We have demonstrated successful 3D printing of 8 mol % yttria stabilized zirconia. YSZ powders of varying sizes were acquired from commercial suppliers. Particle size, surface area, composition, and particle imaging were completed to characterize each powder before slurry preparation. Particles with surface area of 8 m2/g provided ideal solids loading in slurries. Our target was printing with 50% solid loading using CeraFab-8500. Sample disk were printed and sintered. Scanning electron microscopy and energy dispersive spectrometry were used to record microstructure and chemical speciation in these ceramics. Temperature controlled electrical conductivity was measured using appropriate electrode. These results were compared to samples of traditionally pressed ceramics to determine the effects 3D printing has on conductivity and strength of green and sintered ceramics. Areas of focus are the effects layering may have on structure and conductivity as well as the effects the addition of photosensitive polymers has on sintered ceramics density.
