This thesis explores Fused Deposition Modeling (FDM) technology within the framework of Additive Manufacturing, beginning with an overview of its fundamental operating principles and an analytical discussion of its inherent criticalities. The investigation proceeds with an experimental phase, involving the mechanical characterization of two different materials: PLA and PLA-CF (Carbon Fiber reinforced PLA). Through tensile and flexural testing, the study evaluates how printing parameters and material composition influence structural performance. To achieve a high level of precision in the analysis, Digital Image Correlation (DIC) is employed to map strain distributions and monitor deformation patterns in real-time. The results provide a comparative assessment of the mechanical properties, highlighting the effects of fiber reinforcement on the strength and stiffness of the printed components.
L'elaborato si propone di esplorare la tecnologia Fused Deposition Modeling (FDM) nel contesto dell' Additive Manufacturing, partendo da un'esposizione iniziale sui suoi principi di funzionamento e dalla discussione analitica delle criticità a cui è soggetta. L'indagine prosegue poi con un approccio sperimentale dove tali problematiche sono indagate attraverso prove di trazione e flessione su due materiali diversi: PLA e PLA rinforzato con fibre di carbonio (PLA-CF). I risultati delle analisi numeriche e sperimentali saranno integrate dall'impiego della Digital Image Correlation (DIC), consentendo una mappatura accurata dei campi di deformazione e una migliore interpretazione visiva dei fenomeni meccanici indagati.

Abstract
This thesis explores Fused Deposition Modeling (FDM) technology within the framework of Additive Manufacturing, beginning with an overview of its fundamental operating principles and an analytical discussion of its inherent criticalities. The investigation proceeds with an experimental phase, involving the mechanical characterization of two different materials: PLA and PLA-CF (Carbon Fiber reinforced PLA). Through tensile and flexural testing, the study evaluates how printing parameters and material composition influence structural performance. To achieve a high level of precision in the analysis, Digital Image Correlation (DIC) is employed to map strain distributions and monitor deformation patterns in real-time. The results provide a comparative assessment of the mechanical properties, highlighting the effects of fiber reinforcement on the strength and stiffness of the printed components.| File | Dimensione | Formato | |
