본 발명은 3D 프린터 전용의 UV 후경화장치에 관한 것으로, 좀 더 구체적으로 설명하면 광경화수지(Photo Polymer)로 제작된 대상물에 UV 광원을 집중적으로 균일하게 조사하고, 용도에 맞게 광량을 제어하여 최상의 경화품질을 가지면서 최적의 방열구조를 갖춘 UV 후경화장치에 관한 것이다.The present invention relates to a UV post-curing device exclusively for 3D printers, and more specifically, to intensively and uniformly irradiating a UV light source to an object made of a photocuring resin (Photo Polymer), and controlling the amount of light according to a use. The present invention relates to a UV post-curing device having an optimal heat dissipation structure with the best curing quality.

과거에는 제품을 생산하기 전에 그 대상물을 보기 위하여 3D프로그램을 통해 만들어진 대상물의 데이터를 2D프린터를 사용하여 평면상에 인쇄하듯이 출력하는 방식으로 사용되었으나, 이러한 2D방식은 정확한 대상물을 파악할 수 없는 단점이 있었다.In the past, this method was used to print the data of the object created by the 3D program before printing the product as if it is printed on a plane using a 2D printer, but this 2D method cannot identify the exact object. There was this.

따라서 최근에는 대상물을 3D데이터를 이용하여 그 대상물을 3차원, 즉 X축(앞뒤)과 Y축(좌우)과 Z축(상하) 제어를 통해 입체적으로 만들어내는 3D프린터가 많이 사용되고 있다.Therefore, in recent years, 3D printers that use the 3D data to create the object in three dimensions, that is, the three-dimensional control through the X-axis (front and rear), Y-axis (left and right) and Z-axis (up and down) has been widely used.

상기 3D프린터는 3가지 출력방식이 있으며, 고체재료를 녹여서 적층하는 FDM(Fused Deposition Modeling)방식, 분말재료를 레이저를 이용하여 소결시키는 SLS(Selective Laser Sintering)방식과 액체재료를 레이저 또는 빛으로 경화시키면서 쌓아올리는 DLP(Digital Light Processing)/SLA(Stereolithography Apparatus)방식으로 되어 있다.The 3D printer has three output methods, a FDM (Fused Deposition Modeling) method for melting and stacking solid materials, a SLS (Selective Laser Sintering) method for sintering powder materials using a laser, and curing liquid materials with laser or light. DLP (Digital Light Processing) / SLA (Stereolithography Apparatus) is stacked.

또한, 입체형태의 제작물의 최종 표면 처리과정에서 광경화수지 재료를 용도에 따라 사용되기도 한다.In addition, a photocurable resin material may be used depending on the application in the final surface treatment of the three-dimensional article.

본 발명은 광경화수지(Photo Polymer)를 사용하는 방식의 3D 프린터로 출력되는 대상물을 경화하는 UV-A 파장대를 갖춘 후경화장치에 관한 것이다.The present invention relates to a post-curing apparatus having a UV-A wavelength band for curing an object output to a 3D printer using a photocurable resin.

상기 방식의 3D프린터는 빛에 반응하여 경화되는 광경화수지가 주재료로 사용되며, 출력된 대상물이 사용 용도에 적합하게 경화되기까지 최소 24시간에서 최대 48시간의 장시간이 소요되는 단점이 있다.The 3D printer of the above method is a photocurable resin which is cured in response to light is used as a main material, and it has a disadvantage that it takes a long time of at least 24 hours to a maximum of 48 hours before the output object is cured for use.

즉, 출력된 대상물을 최종 목적에 맞게 사용하기 위해 너무 많은 시간이 소요되는 문제로 인해서 생산과정에서의 소요시간이 크게 발생되고, 출력된 대상물을 보완이나 수정하는 과정 등이 발생될 경우에는 대상물의 3D데이터를 수정 후 재출력하여 경화하기까지 추가적인 시간이 더 많이 소요되기 때문에 시간지연으로 인한 출력되는 대상물의 생산성이 저하되는 문제가 있는 것이다.In other words, due to the problem that it takes too much time to use the printed object according to the end purpose, the time required in the production process is greatly generated, and the process of supplementing or modifying the printed object occurs. Since it takes more time to correct the 3D data after reprinting and hardening, there is a problem that the productivity of the output object is reduced due to time delay.

따라서 최근에 출력된 대상물을 빠르게 경화시키기 위하여 UV 후경화장치를 사용하고 있는 것이다.Therefore, in order to quickly cure the recently printed object is using a UV post-curing device.

이러한 UV 후경화장치는 대상물을 수용하는 케이스의 내부에 자외선을 조사하는 UV LED를 장착하여 경화속도를 약 30분 안에 빠르게 경화되도록 한 것이다. The UV post-curing device is equipped with a UV LED that irradiates ultraviolet rays inside the case accommodating the object so that the curing speed can be quickly cured in about 30 minutes.

그러나 이러한 UV 후경화장치는, 대상물의 액체소재에 따라 경화되는 시간이 서로 다르고, 상기 대상물의 형상 역시 3D데이터에 의해 입체적으로 이루어지면서 UV 광원이 균일하게 조사되기 어려워 완전한 경화가 이루어질 때까지 오랜 시간이 소요되고,However, the UV post-curing apparatus has different curing times depending on the liquid material of the object, and the shape of the object is also made three-dimensionally by 3D data, so that it is difficult to irradiate the UV light source uniformly so that a long time is achieved until complete curing is achieved. This takes

특히 UV LED가 120도 이상의 광각을 가지고 있기 때문에 대상물과 UV LED 사이의 거리가 멀어질수록 광량이 감소하여 대상품의 경화품질을 저하시키고 광원소자의 설치 위치에 따라 대상물의 표면에 조사되지 않는 사각 위치가 형성되는 문제점이 있던 것이다.In particular, since the UV LED has a wide angle of more than 120 degrees, as the distance between the object and the UV LED increases, the amount of light decreases, which reduces the curing quality of the large product and does not irradiate the surface of the object depending on the installation position of the light source element. There was a problem that the position is formed.

더욱이 종래의 UV LED는 케이스 안쪽에 설치되어 장시간 사용되고, 이때 발생하는 열기가 효과적으로 외부로 배출되지 않아 UV LED의 수명이 짧아져 자주 교환해 주어야 하거나 광효율이 저하되는 문제점이 있고, 이때 발생하는 열기가 내측에 위치한 대상물에 영향을 끼쳐 변형 및 변색을 초래하는 문제점도 있었던 것이다.Moreover, the conventional UV LED is installed inside the case and used for a long time, and since the heat generated at this time is not effectively discharged to the outside, the life of the UV LED is shortened, so there is a problem that frequent replacement or deterioration of the light efficiency occurs. There was also a problem that affects the object located inside, causing deformation and discoloration.

또한, 최근에는 3D 스캐너로 치아의 3D 데이터를 확보한 후, 이를 이용해 3D 프린터로 치과용 제작물을 만드는 방법이 제시되고 있고, 이럴 경우에는 출력된 대상물의 경화작업을 완료한 후에 구강내 사용을 위해 별도로 살균작업을 추가해야 하는 만큼 생산공정이 복잡하고 많은 시간이 소요되는 단점으로 작업의 효율성이 매우 떨어지는 문제가 있는 것이다.In addition, recently, a method of making a dental product using a 3D printer after securing 3D data of a tooth with a 3D scanner has been proposed, and in this case, it is used for oral use after completion of curing of the printed object. The production process is complicated and time-consuming as it is necessary to add a separate sterilization operation is a problem that the work efficiency is very low.
