Abstract :This study investigates the influence of triacrylate monomer structure on volume shrinkage, tensile properties, and viscosity of vat polymerization insert ignore into journalissuearticles values(VP); resins. The amount of triacrylate monomer kept constant as 20%wt. to prevent excessive volume shrinkage effect. Results indicated that ethoxylated and propoxylated triacrylate structures are beneficial to reduce the volume shrinkage of VP resins. However, these flexible chain structures led to a reduction in tensile properties and the elastic modulus of VP resins deteriorated up to 35% compared to trimethylolpropane triacrylate insert ignore into journalissuearticles values(TMPTA);. There is no significant effect observed on VP resin reactivity according to the triacrylate type. Besides, ethoxylated triacrylate presented the best dilution effect on VP resin.
