摘要：
This study demonstrates the feasibility of fabricating by additive manufacturing composite objects based on acrylic hybrid photocurable formulations, containing 45% by weight of silica nanoparticles, with an average size of about 30 nm. A commercial stereolithography apparatus was used to selectively cure, layer by layer, the high-loaded acrylic resin. The presence of the filler determines an increase in the physical and mechanical properties of the samples that become significantly stiffer and stronger than the pristine matrix. Dynamic mechanical analysis performed on the printed samples gave promising results for the use of developed formulation in the realization of three-dimensional (3D) polymeric structures with improved mechanical properties. © 2021 John Wiley & Sons, Ltd.
