Field of the Invention The present invention relates to a three-dimensional printing method using charged polymer particles, and more particularly, to a three-dimensional printing method capable of forming a large-sized solid object in a short time by printing using an electrostatic printing method using charged particles.
일반적으로 3차원 구조의 입체물 생성을 위해서는 3차원 디지털 모델이 필요하며, 이를 이용하여 다양한 인쇄 방식으로 입체물을 복제하게 된다. 예를 들어 수가공으로 제작한 시제품, 골동품, 경쟁 제품, 신체 부분에 대한 형상 측정 등이 전형적으로 역설계 기술을 이용한 복제 작업이 활용되는 대표적인 분야이다. Generally, a three-dimensional digital model is required for generating a three-dimensional structure, and the three-dimensional model is replicated using various printing methods. For example, prototypes, antiques, competing products, and shape measurements of body parts made of water-repellent materials are typically used to replicate using reverse engineering techniques.
상기 입체물을 형성하기 위한 3차원 인쇄 방법으로서 종래에는 잉크젯프린트 방식의 기술을 집약시켜 자외선 경화성 수지를 인쇄하고 자외선을 조사하여 경화시키면서 모형의 단면을 세분화시켜 인쇄 적층 하는 방식을 예시할 수 있다. 이를 위한 ABS와 같은 수지계가 주로 사용된다.As a three-dimensional printing method for forming the three-dimensional object, conventionally, a method of printing and stacking ultraviolet ray-curable resin by curing the ultraviolet ray-curing resin by curing the ultraviolet ray-curing resin while aggregating the technique of the inkjet printing method is exemplified. A resin system such as ABS is mainly used for this purpose.
상기 인쇄 방법에서 출력방식은 크게는 잉크젯프린트의 기계로 버블젯 방식의 노즐에 순간적인 열을 가하여 발생하는 소재의 기포 방울을 신호에 따라 생성하여 소재를 밀어내는 방식과, 마하젯 분사방식의 압전소자인 피에조 노즐에 입력되는 신호에 따라 뒤쪽의 플레이트가 줄어드는 크기를 조절하는 것으로 미세한 소재를 분사하는 방식과 써멀젯방식, 즉 열 전사 방식으로도 불리는 것으로 순간적인 고열로 잉크를 분사하는 방식 등이 사용되고 있다.In the printing method, the output method is roughly classified into a method in which bubble drops of a material generated by instantaneous heat are applied to a nozzle of a bubble-jet type by a machine of an ink-jet printing to push out the material by a signal, By controlling the size of the back plate shrinking according to the signal input to the piezo nozzle, the device is able to control the injection of fine material, and the thermal jet method, that is, the thermal transfer method, .
그러나 상기와 같은 3차원 인쇄 방법은 20cm 정도의 높이를 갖는 입체물 형성시 대략 12시간 내지 24시간의 장시간이 소요되며, 정밀도가 0.5 내지 0.01mm에 불과하다는 문제가 있다.However, in the above-described three-dimensional printing method, a long time of about 12 to 24 hours is required for forming a three-dimensional object having a height of about 20 cm, and the accuracy is only 0.5 to 0.01 mm.

It is also possible to use particles having various diameters in a mixed manner.
상술한 바와 같은 하전된 고분자 입자는 정전 인쇄 방식에 채용되어 3차원 입체물을 형성할 수 있다. 상기 정전 인쇄 방식은 상기 하전된 고분자 입자를, 이와 반대 전하를 갖는 플레이트에 정전기적으로 부착시킨 후, 이를 목적하는 기재 상에 전사하여 상기 고분자 입자로 된 소정 형상의 레이어를 형성할 수 있다. 상기 플레이트는 MOSFET과 같은 반도체가 픽셀 형태로 구성된 평면 구조체로서 상기 픽셀에 전하를 부여할 수 있는 별도의 구동회로를 가질 수 있다.The charged polymer particles as described above can be employed in an electrostatic printing method to form a three-dimensional solid body. In the electrostatic printing method, the charged polymer particles can be electrostatically attached to a plate having an opposite charge, and then transferred to a target substrate to form a layer of a predetermined shape of the polymer particles. The plate may have a separate driving circuit capable of imparting charge to the pixel as a planar structure in which a semiconductor such as a MOSFET is formed in the form of a pixel.
상기 정전 인쇄 방식의 3차원 인쇄 방법을 각 공정별로 도 1에 도시한다.The electrostatic printing type three-dimensional printing method is shown in Fig. 1 for each step.
