It relates to a three-dimensional signboard manufacturing method using a 3D printer.

일반적으로 간판은 각종 건물의 내, 외벽면 등에 설치하여 해당 업체의 사업행위나 제품명을 문자, 도형, 기호 등을 통하여 널리 광고하기 위한 것이며, 시각적인 효과를 높이기 위하여 다양한 형태를 갖는다.In general, signboards are installed on the inside and outside walls of various buildings to widely advertise the business activities or product names of the corresponding companies through letters, figures, symbols, etc., and have various forms to enhance the visual effect.

이러한 간판은 평면 프레임의 전면 표면에 각종 문자, 도형, 기호 등으로 이루어지는 광고 내용을 인쇄하는 방식으로 형성되는 평면 간판과 프레임의 표면 또는 벽면에 문자 또는 도형과 같은 광고 내용을 소정 높이만큼 입체형상으로 돌출되게 설치하는 입체간판이 있다.Such a signboard is a flat signboard formed by printing advertisement contents consisting of various characters, figures, symbols, etc. on the front surface of the flat frame, and advertising contents such as letters or figures on the surface or wall of the frame in a three-dimensional shape by a predetermined height. There is a three-dimensional signboard that is installed to protrude.

대한민국 등록특허공보 제10-1965342호(2019.04.03.)에는 외관을 깔끔하고 미려하게 제작할 수 있는 입체간판의 제작방법이 개시되어 있다. 도 1은 종래의 입체간판의 사시도이고, 도 2는 종래의 입체간판의 단면도이다.Republic of Korea Patent Publication No. 10-1965342 (2019.04.03.) discloses a manufacturing method of a three-dimensional signboard that can produce a neat and beautiful appearance. Figure 1 is a perspective view of a conventional three-dimensional signboard, Figure 2 is a cross-sectional view of a conventional three-dimensional signboard.

종래의 입체간판의 정면에는 광확산수지층(500)이 형성된다. 광확산수지층(500)은 엘이디 광원에서 발생하여 외부로 방출되는 빛을 확산시킴으로써 간판을 미려하게 표현할 수 있다. 이러한 광확산수지층(500)을 형성하기 위하여 측면부(100)의 내부에 투광판(300)을 설치하고, 투광판(300)의 상부에 광확산수지를 도포하여 광확산수지층(500)을 형성하였다.A light diffusion resin layer 500 is formed on the front surface of the conventional three-dimensional signboard. The light-diffusion resin layer 500 can express the signboard beautifully by diffusing the light emitted from the LED light source to the outside. In order to form the light-diffusion resin layer 500, a light-transmitting plate 300 is installed inside the side part 100, and a light-diffusion resin is applied to the upper part of the light-diffusing plate 300 to form the light-diffusion resin layer 500. formed.

그러나 광확산수지를 도포할 때 광확산수지를 측면부(100)의 상단 높이에 맞춰 평평하게 채워넣는 것은 매우 어려운 작업이다. 측면부(100)가 비틀려 있을 경우 광확산수지를 수평을 맞춰 평평하게 채워넣기 어렵고, 광확산수지가 넘쳐흐를 경우 측면부(100)를 오염시키게 된다.However, when applying the light-diffusion resin, it is a very difficult task to fill the light-diffusion resin flat to match the top height of the side part 100 . When the side part 100 is twisted, it is difficult to fill the light diffusion resin horizontally and flatly, and when the light diffusion resin overflows, the side part 100 is contaminated.

한편, 측면부(100)의 형상에 맞춰 광확산판을 제작하여 측면부(100)에 결합시키는 방법도 있지만, 광확산판의 형상이 측면부(100) 내부에 꼭 맞도록 정밀하게 제작하기 어렵고, 별도의 결합수단이 필요하다.On the other hand, there is a method of manufacturing the light diffusion plate according to the shape of the side part 100 and coupling it to the side part 100, but it is difficult to precisely manufacture the shape of the light diffusion plate to fit the inside of the side part 100. A bonding means is required.

