Printability and properties of PSNZT piezoelectric ceramics fabricated by DLP additive manufacturing

Achieving the synergy of low viscosity, high printing precision and enhanced curing ability for lead zirconate titanate (PZT) components is a critical issue in the field of digital light processing (DLP). Herein, the effect of calcination temperature on the morphology and grain size of PSNZT [(Pb 0 . 92 Sr 0 . 08 )(Zr 0 . 533 Ti 0 . 443 Nb 0.024 )O 3 ]ceramic powder has been investigated, and a lowest viscosity, higher printing precision and enhanced curing ability of PSNZT ceramic slurry has been achieved, resulting in a high piezoelectric constant (d 33  = 379pC/N) and a high dielectric constant (εr = 1308@100 KHz) via DLP process combined with following sintering densification (1220 °C/3 h).
