Ceramic additive manufacturing via vat photopolymerization produces a ceramic-filled, polymer matrix composite which must undergo debinding and sintering to achieve a final ceramic part. These additional steps increase the complexity of developing processing and post-processing parameters for new materials and geometries. Monolayer and bulk samples with various wall thicknesses are printed using a digital light projection system. Cure depth and degree of cure measurements are evaluated as calibration parameters for determining processing and post-processing parameters, respectively. Comparing results for two different slurries (high-purity alumina and yttria-stabilized zirconia) reveals the applicability of the method for different materials. The experiments are repeated after a routine vat upgrade in order to test sensitivity of calibration measurements to changes in the light path. This study reports the efficacy of different calibration measurements with the goal of developing a method for accelerated parameter development.