본 발명은 전술한 문제점을 해결하기 위한 것으로서, 3차원 프린터를 이용하여 작업판위에 필름을 부착하고 필름의 상부에 필라멘트를 적층하여 측면부를 성형하고 이후 필름에 측면부가 부착된 상태에서 광확산수지를 주입함으로써 광확산수지의 주입 및 광확산수지층의 형성이 매우 용이한 3차원 프린터를 이용한 입체간판 제작방법을 제공하는데 그 목적이 있다.The present invention is to solve the above problems, attaching a film on a work plate using a three-dimensional printer, laminating a filament on the top of the film to shape the side part, and then forming a light diffusion resin with the side part attached to the film. An object of the present invention is to provide a method for manufacturing a three-dimensional signboard using a three-dimensional printer, in which injection of a light-diffusion resin and formation of a light-diffusion resin layer are very easy.

상기 목적을 달성하기 위하여 본 발명의 3차원 입체간판 제작방법은, In order to achieve the above object, the method of manufacturing a three-dimensional three-dimensional signboard of the present invention,

작업판에 상단면에는 필라멘트의 안착력 증가를 위해 잉크흡수코팅층이 있고 하단에는 작업판에 부착되는 점착제층이 있는 열가소성수지 재질의 필름을 배치하는 단계;disposing a film made of a thermoplastic resin having an ink-absorbing coating layer on the upper surface of the working plate to increase the anchoring force of the filament and an adhesive layer attached to the working plate on the lower part;

3차원 프린터로 상기 필름의 상부에 필라멘트를 적층하여 입체간판의 측면부를 성형하는 단계;forming a side part of a three-dimensional signboard by laminating a filament on the film with a three-dimensional printer;

상기 필름에 부착되어 형성된 상기 측면부의 내부 및 상기 필름의 상면에 광확산수지를 주입하는 단계;injecting a light-diffusion resin into the inner side of the side portion formed by being attached to the film and the upper surface of the film;

상기 광확산수지가 경화되며 측면부와 접착되고, 상기 광확산수지가 경화되며 상기 필름과 접착되어지는 단계;curing the light-diffusion resin and adhering to the side portion, curing the light-diffusion resin and adhering to the film;

상기 광확산수지가 경화되어 상기 광확산수지층이 일체로 형성된 상기 측면부 및 상기 필름을 상기 작업판으로부터 분리하는 단계;separating the side part and the film integrally formed with the light-diffusion resin layer by curing the light-diffusion resin from the working plate;

상기 광확산수지층과 접착된 상기 필름의 하단면에 열풍기를 이용해 100~200℃의 열을 가하여 상기 광확산수지층과 접착 결합력을 상실시키고, 상기 필름의 유연성을 증가시켜, 상기 필름을 상기 광확산수지층 및 상기 측면부로부터 분리시키는 단계; 및 상기 측면부의 내부에 발광부를 설치하는 단계를 포함한다.By applying heat of 100 to 200 ° C using a hot air blower to the lower surface of the film adhered to the light diffusion resin layer, the light diffusion resin layer and the adhesive bond strength are lost, and the flexibility of the film is increased, and the film is heated to the light. Separating the diffusion resin layer and the side portion; and installing a light emitting part inside the side part.

그리고 상기 측면부 성형 단계에서 상기 측면부는 상기 필름에 입체간판의 형상을 반전시켜 성형하고, 상기 광확산수지층은 상기 측면부의 일측을 차단하여 입체간판의 정면이 된다.And in the step of forming the side part, the side part is molded by inverting the shape of the three-dimensional sign on the film, and the light-diffusion resin layer blocks one side of the side part to become the front side of the three-dimensional signboard.

그리고 상기 작업판은 상기 측면부를 성형한 후 또는 상기 측면부의 내부에 광확산수지를 주입한 후 상기 3차원 프린터로부터 분리되고, 상기 광확산수지가 경화되는 동안 다른 하나의 작업판을 상기 3차원 프린터에 배치하여 새로운 측면부를 형성한다.And the working plate is separated from the 3D printer after molding the side part or after injecting the light-diffusion resin into the inside of the side part, and while the light-diffusion resin is cured, the other working plate is applied to the 3D printer to form a new side part.

그리고 상기 발광부 설치 단계는 엘이디가 장착된 결합판을 상기 측면부의 후방 또는 측면부의 내부에 결합시킨다.And the light emitting unit installation step combines the LED-mounted coupling plate to the rear of the side part or the inside of the side part.

본 발명에 의하면, 상기 필름 코팅면의 질감은 광확산수지층의 표면에 전사된다.According to the present invention, the texture of the film coating surface is transferred to the surface of the light diffusion resin layer.

