A systematic review of the process parameters, mechanical characteristics and applications of polyether ether ketone (PEEK) and its composites by additive manufacturing

Additive manufacturing (AM) provides an innovative and reliable method of developing medical products with anatomically relevant geometry and mechanical performance, underscoring its significant potential in the medical field. The design of fused deposition modelling (FDM) parameters has a significant impact on the characteristics of the product fabricated utilizing FDM. Numerous studies have assessed the impact of various FDM process parameters on enhancing the print quality attributes of manufactured components, such as mechanical characteristics, production times, dimensional accuracy, and surface finish. Because of the complex features of the FDM process and the contradicting process parameters, the advancement has been slow and poorly coordinated. This work intends to provide a complete review of recent research on PEEK and CF-PEEK printed parts, where the effect of process factors on tensile strength has been described. Furthermore, PEEK, with its potential applications in medical, aerospace, and chemical sectors, serves as an inspiring material for future innovations, offering a promising outlook.
