본 특허출원은 2019년 04월 29일에 대한민국 특허청에 제출된 대한민국 특허출원 제10-2019-0050136호에 대하여 우선권을 주장하며, 상기 특허출원의 개시 사항은 본 명세서에 참조로서 삽입된다.This patent application claims priority to Korean Patent Application No. 10-2019-0050136 filed with the Korean Intellectual Property Office on April 29, 2019, and the disclosures of the patent application are incorporated herein by reference.
본 발명은 3차원 프린터에 의해 제조된 성형물을 세척하는 3차원 성형물 세척장치에 관한 것으로, 보다 구체적으로는 자기장에 의해 구동되는 회전 막대의 회전으로 세척액의 와류(vortex) 또는 진동을 발생시키고, 와류 또는 진동이 발생된 세척액으로 3차원 프린터에 의해 제조된 성형물을 세척할 수 있는 3차원 성형물 세척장치에 관한 것이다.The present invention relates to a three-dimensional molded object washing apparatus for washing a molded object manufactured by a three-dimensional printer, and more specifically, a vortex or vibration of the washing liquid is generated by rotation of a rotating rod driven by a magnetic field, and Or, it relates to a three-dimensional molded object washing apparatus capable of washing a molded object manufactured by a three-dimensional printer with a washing liquid generated by vibration.
일반적으로 3차원 입체 형상을 가진 시제품을 제작하기 위해서는 도면에 의존하여 수작업에 의해 이루어지는 목합 제작 방식과 CNC 밀링에 의한 제작 방법 등이 널리 알려져 있다.In general, in order to produce a prototype having a three-dimensional three-dimensional shape, a method of manufacturing a wood composite by hand depending on a drawing and a method of manufacturing by CNC milling are widely known.
그러나, 목합 제작 방식은 수작업에 의존하므로 정교한 수치 제어가 어렵고 많은 시간이 소요되며, CNC 밀링에 의한 제작 방법은 정교한 수치 제어가 가능 하지만 공구 간섭으로 인해 가공하기 어려운 형상이 많다.However, since the woodwork manufacturing method relies on manual labor, precise numerical control is difficult and takes a lot of time, and the manufacturing method by CNC milling enables precise numerical control, but there are many shapes that are difficult to process due to tool interference.
따라서 최근에는 제품의 설계자가 CAD 또는 CAM을 이용하여 3차원 모델링 데이터를 생성하고, 생성한 데이터를 이용하여 3차원 입체 형상의 시제품을 제작하는 이른바 3차원 프린팅 방식이 전 산업분야에서 응용되고 있다.Therefore, in recent years, a so-called 3D printing method in which a product designer creates 3D modeling data using CAD or CAM and produces a prototype of a 3D stereoscopic shape using the generated data has been applied in all industrial fields.
3차원 프린팅 방식에는 광경화성 수지에 레이저 또는 특정 파장의 빛을 주사하여 주사된 부분이 경화되는 원리를 이용한 SLA(Stereo Lithographic Apparatus) 또는 DLP(Digital Light Precessing), SLA 또는 DLP의 광경화성 수지 대신에 기능성 고분자 또는 금속 분말을 사용하며 레이저 광선을 주사하여 소결성형하는 원리를 이용한 SLS(Selective Laser Sintering), 접착제가 칠해져 있는 종이를 원하는 단면으로 레이져 광선을 이용하여 절단하여 한 층씩 적층하여 성형하는 LOM(Laminated Object Manufacturing), 및 잉크젯(Ink Jet) 프린터 기술을 이용한 BPM(Ballistic Particle Manufacturing) 등이 있다. 분말을 기반으로 하는 SLS(Selective Laser Sintering) 방식의 3차원 프린터는, 플랫폼 위로 미세분말을 공급하여 적층함으로써 3차원 물체를 형성시킬 수 있다.In the 3D printing method, instead of SLA (Stereo Lithographic Apparatus) or DLP (Digital Light Precessing), SLA or DLP photocurable resin using the principle that the scanned part is cured by scanning a laser or light of a specific wavelength on a photocurable resin. Selective Laser Sintering (SLS) using the principle of sintering molding by scanning a laser beam using functional polymer or metal powder, and LOM (selective laser sintering), which cuts the adhesive-coated paper into a desired cross-section using laser beams and laminates one layer at a time. Laminated Object Manufacturing), and BPM (Ballistic Particle Manufacturing) using ink jet printer technology. In the powder-based SLS (Selective Laser Sintering) type 3D printer, a 3D object can be formed by supplying and laminating fine powder on a platform.
상기와 같이, 적층 공정을 통해 3차원 물체를 형성하는 경우, 일반적으로 적어도 1 종류의 재료를 토출하는 공정이 포함될 수 있다. 이때, 재료는 물체의 구조를 형성하기 위해 사용되는 성형(build)재료이다. 특히, 성형 재료는 3차원 물체가 완성되면 구조물 주위에 경화되지 않은 재료들이 묻어 있다. 경화되지 않은 재료는 제거되어야 하는데, 예를 들어, 알코올이 담긴 통에 넣어 흔들어 세척해야 한다. As described above, when forming a 3D object through the lamination process, a process of discharging at least one type of material may generally be included. In this case, the material is a build material used to form the structure of the object. In particular, in the molding material, when a 3D object is completed, uncured materials are buried around the structure. The uncured material must be removed, for example, washed by shaking it in a bucket filled with alcohol.
이때, 2 종류의 재료 중 하나는 물체의 구조체를 형성하기 위해 사용되는 성형(build) 재료이고, 다른 하나는 물체의 구조가 완전하게 경화할 때까지 성형 재료를 지지하는 지지 재료로 구성될 수 있다.At this time, one of the two types of materials is a build material used to form the structure of the object, and the other may be composed of a support material that supports the molding material until the structure of the object is completely cured. .
지지 재료는 3차원 물체가 충분히 경화될 때까지 극히 얇은 층, 예를 들어 16-30㎛의 두께로 제공되며, 지지 및 성형 재료 모두는 동시에 또는 순차적으로 각각의 층에 토출되어 3차원 물체를 형성할 수 있다.The support material is provided in extremely thin layers, e.g. 16-30 μm thick, until the three-dimensional object is sufficiently cured, and both the support and molding materials are ejected simultaneously or sequentially to each layer to form a three-dimensional object. can do.
특히, 3차원 물체가 완료되면 지지 재료는 제거되어야 하는데, 예를 들어, 공기 또는 유체 온도가 지지 재료의 융점 이상인 오븐 또는 가열된 액체 조에 넣어 지지 재료를 용융시켜 제거하거나, 또는 세척액을 통해 지지 재료를 제거할 수 있다. 또한, 액상 레진을 사용하는 3차원 프린터로 제조된 3차원 물체의 경우, 제조된 물체에 잔류하는 잔여 액상 레진을 제거하는 공정을 거쳐야 한다.In particular, when the three-dimensional object is completed, the support material must be removed, for example, by melting the support material by placing it in an oven or a heated liquid bath where the air or fluid temperature is above the melting point of the support material, or removing the support material through a cleaning solution. Can be removed. In addition, in the case of a 3D object manufactured by a 3D printer using liquid resin, a process of removing residual liquid resin remaining on the manufactured object must be performed.