도 1을 참조하면, A, B, C 및 D의 4가지 공정으로 나눌 수 있으며, A 공정에서 하전된 고분자 입자에 반대 전하를 갖는 플레이트가 정전기적으로 접촉하게 된다. 여기서 상기 플레이트는 구동 스위치를 통해 각 픽셀에 전하가 인가될 수 있으며 그에 따라 목적하는 잠상의 형태로 상기 플레이트에 전하를 국부적으로 인가하는 것이 가능하다. 이때 상기 하전된 고분자 입자는 상기 플레이트의 면 전체에 고르게 부착될 수 있다. 즉, 점 단위로 부착되는 것이 아니라, 플레이트의 일면에 걸쳐 고르게 부착될 수 있다.Referring to FIG. 1, the process A, B, C, and D can be divided into four processes. In the process A, the plate having the opposite charge is brought into electrostatic contact with the charged polymer particles. Wherein the plate is capable of applying charge to each pixel through a drive switch and thereby locally apply charge to the plate in the form of a desired latent image. At this time, the charged polymer particles can be uniformly attached to the entire surface of the plate. That is, they may be attached uniformly over one surface of the plate, not on a point-by-point basis.
상기 A 공정에서, 하전된 고분자 입자는 용기 상에 수용된 상태로 존재하는 바, 이때 분말상 또는 용매, 예를 들어 물에 재분산된 형태로 존재하는 것도 가능하다. 이때 분산성을 개선하기 위하여 상기 고분자 입자의 표면 전하와 동일한 극성의 계면활성제 또는 안정제를 더 첨가할 수 있다. In the process A, the charged polymer particles are present in a state of being accommodated in the container, and may be present in the form of powder or redispersed in a solvent, for example, water. At this time, a surfactant or stabilizer having the same polarity as the surface charge of the polymer particle may be further added to improve dispersibility.
B 공정에서는 상기 플레이트의 소정 영역(상기 하전된 고분자 입자와 반대 전하를 갖는 영역)에 상기 하전된 고분자 입자가 정전기적으로 부착되어 있음을 알 수 있다. 이러한 부착 단계에서는 상기 플레이트에 전원을 계속 인가하여 반대 전하를 유지시킬 필요가 있다.In step B, it can be seen that the charged polymer particles are electrostatically adhered to a predetermined region of the plate (a region having opposite charge to the charged polymer particles). In this attaching step, it is necessary to keep the opposite charge by continuously applying power to the plate.
이어지는 C 공정에서 상기 하전된 고분자 입자는 플레이트에 부착된 상태로 기재 상으로 이동된다. 여기서 상기 플레이트에 인가된 전원을 중단시키면 상기 고분자 입자는 기재 상에 전사된다. 이때 상기 하전된 고분자 입자는 면 단위로 이동이 가능하므로 다량의 입자를 동시에 전사하는 것이 가능해진다. 따라서 점 단위의 인쇄 방식에 비해 속도를 수십배 이상 개선할 수 있으며, 상기 고분자 입자의 크기를 나노미터 수준으로 작게 할 경우 정밀도 또한 크게 개선하는 것이 가능해진다.In the subsequent step C, the charged polymer particles are transferred onto the substrate in a state of being attached to the plate. When the power applied to the plate is stopped, the polymer particles are transferred onto the substrate. At this time, since the charged polymer particles can move on a plane basis, a large amount of particles can be transferred at the same time. Therefore, the speed can be improved by several tens of times or more as compared with the point-by-point printing method, and when the size of the polymer particles is reduced to the nanometer level, the precision can be greatly improved.
상기와 같이 전사된 고분자 입자는 이어지는 과정에서 레이져로 소결처리되거나 열처리될 수 있다.The polymer particles thus transferred may be sintered or heat treated with a laser in the subsequent process.
상기 도 1에 도시한 전사 공정을 층별로 반복하여 복잡한 형상의 입체 형상을 구성할 수 있으며, 이때 상기 플레이트에 전원을 인가하는 구동회로는 별도의 디지털 시스템에 연결되어 각 픽셀별로 디지털화된 레이어 단위 화상을 도입하는 것이 가능하다.The transfer process shown in FIG. 1 may be repeated for each layer to form a complicated three-dimensional shape. In this case, the driving circuit for applying power to the plate is connected to a separate digital system, Can be introduced.
상기 전사 공정을 반복하는 경우, 양이온성으로 하전된 고분자 입자와 음이온성으로 하전된 고분자 입자를 번갈아 적층하는 것이 효율성을 보다 개선할 수 있게 된다.When the transfer process is repeated, it is possible to improve the efficiency by alternately stacking cationically charged polymer particles and anionically charged polymer particles.
상기와 같은 3차원 인쇄 방법은 다양한 인쇄기에서 유용하게 사용되어 정밀도가 높은 입체물을 형성할 수 있다.The above-described three-dimensional printing method can be advantageously used in various printing machines to form a three-dimensional object with high precision.
