The present invention relates to a nozzle assembly capable of producing a three-dimensional sculpture having magnetism having a magnetization direction oriented in one direction, a three-dimensional printer comprising same, a three-dimensional printing method, and an electronic component case manufactured using same. The nozzle assembly may comprise: a discharge part body; a material supplying part formed on the upper end of the discharge part body to supply a material supplied from a material supply device; a material melting part connected to the end of the material supplying part in the discharge part body and melting the material supplied through the material supplying part; a magnetic field applying part connected to the end of the material melting part in the discharge part body and applying a magnetic field to the melted material to allow metal powder included in the material to be magnetized; and a discharge part connected to the end of the magnetic field applying part in the discharge part body to be formed at the lower end of the discharge part body and discharging the melted material. La présente invention concerne un ensemble buse capable de produire une sculpture tridimensionnelle ayant un magnétisme ayant une direction de magnétisation orientée dans une direction, une imprimante tridimensionnelle comprenant celui-ci, un procédé d'impression en trois dimensions, et un boîtier de composant électronique fabriqué à l'aide de celui-ci. L'ensemble buse peut comprendre : un corps de partie de décharge ; une partie d'alimentation en matériau formée sur l'extrémité supérieure du corps de partie de décharge pour fournir un matériau fourni à partir d'un dispositif d'alimentation en matériau ; une partie de fusion de matériau reliée à l'extrémité de la partie d'alimentation en matériau dans le corps de partie de décharge et faisant fondre le matériau fourni à travers la partie d'alimentation en matériau ; une partie d'application de champ magnétique reliée à l'extrémité de la partie de fusion de matériau dans le corps de partie de décharge et appliquant un champ magnétique au matériau fondu pour permettre à la poudre métallique incluse dans le matériau d'être magnétisée ; et une partie de décharge reliée à l'extrémité de la partie d'application de champ magnétique dans le corps de partie de décharge à former au niveau de l'extrémité inférieure du corps de partie de décharge et évacuant le matériau fondu. 본 발명은 자화 방향이 일방향으로 배향된 자성을 가지는 3차원 조형물을 제작할 수 있는 노즐 조립체와, 이를 포함하는 3차원 프린터 및 3차원 프린팅 방법, 이를 이용하여 제조되는 전자 부품 케이스에 관한 것으로서, 토출부 바디와, 상기 토출부 바디의 상단부에 형성되어, 재료 공급 장치로부터 공급되는 재료를 송급하는 재료 송급부와, 상기 토출부 바디에서 상기 재료 송급부의 단부와 연결되어, 상기 재료 송급부를 통해 송급되는 상기 재료를 용융시키는 재료 용융부와, 상기 토출부 바디에서 상기 재료 용융부의 단부와 연결되어, 상기 재료에 포함된 금속분말이 자화될 수 있도록, 용융된 상기 재료에 자기장을 인가하는 자기장 인가부 및 상기 토출부 바디의 하단부에 형성될 수 있도록 상기 토출부 바디에서 상기 자기장 인가부의 단부와 연결되어, 용융된 상기 재료를 토출하는 토출부를 포함할 수 있다.
