Investigation of experimental analysis of fabricating lattice structures through 3D printing (Liquid SLA): The case of porous engineered structures subjected to impact loading

The primary objective of this study is to evaluate and contrast the impact strength of liquid laminate reinforced composites that were manufactured through the use of stereolithography with those that were manufactured using silica nanoparticles as a filler on the surface of indentation operations. A Brief History and the Procedures: The impact strength of two sets of stereolithography liquid sample specimens was evaluated in this study. One group had filler, and the other group did not contain any filler. Twenty specimens made comprised the control group, whereas twenty specimens that did not include any filler were included in the experimental group. For the purpose of determining the sample size, the G Power is established at 80 percent, with α having a value of 0.05 for each set. Additionally, a total of forty samples are utilised. Epoxy resin LY556 and hardener HY951 are the major components that make up this formulation. Innovating silica nanoparticles are the components that make up the filler ingredient. The assumption is that the G power is eighty percent. According to the findings, stereolithography liquid laminate composites that contain a filler consisting of new silica nanoparticles at a volume fraction of two percent appear to have smaller impact strengths in indentation testing compared to those that have no filler at all. The findings of the study demonstrated that the two groups exhibited a statistically significant difference from one another, as evidenced by a p-value of 0.000 (p
