“…Also, there is an apparent step effect when thicker layers are used for printing [84]. Wang et al [109] predicted surface roughness of PEEK by developing a model. They found that there was a good agreement between the experimental and the predicted surface roughness and finally recommended a layer thickness of 0.15 mm for 3D printing of PEEK.…”

“…In terms of surface quality, Wang et al [109] developed a model for prediction of surface roughness of PEEK parts prepared via FFF-3D printing. They hypothesised that relationship between molecular diffusion, cross-sectional shape, and heat transfer constitutes a closed-loop.…”

“…The samples printed at higher temperatures showed smoother morphology and better interfacial bonding among adjacent filaments. This originated from the fact that molecular diffusion continues for a longer time at higher bed temperatures leading to a decrease in the number and volume of voids [109]. However, comparison between bed temperature and nozzle temperature reveals that the former has a less significant effect on the surface roughness.…”

“…In terms of surface quality, an optimal speed should be used for 3D printing of PEEK. Wang et al [109] reported that a printing speed of 15 mm/s was appropriate for PEEK. The surface topography demonstrates a large difference among samples printed at different speeds (Figure 16).…”

Poly (ether ether ketone) (PEEK) is a high-performance engineering thermoplastic polymer with potential for use in a variety of metal replacement applications due to its high strength to weight ratio. This combination of properties makes it an ideal material for use in the production of bespoke replacement parts for out-of-earth manufacturing purposes, in particular on the International Space Station (ISS). Additive manufacturing (AM) may be employed for the production of these parts, as it has enabled new fabrication pathways for articles with complex design considerations. However, AM of PEEK via fused filament fabrication (FFF) encounters significant challenges, mostly stemming from the semi crystalline nature of PEEK and its associated high melting temperature. This makes PEEK highly susceptible to changes in processing conditions which leads to a large reported variation in the literature on the final performance of PEEK. This has limited the adaption of FFF printing of PEEK in space applications where quality assurance and reproducibility are paramount. In recent years, several research studies have examined the effect of printing parameters on the performance of the 3D-printed PEEK parts. The aim of the current review is to provide comprehensive information in relation to the process-structure-property relationships in FFF 3D-printing of PEEK to provide a clear baseline to the research community and assesses its potential for space applications, including out-of-earth manufacturing.

Polyaryletherketone (PAEK) is emerging as an important high‐performance polymer material in additive manufacturing (AM) benefiting from its excellent mechanical properties, good biocompatibility, and high‐temperature stability. The distinct advantages of AM facilitate the rapid development of PAEK products with complex customized structures and functionalities, thereby enhancing their applications in various fields. Herein, the recent advances on AM of high‐performance PAEKs are comprehensively reviewed, concerning the materials properties, AM processes, mechanical properties, and potential applications of additively manufactured PAEKs. To begin, an introduction to fundamentals of AM and PAEKs, as well as the advantages of AM of PAEKs is provided. Discussions are then presented on the material properties, AM processes, processing–matter coupling mechanism, thermal conductivity, crystallization characteristics, and microstructures of AM‐processed PAEKs. Thereafter, the mechanical properties and anisotropy of additively manufactured PAEKs are discussed in depth. Their representative applications in biomedical, aerospace, electronics, and other fields are systematically presented. Finally, current challenges and possible solutions are discussed for the future development of high‐performance AM polymers.
