Description
본발명은 기존의 광경화 폴리머의 강도를 증가시키고, 전도성을 부가할 수 있으며, 이를 통해 다양한 전자소자의 3D 프린팅이 가능한 3D프린터용 광경화 폴리머에 관한 것이다.The present invention relates to a photocurable polymer for a 3D printer capable of 3D printing of various electronic devices by increasing the strength of the existing photocurable polymer and adding conductivity.
일반적으로 성형을 위해 종래의 절삭가공이나 사출가공외 3D 프린터 방식이 사용되며, 일례로서 공개특허공보 공개번호 10-2018-0109646호에 종래기술로 기재된 바와 같이, 3D 프린터의 종류로서, FDM(Fused Deposition Medeling), SLA(Stereo Lithography Apparatus), SLS(Selective Laser Sintering), DLP(Digital Light Processing) 방식의 3D 프린터가 있는데, 현재 보급형으로 판매 되고 있는 3D 프린터는 상기 FDM 방식이 주를 이루고 있다. 상기 보급형 FDM방식의 3D 프린터의 이용 목표는 외관 및 형상을 보는 것에 있다. 그러나 상기 FDM 방식의 3D 프린터는 기계적인 움직임이 많기 때문에 형상 제작 과정에서 실패율이 높아 문제가 되고 있다.In general, a 3D printer method other than conventional cutting or injection processing is used for molding. As an example, as described in the prior art in Korean Patent Publication No. 10-2018-0109646, as a type of 3D printer, FDM (Fused There are 3D printers of Deposition Medeling), Stereo Lithography Apparatus (SLA), Selective Laser Sintering (SLS), and Digital Light Processing (DLP), and the FDM method is the main 3D printer currently sold as a popular type. The purpose of using the popular FDM type 3D printer is to see the appearance and shape. However, since the FDM type 3D printer has a lot of mechanical movement, it is a problem due to a high failure rate in the shape manufacturing process.
이러한 FDM 방식의 3D 프린터와는 달리 SLA 또는 DLP 방식의 3D 프린터는 액상의 광경화성 수지에 빛을 조사하여 경화시키는 것으로 조형물을 제작하는 기기로서, 자외선 빛을 이용한 경화방식을 이용하기 때문에 기구적 움직임(Z축)이 최소이고 형상 제작시 실패율이 낮아 향후 3D 프린팅 방식에서 FDM 방식을 보완하여 많이 사용할 것으로 예상된다. SLA 또는 DLP 방식의 3D 프린터는 아크릴, 우레탄, 에폭시 중 하나 이상을 포함하는 광경화성 고분자(photopolymer) 수지에 빛(가시광선)을 조사하여 3차원 형상의 플라스틱 조형물을 제작하는 기기이다. 즉 CAD 시스템으로 모델링한 3차원 형상을 0.05~0.1mm 두께의 다수의 층으로 분할한 후, 이들 각 층을 슬라이스데이터(slice data)로 변경하고, 이를 사용하여 광경화성 수지에 빛을 조사하면서 한층 또 한층 차례로 경화시키면서 적층함으로써 조형물을 완성하는 방식으로 각종 형태의 플라스틱 모델을 제조하고 있다.Unlike the FDM type 3D printer, the SLA or DLP type 3D printer is a device that makes a sculpture by irradiating light onto a liquid photocurable resin and curing it. Because it uses a curing method using ultraviolet light, it moves mechanically. The (Z-axis) is the minimum and the failure rate is low during shape production, so it is expected that the FDM method will be supplemented and used a lot in the future 3D printing method. The SLA or DLP type 3D printer is a device that produces a three-dimensional plastic sculpture by irradiating light (visible light) on a photopolymer resin containing at least one of acrylic, urethane, and epoxy. In other words, after dividing the three-dimensional shape modeled with the CAD system into a number of layers with a thickness of 0.05 to 0.1 mm, each of these layers is converted into slice data, and using this, the photocurable resin is irradiated with light. In addition, various types of plastic models are manufactured by laminating them while curing them one by one to complete the sculpture.

