The present invention provides a composition for photo-sintering capable of three-dimensional printing. By providing the composition comprising flake and non-flake type particles capable of controlling a light absorption rate during rapid light firing, a sintering thickness can be drastically increased and high conductivity can be secured. 본 발명에서는 급속광소성시 광흡수율을 제어할 수 있는 플레이크 및 비플레이크형 입자를 포함하는 조성물을 제공함으로서, 소결두께가 비약적으로 증가하는 동시에 고전도성을 확보할 수 있는 3차원 인쇄가 가능한 광소결용 조성물을 제공한다.
