Abstract

This study investigates the influence of triacrylate monomer structure on volume shrinkage, tensile properties, and viscosity of vat polymerization (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 (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.
