Paragraph starter

The Fused Deposition Modeling (FDM) process relies heavily on the rheological properties of thermoplastic filaments. As highlighted by Acierno and Patti (2023), understanding the viscoelastic behavior of these materials is critical for predicting printability, ensuring consistent extrusion, controlling deposition accuracy, and achieving robust layer adhesion. Therefore, material selection and process parameter optimization for FDM should be informed by an analysis of the filament's flow characteristics to achieve reliable and high-quality outcomes.
