Usage of Poly-Ether-Ether-Ketone Polymer for the Biomedical Application—A Critical Review

Fast growing applications of 3D printing still lacked with a hurdle of printing high functional executing polymers. Poly-ether-ether-ketone (PEEK) produces excellent mechanical properties, chemical stability, biological stability and biocompatibility, especially employable for clinical applications. Previous literature is on fabrication of biomedical polymers by additive manufacturing (AM) such as poly-carpolactone, poly-lactic acid, poly-glycolic acid, poly-ethylene and polyurethanes. Only few studies are conducted on 3D printing of PEEK is due to its high melting point, non-availability of feed stock and poor properties of printed parts. This present review paper concentrates on printing of porous architecture which will be suitable for various medical applications with the use of the PEEK material.
