Three‐dimensional complex construct fabrication of illite by digital light processing‐based additive manufacturing technology

Illite is a group of clay minerals that are expected to be widely used in catalyst fabrication, radioactive element adsorption, and so forth, due its excellent adsorption properties. However, the shape control limitation illite product should overcome maximize utilization We herein propose additive manufacturing (AM) as one best solutions solve this structural drawback. Digital light processing (DLP) technology with film-type material supplying system was adapted instead general vat-type DLP increase printability. The photo-curability printability illite-contained photocurable suspension were optimized. color effect different ferric oxide content yellow- white-illite which influence photopolymerization process also adjusted thoroughly. White showed better could increased solid loading than yellow illite. defect-free products three-dimensional complex structures, cannot produced by typical ceramic processes, obtained for both after sintering at 1100°C. overcoming illites AM proved study has potential expanding utilities various applications.
