[규칙 제26조에 의한 보정 22.07.2016]　금속합금 필라멘트용 3D 프린터 [Correction 22.07.2016 by Rule 26] D 3D Printer for Metal Alloy Filaments

본 발명은 금속합금 필라멘트(650)를 노즐(600)에서 용해하고 압출하여 바닥 판(510)에 3차원 적층 물(520)을 생성하는 3D 프린터에 관한 것으로,The present invention relates to a 3D printer for dissolving and extruding the metal alloy filament 650 in the nozzle 600 to produce a three-dimensional stack 520 on the bottom plate 510,

보다 상세하게는 고주파 유도 가열코일(620)로 노즐을 가열하고 금속합금 필라멘트를 용해하고 압출하여 유사한 온도로 가열된 챔버(500) 내부의 하부 위치에 설치한 바닥 판에 한 층씩 적층 하므로 상호 간의 견고한 부착과 변형을 최소한 하는 금속합금 필라멘트용 3D 프린터에 관한 것이다.More specifically, the nozzles are heated with a high frequency induction heating coil 620, and the metal alloy filaments are melted and extruded to be laminated one by one on a bottom plate installed at a lower position inside the chamber 500 heated to a similar temperature. A 3D printer for metal alloy filaments with minimal adhesion and deformation.

종래의 3D 프린터는 히터 또는 고주파 유도가열을 이용하여 가열된 노즐에 공급된 열가소성 플라스틱 필라멘트 또는 금속합금 필라멘트를 녹여서 압출하고 바닥 판에 한 층씩 적층하여 3차원 조형물이 완성된다.Conventional 3D printers melt and extrude thermoplastic filaments or metal alloy filaments supplied to heated nozzles using a heater or high frequency induction heating, and layer them one by one on a bottom plate to complete a three-dimensional sculpture.

(참고특허문헌 2) 특허 CN 103786344 A (Reference Patent Document 2) Patent CN 103786344 A

일반 3D 프린터는 노즐에서 용해된 플라스틱 필라멘트 또는 금속합금 필라멘트를 외부와 열린 공간에서 가열된 바닥 판에 한 층씩 적층 하므로 3차원 적층 물과 필라멘트의 상호 간의 격심한 온도차이에 의하여 상호 간의 부착이 취약하고 3차원 조형물의 냉각으로 인한 수축작용으로 변형이 심한 단점이 있었다.In general 3D printers, the plastic filament or metal alloy filament melted from the nozzle is laminated one by one on the heated floor plate in the outside and in the open space. Therefore, due to the extreme temperature difference between the three-dimensional laminate and the filament, the adhesion between each other is weak. Due to the shrinkage action caused by the cooling of the three-dimensional sculptures, there was a serious disadvantage.

그러나 본 발명은 노즐과 유사한 온도로 가열된 챔버의 내부에 설치한 바닥 판에 금속합금 필라멘트를 고주파 유도 가열코일로 가열된 노즐에서 녹여서 압출하여 한 층씩 적층 하므로 3차원 적층 물의 상호 간의 견고한 부착과 수축작용으로 인한 변형을 작게 하는 것이다.However, the present invention melts and extrudes metal alloy filaments in a nozzle heated by a high frequency induction heating coil in a bottom plate installed in a chamber heated to a temperature similar to that of a nozzle, thereby stacking layers one by one, thereby firmly attaching and contracting the three-dimensional laminates. It is to reduce the deformation caused by the action.

전후, 좌우로 슬라이딩하는 하부 슬라이더 베드(200)의 상단위치에 외부와 열과 공기가 차단하고 히터로 가열된 챔버(500)를 설치한다.In the upper and lower positions of the lower slider bed 200 sliding back and forth, the outside and heat and air are blocked and the chamber 500 heated by the heater is installed.

상하로 슬라이딩하는 상부 슬라이더 베드(300)에 부착된 파이프 형상의 노즐 몸체(600)의 하부에 노즐을 설치한다.The nozzle is installed under the pipe-shaped nozzle body 600 attached to the upper slider bed 300 that slides up and down.

노즐에서 용해되어 압출되는 금속합금 필라멘트가 챔버의 내부의 하부 위치에 설치하여 노즐과 상대적으로 3차원으로 이동하는 바닥 판(510)에 한 층씩 적층 하여 3차원 적층 물(520)을 생성하는 것을 특징으로 한다.The metal alloy filament melted and extruded at the nozzle is installed at a lower position inside the chamber, and is laminated one by one on the bottom plate 510 moving in three dimensions relatively to the nozzle to generate a three-dimensional laminate 520. It is done.

외부공기와 열이 차단되고 가열된 챔버(500)의 내부에 불활성 가스통(700)에서 생성된 가스를 공급하여 금속합금 3차원 적층 물의 산화를 방지한다.External air and heat are blocked, and the gas generated in the inert gas cylinder 700 is supplied into the heated chamber 500 to prevent oxidation of the metal alloy 3D laminate.

본 발명은 용해되어 노즐에서 압출된 금속합금 필라멘트와 유사한 온도로 가열된 챔버의 내부에서 한 층씩 적층 하므로 상호 간의 견고한 부착과 변형이 적은 3차원 적층 물을 형성할 수 있는 효과가 있다.The present invention has the effect of forming a three-dimensional laminate with less firm adhesion and deformation between each other because it is laminated one by one inside the chamber heated to a temperature similar to the metal alloy filament melted and extruded from the nozzle.
