Introductory Analysis for Fatigue Testing of MEX Parts

The paper discusses the use of 3D printing technology in the production of machine parts and the impact of production parameters on load-bearing capacity. Numerical simulations and stochastic theories are used to determine the effects of cyclic external loading conditions, which are typical in the vehicle industry. However, these numerical simulations must have many material property parameters. The study focuses on the material characteristics of Material Extruded (MEX) polymers, specifically PLA, and the impact of production direction and manufacturing parameters on the material's properties. The paper concludes that further investigation is necessary to determine specimens' dynamic load-bearing capacity and understand orthotropic materials' behavior.
