The present invention relates to a hydrogel discharge apparatus and an operation method of the hydrogel discharge apparatus. The hydrogel discharge apparatus according to an embodiment of the present invention comprises: a capsule injection unit including an inlet into which a plurality of capsules containing a hydrogel formulation are injected, a capsule coupling unit on which the plurality of capsules injected into the inlet are seated, and a capsule part heating wire which heats bottom portions of the plurality of capsules; a formulation transfer unit including a plurality of flow paths through which the hydrogel formulation contained in the plurality of capsules is moved, a flow path heating wire which heats the plurality of flow paths, a plurality of flow path sensors which are disposed in the plurality of flow paths, and a pneumatic pressure control unit which controls a pneumatic pressure in the plurality of flow paths; a formulation injection unit including a nozzle which discharges the hydrogel formulation moved from the formulation transfer unit and a nozzle heating wire which heats the nozzle; and a formulation solidification unit including a discharge plate on which the hydrogel formulation discharged from the formulation injection unit is stacked and a discharge plate heating wire which heats the discharge plate. Therefore, the hydrogel discharge apparatus according to the present invention is capable of efficiently managing heat in the apparatus, the state of the formulation, and movement of the formulation. 상기 또는 다른 목적을 달성하기 위해 본 발명의 일 측면에 따른 하이드로겔 토출 기기는, 하이드로겔 제형을 수용하는 복수의 캡슐이 투입되는 투입구, 투입된 복수의 캡슐이 안착되는 캡슐 체결부, 복수의 캡슐 하부를 히팅(heating)하는 캡슐부 열선을 포함하는 캡슐 투입부, 복수의 캡슐에 수용된 하이드로겔 제형이 이동하는 복수의 유로, 복수의 유로를 히팅하는 유로 열선, 복수의 유로들 내부에 배치되는 복수의 유로 센서와 복수의 유로 내 공압을 조절하는 공압 조절부를 포함하는 제형 전달부, 제형 전달부로부터 이동된 하이드로겔 제형을 토출하는 노즐과 노즐을 히팅하는 노즐 열선을 포함하는 제형 분사부, 제형 분사부로부터 토출된 하이드로겔 제형이 적층되는 토출판과 토출판을 히팅하는 토출판 열선을 포함하는 제형 고형화부를 포함함으로써, 효율적으로 기기 내 열 및 제형 상태, 제형 이동을 관리할 수 있다.
