Embodiment 1

[0023] The three-dimensional printing method of the present embodiment 1, the steps are as follows:

[0024] (1) Use a quantitative rate of 100g / m 2 Coated paper, selected from Toyopin blue ink mixed with ferric oxide particles, the screen line number is 225 lines / inch, the font size is selected as No. 4, and the qualified printing substrate with printed text is completed by letterpress printing. After printing, 0.5 h enters the powder spraying step, and sprays a layer of magnetic fine powder to the printed text. At this time, the magnetic fine powder is naturally attached to the printing ink. The powder spraying operation adopts special powder spraying equipment for automatic powder spraying. The specific operation is to install a 100-mesh filter at the powder spraying port of the powder spraying equipment, set the delivery sample sheet speed to 220 sheets / min, and put the printed substrate on the The paper transfer table is then sent to the powder spraying equipment, the va...

Embodiment 2

[0029] The three-dimensional printing method of the second embodiment, the steps are as follows:

[0030] (1) Prepare the printed substrate:

[0031] Quantitative use is 100g / m 2 Coated paper, using oriental magenta ink mixed with ferric oxide particles, the number of screening lines is 250 lines / inch, the font size is selected as No. 5, and the qualified printing substrate is completed by offset printing. After printing, it enters the powder spraying step 1 hour after printing. The printing substrate obtained in step (1) is placed on the paper transfer table of the powder spraying equipment, and a vacuum blowing device is set to blow air, and a layer of magnetic fine powder is sprayed on the printed characters. At this time, the magnetic fine powder naturally adheres to the ink. In this embodiment The medium magnetic fine powder is made of ferric oxide particles attached to PVC810 fine powder, the particle size is 20 μm, the transfer sample speed is set to 250 sheets / min, th...

Embodiment 3

[0036] The three-dimensional printing method of the second embodiment, the steps are as follows:

[0037] (1) Prepare the printed substrate:

[0038] Use film sheet, screen line number 200 lines / inch, choose black PET screen printing ink mixed with ferric oxide particles, select font size as No. 3, complete through screen printing, obtain qualified printing substrates, enter the powder spraying step 1 hour after printing is completed , select the magnetic fine powder of ferric oxide particles attached to PVC810 fine powder, 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, and set the transfer proof speed to 250 Sheets / min, adjust the size of the fine powder nozzle to 6mm, install a filter screen with a mesh number of 100 at the powder nozzle, and dust the printing substrate with the help of powder spray equipment to obtain a printed powder spray product;

[0039] (2) Turn on ...

Abstract

The invention discloses a three-dimensional printing method. The method comprises the following steps that 1, a printed material which is qualified in printing and in a semi-dry state is taken down from a printing machine, printing ink comprises an ink part and magnetic particles, colored magnetic young powder is sprayed to an inking part, and the powder spraying amount is controlled by controlling the size of a powder spraying opening and the paper feeding speed, so that the young powder adheres to the inking part, and a printed and powder-sprayed product is obtained; 2, the printed and powder-sprayed product obtained in step 1 after young powder spraying is heated and dried to form a three-dimensional high-glossiness satin-like thin film, and a prefabricated product is obtained; 3, the prefabricated product is cooled, and a three-dimensional, highlighting printed product is obtained. According to the method, the young powder is sprayed on the un-dried printed material, and the youngpowder can react with a printing ink connecting material of an image-text part on the printed material at high temperature, so that the image-text thickness is increased, the highlighting effect is formed, three-dimensional printing is achieved in the broad sense, and the efficiency of the three-dimensional printing technology and the aesthetic feeling and quality of the printed product are greatly improved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a three-dimensional printing method. 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. After the stereoscopic grating image s...
