As the choice of additive manufacturing (AM) technologies is becoming wider with reliable processes and a range materials, selection right technology to fabricate certain product increasingly difficult from technical cost perspective. In this study polyether-ether-ketone cranial implants were manufactured by two AM techniques: powder bed fusion (PBF) fused filament fabrication (FFF) their dimen...

Functionally Graded Materials represent the next generation of engineering design for metal and plastic components. In this research, a specifically modified optimised 3D printer was used to manufacture functionally graded polyether ether ketone This paper details manufacturing methodologies in development capable producing materials through manipulation microstructure. The interaction individu...

Total limb amputation is quite common in small animals, although most of the indicated pathologies do not need such a restrictive procedure. Exo-endoprosthesis suggested alternative for enhancement biomechanical situation these patients. 3D printing internal part exo-endoprostheses polyether ether ketone (PEEK) evaluated. Two different shapes this part—one radius’ and other cylindrical medullar...

High strain loading response of high-performance aerospace grade polyether-ether-ketone (PEEK) and toughened epoxy carbon fibre-reinforced composites has been investigated in pre-impregnated laminates having identical fibre volume fraction, i.e. nearly 65%. Tensile cyclic tests have carried out on the with [±45°]8S stacking sequence, order to characterise inelastic (plasticity) parameters for t...

Abstract The ability of atomistic and coarse-grained models to discern between two polymers very similar architecture is examined. To this end, polyether ether ketone (PEEK) (PEKK) are chosen. difference in glass transition temperature the similarity compressive responses captured by all-atom models. A coarse-graining scheme, with 6 beads per monomer 3 types beads, leads a good approximation st...

Polyether ether ketone (PEEK) is a biocompatible alternative to metallic biomaterials because of its unique properties and biocompatibility. Its bioinert nature may lead implant failure from inadequate osseointegration. Therefore, this research aims develop the nSiO2 ceramic particle-reinforced PEEK (nSiO2@PEEK) polymer nanocomposite. The particle size nanoparticles was measured as 43.6 nm usin...