본 발명의 3차원 프린터를 이용한 입체간판 제작방법은 입체간판의 제작이 용이하고, 3차원 프린터를 이용하여 측면부를 작업판에 형성한 후 작업판에 측면부가 부착된 상태에서 광확산수지를 주입함으로써 광확산수지의 주입 및 광확산수지층의 형성이 매우 용이하다.The three-dimensional signboard manufacturing method using a three-dimensional printer of the present invention is easy to produce a three-dimensional signboard, and after forming the side part on the working plate using a three-dimensional printer, by injecting the light diffusion resin in the state that the side part is attached to the working plate. It is very easy to inject the light-diffusion resin and form the light-diffusion resin layer.

구체적으로 작업판에 부착되어 있는 측면부의 내부 공간으로 광확산수지를 주입함으로써 측면부의 하단과 광확산수지층의 표면의 위치가 일치하도록 형성할 수 있고, 입체간판의 정면으로 노출되는 광확산수지층의 표면을 평평하고 반듯하게 형성할 수 있다. 이에 따라 광학산수지를 측면부의 내부 공간으로 주입할 때 측면부의 뒤틀림을 바로잡거나 광확산수지가 넘쳐 흐르지 않도록 주의할 필요가 없다.Specifically, by injecting the light-diffusion resin into the inner space of the side part attached to the work plate, the position of the lower end of the side part and the surface of the light-diffusion resin layer can be formed to match, and the light-diffusion resin layer exposed to the front of the three-dimensional signboard The surface of the can be formed flat and even. Accordingly, when injecting the optical acid resin into the inner space of the side part, there is no need to correct the distortion of the side part or take care not to overflow the optical diffusion resin.

본 발명의 실시예에 따른 3차원 프린터를 이용한 입체간판 제작방법은 도 3 내지 도 8에 도시된 바와 같이, 측면부(100), 광확산수지층(500), 엘이디(L) 및 결합판(600)으로 구성되는 입체간판 중 측면부(100)를 3차원 프린터(P)로 성형한 후 나머지 구성들을 측면부(100)와 결합시켜 완성한다. 이하, 본 발명의 3차원 프린터를 이용한 입체간판 제작방법에 대하여 구체적으로 설명한다.A three-dimensional signage manufacturing method using a three-dimensional printer according to an embodiment of the present invention is, as shown in FIGS. 3 to 8, a side part 100, a light diffusion resin layer 500, an LED (L) and a coupling plate 600 ) of the three-dimensional signboard consisting of a side part 100 is molded with a three-dimensional printer (P), and then the remaining components are combined with the side part 100 to complete it. Hereinafter, a three-dimensional signboard manufacturing method using the three-dimensional printer of the present invention will be described in detail.

먼저, 도 5에 도시된 바와 같이, 작업판(A)에 필름(F)을 배치한다.First, as shown in Figure 5, the film (F) is placed on the working plate (A).

그리고, 3차원 프린터(P)로 필름(F)의 상면에 필라멘트를 적층하여 입체간판의 측면부(100)를 성형한다. 3차원 프린터로 측면부(100)를 성형할 때는 도 4에 도시된 바와 같이 간판의 형상을 좌우 반전시켜 성형한다. 3차원 프린터(P)에 의해 성형되는 측면부(100)는 하부가 입체간판의 정면이 되고, 상부가 입체간판의 배면이 되기 때문에 측면부(100)를 성형하기 위하여 3차원 프린터(P)를 설정할 때 간판의 형상을 좌우 반전시켜야 한다. 즉 3차원 프린터(P)에 의해 성형된 측면부(100)는 입체간판으로 사용시에 뒤집어 사용하게 된다.Then, by laminating a filament on the upper surface of the film (F) with a three-dimensional printer (P) to mold the side part 100 of the three-dimensional signboard. When molding the side part 100 with a 3D printer, as shown in FIG. 4 , the shape of the sign is reversed left and right to form. When setting the 3D printer (P) to mold the side part 100 because the lower part becomes the front side of the three-dimensional signboard, and the upper part becomes the back surface of the three-dimensional signboard, the side part 100 being molded by the three-dimensional printer (P) The shape of the sign should be reversed left and right. That is, the side part 100 molded by the three-dimensional printer (P) is turned over when used as a three-dimensional signboard.

