Digital light processing (DLP) is a high-speed, high-precision 3-dimensional (3D) printing technique gaining traction in the fabrication of ceramic composites. However, when 0-3 composites containing lead zirconate titanate (PZT) particles, widely used piezoelectric ceramic, severe density and refractive index mismatches between 2 phases pose challenges for ink synthesis process. Here, we systematically quantitatively optimized DLP PZT composites, streamlining process development providing solid theoretical experimental foundation broader applications technology. particles were pretreated with air plasma to improve slurry uniformity enhance stress transfer at composite interface, leading improved chemical modification, mechanical strength, properties. We investigated effects key parameters on printability accuracy by analyzing curing behavior PZT–polymer A quantitative model was introduced. Unlike stereolithography (SLA), depth found depend energy dose intensity, higher intensities proving more favorable From depth/width–energy curves, optimal determined. designed fabricated soft metamaterial-based touch sensor using these parameters, achieving customized output profile. This work offers critical insights into optimizing functional materials expands potential 3D-printed
