Zusammenfassung:	The present invention relates to a 3D printer cartridge and a 3D printer, wherein a cartridge filled with a liquid material is used to prevent the degradation of the liquid material, and a 3D structure can be manufactured without contamination. To this end, the 3D printer according to the present invention comprises: a liquid material supply unit provided with an ejection hole, for ejecting the liquid material upward, and a storage part, which is connected to the ejection hole and in which the ejected liquid material is stored; a liquid layer-forming unit that moves the liquid material, stored in the storage part, to a work holder, which is a region irradiated with a shaping beam, and forms a liquid layer for 3-dimensional shaping; and a 3-dimensional shaping unit which performs 3-dimensional shaping by irradiating, with the shaping beam, the liquid layer formed on the work holder.
