        Ceramic ink-jet printing has become a widespread technology in ceramic tile and ceramicware industries, due to its capability of manufacturing products on demand with various designs. Generally, thermally stable ceramic inks of digital primary colors(cyan, magenta, yellow, black) are required for ink-jet printing of full color image on ceramic tile. Here, we synthesized an aqueous glass-ceramic ink, which is free of Volatile organic compound(VOC) evolution, and investigated its inkjet printability. CoAl2O4 inorganic pigment and glass frit were dispersed in aqueous solution, and rheological behavior was optimized. The formulated glass-ceramic ink was suitably jetted as single sphere-shaped droplets without satellite drops. After ink-jet printing and firing processes, the printed glass-ceramic ink pattern on glazed ceramic tile was stably maintained without ink spreading phenomena and showed an improved scratch resistance.

        본 연구는 건설 디지털 제조를 위한 3D 프린팅 기술 개발을 위하여, 플라이애시 및 고로슬래그 미분말 등의 알칼리 활성화 결합재를 Binder Jetting 3D 프린팅 방식으로 출력하고, 후처리 방법을 통해 출력물의 압축강도를 증진하는 것이다. 진공 펌프 및 규산나트륨-수산화나트륨 복합 수용액을 적용하여 후처리 방법을 검토하였으며, 후처리 용액에 침지한 후 -0.1 MPa 진공 압력으로 처리한 공시체의 압축강도는 11.04 MPa 로써 강도 증진을 확인하였다.