그러나 상기 종래 3D프린터 재료로서 광경화 폴리머는 강도가 약하며 도전효과가 없어서 사용이 제한되는 단점이 있었다.However, as the conventional 3D printer material, the photocurable polymer has a disadvantage in that its use is limited due to its weak strength and no conductive effect.
본 발명은 상술한 문제점을 해결하기 위하여 안출된 것으로, 광경화 폴리머의 강도를 증가시키고, 전도성을 부가할 수 있으며, 이를 통해 다양한 전자소자의 3D 프린팅이 가능한 3D프린터용 광경화 폴리머를 제공하고자 하는 것이다.The present invention has been devised to solve the above-described problems, and it is possible to increase the strength of the photocurable polymer and add conductivity, thereby providing a photocurable polymer for a 3D printer capable of 3D printing of various electronic devices. will be.
본발명은 3D프린터용 광경화 폴리머에 관한 것으로, 합성수지와 구리나노와이어로 이루어지는 것으로, 상기 합성수지와 구리나노와이어의 조성비는 합성수지 95 ~ 99중량%, 구리나노와이어 1 ~ 5중량%인 것을 특징으로 한다.The present invention relates to a photocurable polymer for a 3D printer, comprising a synthetic resin and a copper nanowire, wherein the composition ratio of the synthetic resin and copper nanowire is 95 to 99% by weight of synthetic resin and 1 to 5% by weight of copper nanowire do.
따라서 본발명은 구리나노와이어를 광경화 수지와 배합하여 경화 후 강도를 증가시키고 전도성 나노와이어들을 통한 도전성을 확보하여 전기소자로 활용 가능한 3D 프린팅 제품을 만들 수 있는 현저한 효과가 있다. Therefore, the present invention has a remarkable effect of making a 3D printing product that can be used as an electric device by mixing copper nanowires with a photocurable resin to increase the strength after curing and secure conductivity through conductive nanowires.
본발명은 3D프린터용 광경화 폴리머에 관한 것으로, 합성수지와 구리나노와이어로 이루어지는 것을 특징으로 한다.The present invention relates to a photocurable polymer for a 3D printer, and is characterized by consisting of a synthetic resin and a copper nanowire.
또한, 상기 합성수지와 구리나노와이어의 조성비는 합성수지 95 ~ 99중량%, 구리나노와이어 1 ~ 5중량%인 것을 특징으로 한다.In addition, the composition ratio of the synthetic resin and the copper nanowire is characterized in that 95 to 99% by weight of the synthetic resin and 1 to 5% by weight of the copper nanowire.

조성비는 합성수지 95 ~ 99중량% 에 대하여 1 ~ 5중량% 혼합한다. 합성수지는 아크릴, 우레탄, 에폭시중 어느 하나이다. 구리나노와이어 비율이 너무 작으면 본발명의 강도증가나 도전효과가 미약하며 비율이 너무 많으면 성형성이 떨어지므로 합성수지와 구리나노와이어의 조성비는 합성수지 95 ~ 99중량%, 구리나노와이어 1 ~ 5중량%로 제조한다. 최적치는 합성수지 97중량%, 구리나노와이어 3중량%로 제조한다.The composition ratio is mixed with 1 to 5% by weight based on 95 to 99% by weight of the synthetic resin. Synthetic resin is any one of acrylic, urethane, and epoxy. If the copper nanowire ratio is too small, the strength increase or the conductive effect of the present invention is weak, and if the ratio is too high, the moldability is poor, so the composition ratio of synthetic resin and copper nanowire is 95 to 99% by weight of synthetic resin, 1 to 5 weight of copper nanowire Manufactured in %. The optimum value is prepared with 97% by weight of synthetic resin and 3% by weight of copper nanowires.

Therefore, it is used for decoration. The composition ratio is prepared from 1 to 5 parts by weight of copper nanowire and 0.5 to 1 part by weight of phosphorus based on 95 to 99 parts by weight of synthetic resin.
또한 레이저에 의한 경화시 구리나노와이어 접점에 멜팅효과가 있어 저항이 현저히 줄어들어 도선성을 증가시키는 효과도 있다.In addition, when curing by laser, there is a melting effect on the copper nanowire contact point, so that resistance is remarkably reduced, thereby increasing the leadability.
