摘要

The research introduces a budget-friendly Izod impact testing system for plastic evaluation and analysis through Python. The system received validation through experiments which combined design of experiments with finite element method (FEM) simulations and statistical analysis. The research applied Python data analysis to study how 3D printing parameters, such as extrusion temperature, layer height, infill density, and geometry, affect absorbed energy and impact toughness. The Izod impact testing bench operates by converting gravitational potential energy into absorbed energy which can be measured by calculating the pendulum's initial and final heights. The HTML application, specifically designed for this purpose, analyzed the experimental measurements of impact toughness. The experimental results were analyzed through Python data analysis and FEM methodology to obtain impact test outcomes. The measured properties showed no change due to extrusion temperature, but the infill density, geometry, and layer height significantly affected printed components' energy absorption and impact toughness. The research findings confirm previous studies about how design and printing parameters influence plastic mechanical properties. The FEM analysis confirmed the experimental results which validated the developed impact testing setup for 3D printing optimization.
