Investigating the Impact of Fused Filament Fabrication Process Parameters on the Compressive Properties of Porous PEEK and PEKK Biomaterials

open access: yesJournal of Biomedical Materials Research Part A, Volume 114, Issue 3, March 2026.
ABSTRACT Additive manufacturing (AM) can create orthopedic devices with integrated porosity that enables bone fixation post‐implantation. While porosity is key in promoting bone ingrowth and long‐term fixation, the device must provide adequate mechanical strength and functionality. Since AM process parameters dictate the final mechanical performance of

Investigation of PEKK crystal morphology and modelling of the crystallization kinetic of PEKK composites

open access: yes, 2017
Pour les polymères thermoplastiques renforcés de fibres de carbone, le taux de cristallinité et la morphologie induite lors de la cristallisation ont un impact certain sur leurs propriétés physiques et mécaniques. Ces deux paramètres sont non seulement dépendants des conditions de mise oeuvre mais aussi des constituants du composite.
