Abstract: Stereolithography 3D printing technology has broad application prospects in the preparation of special-shaped piezoelectric ceramics. In this paper, barium titanate (BaTiO3) piezoelectric ceramics were prepared by digital light processing technology. The effects of green body morphology and sintering temperature on the microstructure of barium titanate were studied. The results show that the introduction of Triton X-100 makes the viscosity of ceramic slurry less than 3 Pa·s, and the introduction of ceramic powder does not change the properties of resin. The bonding between the layers of ceramic green body is good, and there are no obvious defects. The BaTiO3 ceramics after sintering contains tetragonal and orthorhombic phases. The remanent polarization is 27.6 μC/cm2, the coercive field is 4.6 kV/cm, the relative dielectric constant is 2 512, the dielectric loss is 0.009 1, the Curie temperature is 167 ℃, and the dielectric constant is 182 pC/N.

Key words: barium titanate, piezoelectric ceramics, digital light processing technology, additive manufacturing, ferroelectric property, dielectric property
