ABSTRACT

This research investigates the mechanical properties of 3D printed polymers, with materials extracted from natural fibers and petroleum sources, such as PLA, PETG, PLA with bamboo fibers, PLA with carbon fibers, and nylon. Mechanical tests—including tensile, impact (Izod), flexural, and hardness tests—were conducted following ISO standards to evaluate the performance, strength, and durability of these materials. These tests provide essential data on how each polymer responds to stress, impact, bending, and surface deformation. The study aims to understand how variations in material composition and processing conditions affect mechanical behavior. By analyzing differences in tensile strength, impact resistance, flexibility, and hardness, the research highlights the influence of different formulations on material performance. The insights gained are crucial for selecting suitable materials for a range of applications, from industrial components to consumer products and specialized uses. This thorough evaluation supports informed decision-making in 3D printing, enhancing the technology’s effectiveness and fostering innovation in material performance and application.
