Description

3D 프린트용 기능성 원료공급 노즐장치{Material supply nozzle device}Technical Field [0001] The present invention relates to a material supply nozzle device for 3D printing,

본 발명의 3D 프린트용 기능성 원료공급 노즐장치에 관한 것으로, 더욱 상세하게는 노즐부의 이동에 따라 전선 및 원료공급 와이어의 꼬임을 방지하고, 다양한 제품을 생산하기 위해 다열구조의 와이어 공급기를 형성하여 3D 프린트의 효율적이고 고기능성을 높인 3D 프린트용 기능성 원료공급 노즐장치에 관한 것이다.The present invention relates to a functional material feed nozzle device for 3D printing, and more particularly, to a functional material feed nozzle device for 3D printing, more specifically, to prevent twisting of wires and a material supply wire according to movement of a nozzle portion, And more particularly, to a nozzle for supplying functional material for 3D printing with improved printing efficiency and high functionality.

일반적으로 3D 프린터는 2D 프린터에서 활자를 인쇄하는 것과 비슷하다. 2D 프린터는 컴퓨터에서 인쇄하기 버튼을 누르면 디지털화된 파일이 잉크젯 프린터로 전송되고, 프리터는 잉크를 종이 표면에 분사해 2D 이미지를 인쇄한다.Typically, a 3D printer is similar to printing type on a 2D printer. A 2D printer prints a 2D image by ejecting a digitized file onto an inkjet printer, which ejects the ink onto the paper surface.

3D 프린터의 기술은 다양하고 복잡하며 그 일예를 설명하면; The technology of 3D printers is diverse and complex;

한편, 한국특허 공개번호 제2001-0033833호는 3차원 물체 제조 방법 및 장치에 관한 것으로서, 보다 상세하게는 다수의 얇은 사전형성된 시트로 형성된 3차원 물체를 제조하는 장치로 상기 사전형성된 시트 각각은 대향된 측면상의 다음 인접한 시트에 대해 대향 측면상에 결합되고, 각각의 시트는 물체 내의 시트에 의해 구성된 개별층의 외곽선에 대응하는 외곽선을 따라 절단 공구에 의해 절단된다.Korean Patent Laid-Open Publication No. 2001-0033833 relates to a method and apparatus for manufacturing a three-dimensional object, and more particularly, to an apparatus for producing a three-dimensional object formed of a plurality of thinly pre-formed sheets, Wherein each sheet is cut by a cutting tool along an outline corresponding to an outline of an individual layer constituted by the sheet in the object.

또한, 상기 장치는 개별 외곽선을 따라 절단되고 상기 측면상의 다음 인접 시트에 결합되기 전에 상기 시트의 일측면에 피복재를 가하기 위한 박리제 애플리케이터를 포함하여, 박리제는 상기 물체 내의 개별 시트에 의해 구성된 층의 외곽선내의 시트의 표면을 덮지 않으며, 개별 시트가 절단되고 상기 측면상의 다음 인접 시트에 결합된 후 개별 외곽선 내의 시트의 표면만이 다음 인접 시트에 결합되어 상기 외곽선내에 있지 않는 개별 시트의 나머지 비결합 부분이 상기 다음 인접 시트 및 3차원 물체로부터 떨어지는 것을 특징으로 한다.The apparatus also includes a stripper applicator for cutting the sheet along the individual outline and applying a covering material to one side of the sheet before being joined to the next adjacent sheet on the side, Only the surface of the sheet within the individual outline is joined to the next adjacent sheet after the individual sheet is cut and joined to the next adjacent sheet on the side so that the remaining unjoined portion of the individual sheet that is not in the outline The next adjacent sheet and the three-dimensional object.

그러나, 상기 종래와 같은 기술은 얇은 시트를 적층하여 3차원으로 조형물을 만드는 형태는 재료를 융융시켜 만드는 조형물에 비해 조형물의 이음매가 매끄럽지 못한 문제점이 있다.However, the above-mentioned conventional technique has a problem in that the shape of the three-dimensionally laminated thin sheets is inferior to the shape of the formed material by melting the material.

다른 일예인 열가소성 소재(플라스틱)를 실처럼 자아낸 고체상태인 필라멘트를 이용한 조형 방식에는 대표적으로 FDM (Fused Deposition Modeling)방식이 있는데, 이는 열가소성 수지를 압출하여 적층하며 조형하는 방식으로, 압출기를 통해 필라멘트를 공급하면, 공급된 필라멘트는 필라멘트를 녹일 수 있는 온도로 가열된 노즐을 통해 액체상태로 압출되어 한 층씩 적층되며 조형물이 완성된다.FDM (Fused Deposition Modeling) method is a typical molding method using a filament which is a solid state in which a thermoplastic material (plastic) as another example is thread-like. This is a method in which a thermoplastic resin is extruded and laminated and molded, The supplied filament is extruded in a liquid state through a nozzle heated to a temperature at which the filament can be melted and laminated one by one to complete the molding.

This is a method in which a thermoplastic resin is extruded and laminated and molded. When a filament is fed through an extruder , The fed filament is fed through a nozzle heated to a temperature at which the filament can be melted

해 액체상태로 압출되어 한 층씩 적층되며 조형물이 완성된다.It is extruded in a liquid state and stacked one layer at a time, and the sculpture is completed.

종래 FDM방식 3차원 프린터의 압출기는 하나의 공급기에 하나의 노즐로 구성되어 다양한 재료의 사용, 다양한 색 변경하는 것이 한계가 있다는 문제점이 있었다. 상기와 같은 문제점을 해결하기 위하여, 멀티 노즐을 구현하는 연구가 활발히 진행되고 있으나, 멀티 노즐이 연동되어 동일평면상에 위치하고 있을 경우 프린트 중에 작동하지 않는 노즐이 조형물과 접촉하여 조형물이 베드로부터 떨어질 수 있다는 문제점이 있다. 또한 노즐이 이동경로가 바뀌는 지점에서 정지한 후 다음 압출 구간으로 이동할 때 과다 압출이나 미달 압출이 발생되어 동일평면상 보다 높은 구간이 발생할 수 있다는 문제점이 있다.There has been a problem that the extruder of the conventional FDM type three-dimensional printer is constituted of one nozzle in one feeder, and there is a limitation in using various materials and changing various colors. In order to solve the above problems, research has been actively carried out to realize multi-nozzles. However, when multi-nozzles are interlocked and positioned on the same plane, nozzles that do not operate during printing come into contact with the molding objects, . In addition, when the nozzle is stopped at a point where the movement path is changed and then moved to the next extrusion section, there is a problem that excessive extrusion or under-extrusion occurs and a section higher than the same plane may occur.
