Abstract

<jats:p>&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;This article explores the impact of As-built versus annealed Fused DepositionModeling (FDM) on the mechanical properties of test samples fabricated from twodistinct materials: Polyamide 6 (PA6) and PA6 with carbon fiber filament.Employing the FDM technique, these samples were meticulously produced, withsignificant process parameters maintained at optimal values. Two sets of printedspecimens were prepared for examination, one composed of PA6 and the other ofPA6 with carbon fiber (CF) reinforcement. The first set was subjected tomechanical testing in its As-built condition, while the second set underwent anannealing process utilizing a muffle furnace. The annealing reduces internalstresses, enhances interlayer adhesion, and promotes crystallinity. For both thesent samples exposed to comprehensive assessments to evaluate various mechanicalperformance attributes, including hardness, impact strength, tensile strengthand flexural strength. The results of this study elucidate that PA6 with carbonfiber exhibited superior mechanical properties than PA6. In further, this studyoffers valuable insights into the influence of FDM post-processing techniques,such as annealing, on the mechanical behavior of printed components. In FDMAnnealed PA6 with carbon fiber emerged as the combination with the most superiormechanical properties across hardness, impact strength, and tensile strength.This study underscores the significance of carbon fiber reinforcement andannealing in enhancing the mechanical performance of PA6 components, providingvaluable insights for applications demanding robust mechanical properties.&lt;/div&gt;&lt;/div&gt;</jats:p>
