Abstract Polyetherketoneketone (PEKK) (60/40 TERE/ISO) is characterized by a lower processing temperature and higher glass transition (T g ) compared to polyetheretherketone (PEEK), making it promising material for 3D printing. However, remains in amorphous state post‐printing due its slow crystallization rate. In this study, isothermal annealing conducted on printed pseudo PEKK at various times temperature. Thermal analysis techniques reveal that both time play pivotal role enhancing crystallinity, with levels reaching up 27% when annealed between the T melting m ). thermal stability decreased as approached . X‐ray diffraction studies demonstrate promotes development of stable form II crystals, while temperatures encourages formation I crystals. Furthermore, dynamic mechanical indicated 44% increase stiffness following annealing, compressive testing shows improved yield strength, comparable other polyaryletherketone (PAEK) materials. These findings suggest controlled enables precise tailoring crystallinity properties, adaptable wide range applications, such biomedical devices require patient‐specific customization.

Polyether-ether-2-ketone (PEKK) is a high-performance thermoplastic polymer used in various fields, from aerospace to medical applications, due its exceptional mechanical and thermal properties. Nonetheless, the behavior of 3D-printed PEKK still deserves be more thoroughly investigated, especially view production by 3D printing, where properties measured at different scales are likely correlated one another all play major role determining biomechanical properties, which include strength on side osteointegration ability other side. This work explores through multiscale approach, having performed both nanoindentation tests standard tensile compression tests, detailed strain distribution was achieved Digital Image Correlation (DIC) techniques. Furthermore, for specimens tested up failure, their fractured surfaces were analyzed Scanning Electron Microscopy (SEM) clearly outline fracture modes. Additionally, internal structure explored Computed Tomography (CT) imaging, providing three-dimensional presence voids imperfections. Finally, surface morphology confocal microscopy. The approach adopted present offers information about global local PEKK, also assessing material down nanoscale. Due novelty as polymeric material, no previous studies have approached analysis PEKK. findings this study contribute comprehensive understanding along with criteria process optimization order customize meet specific application requirements. research not only advances knowledge 3D-printing but provides insights into multifaceted nature characterization.
