| Abstract Scope |
Lead zirconate titanate (PZT) ceramics in thick-film or structural forms are currently in active development for various device applications. Slurry-based 3D-printing technologies, such as stereolithography (SLA) or masked stereolithography (MSLA) have come up as perspective techniques for manufacturing ceramic components because of their advantages like high resolution and reduced processing time. Ceramic ink formulations with different PZT loading (70-85 wt.%) and varying surfactant (Surfynol 420) concentration (0-4 wt.%) were prepared through acoustic mixing in the LabRAM II. The rheological characterization showed that the viscosity increased with increased PZT loading and optimized for 3 wt.% surfactant concentration. The curing study demonstrated a maximum curing depth of 135 µm for the ink with 75 wt.% PZT and 3 wt.% surfactant for an exposure time of 50 s under a 405 nm-wavelength UV source. A cube was printed successfully in a MSLA printer with the aforementioned ink formulation. |
