Digital light processing (DLP) is an attractive additive manufacturing technique due to its ability to create ceramic parts with complex geometries. DLP uses ultraviolet light to polymerize a slurry comprised of ceramic powder and photosensitive resin in layers to create solid parts. Printing parameters such as light intensity and exposure time are critical when producing these parts. Improper parameters can lead to over or under-curing, adversely impacting print quality and strength. Samples were printed at varying layer exposure times and then tested using ultrasonics to determine the degree of conversion. Additionally, ultrasonics were used as a non-destructive technique to obtain the elastic modulus of the manufactured composites. The aim of this research was to investigate the effect of printing parameters on the ultrasonic response of polymer-ceramic composite parts and to establish a non-destructive method that incorporates ultrasonic techniques to evaluate mechanical properties to assure print quality.
