| Abstract Scope |
Additive manufacturing advancements enable complex structures using diverse materials. New equipment handles high-melting-point thermoplastics like PolyEtherKetoneKetone (PEKK), a promising thermoplastic polymer for 3D printing. However, challenges remain in optimizing PEKK's printability. This study investigates the effect of Fused Deposition Modeling FDM parameters on PEKK's tensile strength. After evaluating the crystallization kinetic amorphous nature of PEKK filament through Differential Scanning Calorimetry (DSC) and its thermal degradation limits through Thermogravimetric Analysis (TGA), we analyze structural and thermal processing factors through various trials. Our results compare raw PEKK filament properties with those of FDM-printed samples, demonstrating the influence of both thermal and print pathway parameters on tailoring mechanical properties for specific applications. These parameters affected the strength and toughness of the 3D-printed parts and the results were later justified through microscopic imaging, verifying the void geometry and size, presence of bubbles, and fracture surface evaluation as a backbone for this study. This characterization paves the way for further studies on optimizing PEKK's printability for high-performance applications. |