필름(F)은 열을 가하면 유연성이 증가하는 열가소성 합성수지 재질로, 상단면에는 필라멘트의 안착력 증가를 위해 잉크흡수코팅층이 있고, 하단면에는 작업판에 부착되는 점착제층이 있다.The film (F) is made of a thermoplastic synthetic resin material that increases flexibility when heat is applied. The upper surface has an ink-absorbing coating layer to increase the anchoring force of the filament, and the lower surface has an adhesive layer attached to the working plate.

예를 들면, 실사출력용 PVC 필름은 열가소성 합성수지 재질로 잉크흡수층이 상부면에 코팅되어 있어 상기 필름(F)으로 사용하기 적합하며, 일반적으로 사용되기에 가격도 저렴하다.For example, the PVC film for actual printing is made of a thermoplastic synthetic resin material and the ink absorption layer is coated on the upper surface, so it is suitable for use as the film (F), and the price is low because it is generally used.

광학산수지 주입 단계는 도 7에 도시된 바와 같이 측면부(100)가 필름(F)에 부착된 상태에서 측면부(100)의 내부 공간으로 광확산수지를 주입한다. 전술한 바와 같이 측면부(100)는 필름(F)에 밀착된 상태로 부착되어 있기 때문에 측면부(100)의 내부 공간에 광확산수지를 주입하여 채워 넣을 수 있다. 광확산수지는 경화되어 광확산수지층(500)이 되므로 설계된 광확산수지층(500)의 두께만큼 광확산수지를 주입한다. 이와 같이 필름(F)에 부착되어 있는 측면부(100)의 내부 공간으로 광확산수지를 주입함으로써 측면부(100)의 하단(실제 입체간판에서는 전방)과 광확산수지층(500)의 표면 위치가 일치하도록 평평하게 형성될 수 있다. 따라서 본 발명은 측면부(100)의 뒤틀림을 바로잡거나 광확산수지가 넘쳐 흐르지 않도록 주의할 필요가 없다.In the optical acid resin injection step, as shown in FIG. 7 , the light diffusion resin is injected into the inner space of the side part 100 while the side part 100 is attached to the film F. As described above, since the side part 100 is attached in close contact with the film F, the light diffusion resin may be injected into the inner space of the side part 100 to be filled. Since the light-diffusion resin is cured to become the light-diffusion resin layer 500 , the light-diffusion resin is injected as much as the thickness of the designed light-diffusion resin layer 500 . In this way, by injecting the light diffusion resin into the inner space of the side portion 100 attached to the film F, the lower end of the side portion 100 (the front in the actual three-dimensional signboard) and the surface position of the light diffusion resin layer 500 match It can be formed flat to do so. Therefore, in the present invention, there is no need to correct the distortion of the side part 100 or take care not to overflow the light diffusion resin.

또한, 측면부(100)의 성형단계에서 광확산수지층의 두께를 표시하는 표시돌기부(도면 없음)를 형성하여, 광확산수지 주입량을 조절할 수 있다.In addition, by forming a display protrusion (not shown) indicating the thickness of the light-diffusion resin layer in the forming step of the side portion 100, the amount of light-diffusion resin injected can be adjusted.

또한, 광확산수지를 표시돌기부 보다 높게 주입하면, 광확산수지층과 측면부의 접합 결합력을 높일 수 있다.In addition, if the light-diffusion resin is injected higher than the display protrusion, the bonding strength between the light-diffusion resin layer and the side surface can be increased.

측면부(100)의 내부 공간에 광확산수지의 주입이 완료되면 3차원 프린터 장치로부터 작업판(A)을 분리할 수 있다. 작업판(A)은 여러개가 준비될 수 있으며 3차원 프린터(P) 장치에 탈착가능하게 장착된다. 이에 따라 광확산수지의 주입이 완료되면 작업판(A)을 3차원 프린터(P) 장치로부터 분리한 후 광확산수지가 경화될 때까지 기다린다. 광확산수지가 경화되는 동안 다른 작업판(A)을 3차원 프린터 장치에 설치하고, 새로운 측면부(100)를 동일한 방법으로 성형할 수 있다. 이와 같이 하나의 측면부(100)를 성형한 후 측면부(100)의 내부 공간에 주입된 광확산수지가 경화되는 동안 3차원 프린터(P)로 새로운 측면부(100)를 성형할 수 있기 때문에 입체간판의 생산성을 향상시킬 수 있다.When the injection of the light diffusion resin into the inner space of the side part 100 is completed, the working plate A may be separated from the 3D printer apparatus. A plurality of work plates (A) may be prepared and are detachably mounted to the three-dimensional printer (P) device. Accordingly, when the injection of the light-diffusion resin is completed, the work plate (A) is separated from the 3D printer (P) and waits until the light-diffusion resin is cured. While the light-diffusion resin is cured, another working plate A may be installed in the 3D printer apparatus, and a new side part 100 may be molded in the same manner. In this way, after molding one side part 100, while the light diffusion resin injected into the inner space of the side part 100 is cured, a new side part 100 can be molded with a three-dimensional printer (P). productivity can be improved.

