Method of manufacturing a stereoscopic signboard using 3D printing

The present invention relates to a method for manufacturing a three-dimensional signboard using 3D printing, and more particularly, to form a three-dimensional shape with a 3D printer using an embossed modeling file, thereby reducing the cost of manufacturing a separate mold. It relates to a three-dimensional signboard manufacturing method using 3D printing while being able to shorten the production time.

In general, a sign is a sign made by using a name, a brand name, or a business item in order to attract the attention of several people in a store, a company, or an institution. Nowadays, advertising boards, advertising towers, neon signs, or power pole ads are now very diverse.

The history of the signage seems to have been used since ancient Egypt, Greece, and the Roman era. In England, the branches of pine trees or bunches of green leaves were tied to pubs and inns until the 17th century.

Early signboards were displayed as tools used for merchandise and trade, with scissors hanging at tailor shops and hats at hat shops. The emblem of the aristocracy and the name of the merchant's name also appeared, and the 16th-17th century artistic works appeared, and the signboard became popular.

As signs grew and streets became more frequent, the king warned of this in France. In the 18th century, legislation was enacted to remove street signboards and adhere to walls.

In the East, the Chinese signage developed rapidly during the Song Dynasty. There were two Chinese signboards: Zhao Pie, who wrote letters on the board, and Wang Zhi, who placed goods representing the shape and business of the goods.

Since ancient times, the famous pub Wang Zi, and I walked there. There is still an old-fashioned tavern, and you can see signboards such as a boutique and drugstore on the Qing Ming Shang-do.

The signboard of Korea was also similar to that of China in the early days, and was marked with the sign of the robe, which was a kind of jujube, and hung a lantern at the end of the mourning and put a 'ju' character on it.

The Goryeo-do Gyeong Sik-jo has a sum of money at each visit between the two islands, including Yeongtong, Gwangtong, Heungseon, and Trade. It is said that there was a signboard from the Goryeo Dynasty.

Signboards became widespread in the 1920s and led to the regulation of advertisements. Neon signs appeared in the 1960s, and the completion of the Gyeongin Expressway in 1969 coincided with the era of outdoor advertising and billboards. Recent developments in industry and civilization are making the types and forms of signs more diverse.

Such a conventional signboard is produced in various colors, in which case the illumination of the interior is transmitted through the signboard so as to represent a character or figure in various colors formed of the signboard.

However, when the signboard is formed in various colors, by painting on the back of the signboard material plate or cutting and attaching letters or figures on the front surface, the transmittance of light is not constant so that the use of the signboard is deteriorated. There was even the problem of losing the image.

In addition, since the light must pass through the main plate of the character or figure in duplicate, there is a problem that the character or color is not clear and is not easily expressed at night.

In addition, in the case of embossing a character or a figure in order to enhance the ability of the character or figure to be more distinguished, the character or figure of a desired color is formed on the front end of the side wall formed by the shape of the character or figure in which sidewalls protruding uniformly on the surface of the main board member are formed. Since the color is cut out and attached to the finish, this also reduces the vividness of the color as well as a lot of manufacturing labor and has a difficult problem.

On the other hand, in order to promote and promote the company's name or product, there are many advertisement signs installed with various logos, images, and various characters inside and outside the building.

In addition, the installation of a three-dimensional signboard to facilitate the identification of the location and direction, and to guide the public in the public buildings, such as shopping malls, theaters, terminals, subway stations, parks, etc. are gradually spreading.

Such signboards are mainly sheared in the shape of various letters and patterns on a metal plate made of stainless material, and a resin plate such as an acrylic material is adhered to the bottom thereof, and an illumination means such as an LED or a light guide panel is provided therein. Various types of company names and logos on the surface, or patterns such as guiding positions and directions are emitted to make it easier to identify the general public at night.

However, the above-described conventional signboards are manufactured without considering the location or environment in which the signboards inside and outside the building are installed, and thus, the signboards are installed uniformly and have a problem of lowering the advertisement or propaganda effect, which is a function of the signboards. .

Korean Patent Publication No. 10-1045316, Name of invention 'Guide Signage and Manufacturing Method' (Registration date 2011.06.23.)

A) Image selection step (S110)

The image selection step (S110) is a step of selecting an image to be applied to a signboard as shown in FIG. 3, selecting and designing a three-dimensional image of various colors for maximizing advertisement or promotion.

For example, if the signboard is to be used in a shop that sells fish, design the image of a fish that can be easily seen.

B) Relief step (S120a)

As shown in FIG. 4, the relief step S120a is to generate a file by implementing a shape on a plane as a three-dimensional graphic screen, and stereoscopically and retouch the image selected in the image selection step S110. ) Step.

When the ink is poured into it by a squeegee called a squeegee, the ink moves through the mesh in the non-valve area and is printed on a piece of paper or other printed material under the plate. This printing method is called screen printing, and it is possible to print not only flat printed materials but also curved surfaces such as cylinders and cones such as bottles and cups. In particular, screen printing is characterized by clear printing and strong external contamination.
