Preparation and characterization of barium titanate suspensions for stereolithography
Ferroelectric photoactive suspensions for stereolithography have been developed by dispersing a high volume fraction of barium titanate ponder in hexanediol diacrylate (HDDA) with the aid of effective photoinitiators and dispersants, Rheological properties showed a shear thinning behavior and a tom viscosity at a shear rate adequate for the recoating process. The barium titanate-HDDA suspension showed poor curing behavior due to the targe refractive index difference between the ceramic and the resin. The coarse barium titanate-HDDA suspension showed a smaller surface reflectance and a larger cure depth than the fine barium titanate-HDDA suspension.
