Abstract Photopolymerization‐based ceramic 3D printing, known as digital light processing (DLP), offers a valuable platform for rapidly prototyping previously unattainable intricate architectures without the need additional molds. However, presence of particles in photocurable suspensions introduces challenges, including elevated viscosity and diminished curing depth due to light‐ceramic particle interactions. This ultimately compromises efficacy photocuring process, resulting undesirable geometric inaccuracies. In this study, meticulously engineered lead‐free ferroelectric barium titanate (BaTiO 3 , BTO) granules, produced through spray‐drying optimize suspension formulation. approach enhances flowability involves judicious addition binder, yielding uniform redispersion within matrix, while maintaining bimodal size distribution with reduced diameters. Supported by both experimental numerical simulations, improves rheological properties, enabling successful fabrication highly dense, complex 3D‐printed BTO structures excellent shape fidelity. Moreover, carefully designing thermal profiles, DLP ceramics exhibit impressive retention after debinding sintering demonstrating dielectric performances comparable their non‐3D‐printed counterparts. study presents transformative that unlocks full potential printing.
