Evaluation of tensile property of SiO2 dispersed SLA 3D printed epoxy composites

An experimental investigation was conducted to ascertain the impact of nanoparticles additions on the mechanical properties of SiO2/epoxy nanocomposites. The nanocomposites were synthesized via ultrasonic mixing, incorporating SiO2 nanoparticles dispersed at 0, 0.5, 1, and 1.5 wt%. Tensile samples were generated through the SLA 3D printing procedure. The results indicate that samples containing 0 wt% nanoparticles have the highest tensile stress value (40.37 Mpa), while samples containing 1 wt% nonparticipants have the lowest tensile stress value (34.71 Mpa). Tensile samples produced with a one wt% solubility dispersion of nanoparticles exhibit a maximum extension of 2.70 mm.
