The present invention relates to a 3D printer and a disposable film used therein, the 3D printer being capable of preventing deterioration of liquid materials by using cartridges filled with liquid materials and allowing a three-dimensional (3D) sculpture to be produced without contamination, wherein occurrence of contamination by liquid materials around a work holder where the 3D sculpture is produced can be prevented. To this end, the disposable film of the present invention used for a 3D printer, which can be mounted on a 3D printer that comprises a work holder capable of being raised and lowered step by step by means of an up-and-down drive unit and that forms a 3D sculpture by stacking each layer of the 3D sculpture on top of the work holder while lowering the work holder step by step, comprises: a square-shaped base film; and side films connected to both sides of the base film, wherein the base film can be mounted on the base surface of the work holder, in which a base negative pressure hole is formed to enable a negative pressure action, and the side films can be mounted on side surfaces of the work holder. La présente invention se rapporte à une imprimante 3D et à un film jetable utilisé dans cette dernière, l'imprimante 3D étant apte à empêcher la détérioration de matériaux liquides à l'aide de cartouches remplies de matériaux liquides et permettant à une sculpture tridimensionnelle (3D) d'être produite sans contamination, l'apparition d'une contamination par des matériaux liquides autour d'un support de travail où la sculpture 3D est produite pouvant être empêchée. À cet effet, le film jetable de la présente invention utilisé pour une imprimante 3D, qui peut être monté sur une imprimante 3D qui comprend un support de travail pouvant être soulevé et abaissé pas à pas au moyen d'une unité d'entraînement vers le haut et vers le bas et qui forme une sculpture 3D par empilement de chaque couche de la sculpture 3D sur le dessus du support de travail tout en abaissant le support de travail pas à pas, comprend : un film de base de forme carrée ; et des films latéraux reliés aux deux côtés du film de base, le film de base pouvant être monté sur la surface de base du support de travail, dans lequel un trou de pression négative de base est formé pour permettre une action de pression négative, et les films latéraux pouvant être montés sur des surfaces latérales du support de travail. 본 발명은 액상재료가 충전된 카트리지를 이용하여 액상재료의 변질을 방지하고, 오염이 없이 3차원 구조물을 제작할 수 있도록 하는 3D 프린터에 있어 3차원 조형물이 제작되는 워크홀더 주변에 액상재료에 의한 오염이 발생하는 것을 방지할 수 있도록 하는 3D 프린터 및 이에 사용되는 일회용 필름에 관한 것이다. 이를 위한 본 발명의 3D 프린터에 사용되는 일회용 필름은, 상하구동유닛에 의해 단계적으로 승하강이 가능한 워크홀더를 포함하여 구성되고, 상기 워크홀더를 단계적으로 하강시키면서 3차원 조형물의 각 층을 상기 워크홀더의 상부에 적층하여 3차원 조형물을 조형하는 3D 프린터에 장착이 가능한 일회용 필름으로서, 사각 형상의 베이스필름; 및 상기 베이스필름의 양측에 연결된 측면필름;을 포함하여 구성되고, 베이스 음압홀이 형성되어 음압 작용이 가능한 상기 워크홀더의 베이스면에 상기 베이스필림이 장착가능하고, 상기 워크홀더의 측면에 상기 측면필름이 장착 가능한 것을 특징으로 한다.
