequence that (1) printed materials with printed image-text are took, and the image-text part is sprayed with fine powder in a wet state so that printing powdered products can be obtained; (2) the printing powdered products are dried at 350-550 DEG C for 10-20 min, then the printing powdered products are conducted high temperature curing at 550-650 DEG C for 5-20 min, and prefabricated matters are obtained; and (3) the prefabricated matters are cooled at the room temperature, and the three-dimensional printed matter is obtained. The three-dimensional printing technology and the three-dimensional printed matter have the beneficial effects that required devices are low in investment, simple in method, easy to operate, capable of saving labor force, capable of being not limited by the printing method and completed off-line with a printing press, capable of saving space, low in cost and suitable for large-scale promotion; and the obtained three-dimensional printed matter is good in three-dimensional effect, clear in images, high in added value and good in anti-fake capacity.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a three-dimensional printing process and three-dimensional printed matter. Background technique [0002] With the rapid development of the printing industry and the improvement of people's aesthetic requirements for the outer packaging of objects, it has become the development trend of the industry to develop diversified printing methods to improve the added value such as the beauty of printed products and the uniqueness of logos. As an extension and development of traditional printing technology, three-dimensional printing is widely loved by the printing industry for its advantages of realistic reproduction of objects, rich layers, strong three-dimensional effects, and clear product images. [0003] The current three-dimensional printing is often realized by Braille printing, recoating based on UV ink, physical pressing method and three-dimensional printing. ...
