- Аннотация: The additive manufacturing of BaTiO3 (BT) ceramics through stereolithography (SLA) 3Dprinting at 465 nm wavelength was demonstrated. After different milling times, different paste compositions with varied initial micron-sized powders were studied to find a composition suitable for3D printing. The pastes were evaluated in terms of photopolymerization depth depending on thelaser scanning speed. Furthermore, the microstructure and properties of the BT ceramic samplesproduced through SLA 3D printing were characterized and compared with those of ceramics fabricated through a conventional die semi-drying pressing method. Three-dimensional printed samplesachieved relative densities over 0.95 and microhardness over 500 HV after sintering, nearly matching the relative density and microhardness attained by the pressed samples. Upon poling, the 3Dprinted samples attained acceptable piezoelectric module d33 = 148 pC/N and dielectric constantsover 2000. At near full density, BT piezoceramics were successfully fabricated through SLA 3Dprinting at 465 nm wavelength, achieving photopolymerization depth of more than 100 microns.This work paves the relatively low-cost way for 3D printing of piezoelectric ceramics using conventional micron-sized powders and high printed layer thickness.
