Abstract

<div class="section abstract"><div class="htmlview paragraph">As additive manufacturing continues to establish its position within the automotive sector, there is a need for a comprehensive exploration of the mechanical attributes exhibited by locally sourced filaments. Such investigation is extremely important, as it is intrinsically linked to ensuring the reliability and security of components manufactured through 3D printing. This research delves into an examination of the impact resistance properties demonstrated by 3D-printed specimens, employing filaments from three prominent Brazilian manufacturers. The main objective is to elucidate the suitability and potential applications of these filament materials (Polylactic Acid (PLA), Polyethylene Terephthalate Glycol (PETG), and Acrylonitrile Butadiene Styrene (ABS)) within the field of automotive engineering, thus contributing to the evolving landscape of additive manufacturing within this industry. This investigation encompasses the production of test specimens utilizing individual filaments into two distinct printing orientations (0°/90°), intended to mimic real-world scenarios commonly found on automotive components. Subsequently, we subject these specimens to standardized Izod impact tests conducted under carefully controlled temperature and humidity conditions. By analyzing the results, this research provides practical insights into the suitability of PLA, PETG, and ABS filaments for automotive 3D printing. This information will aid automotive engineers and manufacturers in selecting the most suitable filament material and print orientation to optimize the impact resistance of 3D printed parts, thus enhancing vehicle safety and longevity. This work contributes to the field of automotive engineering and additive manufacturing by addressing the specific needs of the market and showcasing the potential of locally sourced filament materials for creating robust 3D printed components in the automotive sector.</div></div>
