Impact Loading Characteristic of SLA 3D-Printed Nano-Silica Reinforced Photopolymer

Year: 2026

Type: article

Abstract: Additive manufacturing continues to expand across multiple industries, driving the need for enhanced photopolymer materials capable of resisting dynamic and impact loading. In this study, a commercially available stereolithography (SLA) resin was reinforced with 0.1, 0.3, and 0.5 wt.% nano-silica, fabricated via SLA 3D printing, post-cured, and evaluated using notched Izod impact testing (ASTM D256). The results show a progressive increase in impact resistance with nano-silica content, with the 0.5 wt.% nanocomposite exhibiting the highest absorbed impact energy compared to the unreinforced resin. These findings demonstrate that low loading nano-silica reinforcement is an effective strategy for improving the impact resistance of SLA-printed photopolymers under high strain-rate loading conditions, rather than enhancing quasi-static tensile behavior.
