The present invention relates to a heating element composition capable of three-dimensional molding. Specifically, the present invention has high elongation properties and has excellent high-temperature durability, which is a trade-off between elongation properties, so mechanical damage such as cracks can be suppressed during stretching, unlike conventional stretchable materials. The heating element composition does not return to the original shape after molding, but has the characteristic of stably maintaining the molded shape, and the rate of change in resistance can be minimized when deformed by three-dimensional molding. The heating element composition can be cured at 150℃ or lower and can be formed into a heating element through various printing or coatings, allowing three-dimensional molding applicable to various film heaters. 본 발명은 3차원 성형이 가능한 발열체 조성물에 관한 것이다. 구체적으로, 본 발명은 고연신성을 보유하는 동시에 연신성과 상충관계에 있는 고온 내구성이 우수하여 연신시 크랙 등의 기계적 파손이 억제될 수 있고, 종래 스트레처블 소재와 같이 성형 이후 원래의 형상으로 복원되는 것이 아니라 성형된 형상으로 안정적으로 유지되는 특성을 보유하며, 3차원 성형에 의한 변형시 저항의 변화율이 최소화될 수 있고, 150℃ 이하에서 경화 가능하고 다양한 인쇄나 코팅에 의해 발열체를 형성할 수 있어 다양한 필름 히터에 적용 가능한 3차원 성형이 가능한 발열체 조성물에 관한 것이다.