또한, 작업판(A)은 필름(F) 상부에 측면부(100)를 성형한 후 3차원 프린터 장치로부터 분리할 수도 있다. 그리고 작업판(A)이 3차원 프린터(P) 장치로부터 분리된 상태에서 측면부(100)의 내부 공간에 광확산수지를 주입 후 경화시킨다.In addition, the working plate (A) may be separated from the 3D printer after forming the side portion 100 on the upper film (F). And in a state in which the working plate (A) is separated from the three-dimensional printer (P) device, the light diffusion resin is injected into the inner space of the side part 100 and then cured.

광확산수지가 경화되어 측면부(100)의 내측 하부에 광확산수지층(500)이 일체로 형성되면, 도 9에 도시된 바와 같이 서로 일체로 형성된 측면부(100)와 광확산수지층(500)과 필름(F)을 작업판(A)으로부터 분리한다. 전술한 바와 같이, 광확산수지층(500)의 표면은 측면부(100)의 하단과 동일한 위치에 평평하고 반듯하게 형성된다. 이러한 광확산수지층(500)은 측면부(100)의 일측을 차단하고, 입체간판의 정면이 된다.When the light-diffusion resin is cured and the light-diffusion resin layer 500 is integrally formed on the inner lower part of the side part 100, as shown in FIG. 9, the side part 100 and the light-diffusion resin layer 500 are integrally formed with each other. and the film (F) are separated from the working plate (A). As described above, the surface of the light diffusion resin layer 500 is formed flat and straight at the same position as the lower end of the side part 100 . This light-diffusion resin layer 500 blocks one side of the side part 100 and becomes the front side of the three-dimensional signboard.

도 8에 도시된 바와 같이, 작업판(A)과 분리된 측면부(100)는 내부 공간에 발광부를 설치한다. 발광부는 엘이디(L)와 결합판(600)으로 이루어지며 측면부(100)의 후방 또는 측면부(100)의 내부 공간에 결합된다. 결합판(600)을 측면부(100)의 후방 또는 측면부(100)의 내부 공간에 결합시키기 위하여 측면부(100) 성형단계에서 측면부(100)의 내측에 걸림부를 형성할 수도 있다.As shown in FIG. 8 , the side part 100 separated from the working plate A installs a light emitting part in the inner space. The light emitting part is made of an LED (L) and a coupling plate 600 and is coupled to the rear of the side part 100 or the inner space of the side part 100 . In order to couple the coupling plate 600 to the rear of the side part 100 or to the inner space of the side part 100 , a hooking part may be formed on the inside of the side part 100 in the forming step of the side part 100 .

측면부(100)의 성형 및 광확산수지층(500)의 경화가 완료되면, 상기 필름(F)위에서 열을 가하여 광확산수지층(500)과 필름(F)의 상호 접착력을 상실시키고, 필름(F)의 유연성을 증가시켜 필름(F)을 광확산수지층(500) 및 측면부(100)로부터 분리시킨다.When the molding of the side part 100 and curing of the light-diffusion resin layer 500 are completed, heat is applied on the film (F) to lose the mutual adhesion between the light-diffusion resin layer 500 and the film (F), and the film ( By increasing the flexibility of F), the film F is separated from the light diffusion resin layer 500 and the side part 100 .

이 과정에서 필름(F)의 상단 코팅면의 질감은 확산수지층(500)의 표면에 전사되어진다. 따라서, 광확산수지층(500)의 표면에 무광, 유광, 엠보 등의 질감을 표현할 수 있다.In this process, the texture of the upper coating surface of the film (F) is transferred to the surface of the diffusion resin layer (500). Accordingly, it is possible to express textures such as matte, glossy, and embossing on the surface of the light diffusion resin layer 500 .
