“…Several studies have combined the features of PEEK and CNTs to improve the properties and functionality of manufactured parts. − Other studies focused on the thermal parameters during the processing (heat treatment, nozzle temperature, and ambient temperature) or other printing parameters (deposition pattern and thickness, infill density, and nanomaterial content) and the resulting effects on the material properties and microstructure of the printed parts. − However, there are still discrepancies between different reports and their conclusions. , This is partly due to the process-sensitive nature of semi-crystalline thermoplastics and their nanocomposites and especially true for PEEK due to its fast crystallization kinetics. There are relatively few attempts to focus on the governing phenomena occurring during the extrusion-based AM of PEEK nanocomposites.…”

As fused filament fabrication (FFF) continues to gain popularity, many studies are turning to nanomaterials or optimization of printing parameters to improve the materials’ properties; however, many overlook how materials formulation and additive manufacturing (AM) processes cooperatively engineer the evolution of properties across length scales. Evaluating the in-process evolution of the nanocomposite using AM will provide a fundamental understanding of the material’s microstructure, which can be tailored to create unique characteristics in functionality and performance. In this study, the crystallinity behavior of polyetheretherketone (PEEK) was studied in the presence of carbon nanotubes (CNTs) as a nucleation aid for improved crystallization during FFF processing. Using various characterization techniques and molecular dynamics simulations, it was discovered that the crystallization behavior of extruded filaments is very different from that of 3D printed roads. Additionally, the printed material exhibited cold crystallization, and the CNT addition increased the crystallization of printed roads, which were amorphous without CNT addition. Tensile strength and modulus were increased by as much as 42 and 51%, respectively, due to higher crystallinity during printing. Detailed knowledge on the morphology of PEEK–CNT used in FFF allows gaining a fundamental understanding of the morphological evolution occurring during the AM process that in turn enables formulating materials for the AM process to achieve tailored mechanical and functional properties, such as crystallinity or conductivity.

“…It has good high-temperature resistance, fatigue resistance, high strength and corrosion resistance. It has been widely used in aerospace, automobile and other fields [1][2][3][4][5][6][7][8][9]. The advantage of additive manufacturing (AM) technology is that it can quickly manufacture parts with complex structures and individual structures and has high material utilization [10].…”

In this study, photosensitive resin mould was made by stereolithography technology to inject individualized polyether ether ketone (PEEK) parts. In simulation experiment, the temperature field of the PEEK injection mould was analysed by finite element analysis; it was preliminarily determined that the resin mould will not be deformed during the injection process. The optimum parameters of PEEK injection process were obtained by orthogonal experiment: injection temperature 373 °C, injection pressure 11 MPa and injection speed 70%. Mechanical tests were carried out on PEEK samples injected by this process. The results showed that the average tensile strength was 96.4 ± 2.28 MPa, the average bending strength was 147.654 ± 9.36 MPa, and the impact strength was higher than 10 kJ/m 2 . The experimental results show that it is feasible to produce photosensitive resin mould to inject individualized PEEK parts by stereolithography. Photosensitive resin mould has lower cost, shorter production cycle and no waste of PEEK material during injection process. The injection method in this study greatly reduced the production cost of individualized PEEK parts and can obtain PEEK parts with good mechanical properties in a relatively fast time.

“…Composites of several different types of HPPs have been demonstrated including but not limited to PEEK, PEI, polyaryletherketone (PAEK), polyarylsulfones, and PESU. Thus far, the inclusions used in these composites have been limited to glass beads and fibers, carbon nanotubes (CNTs), CF, and various inorganic materials. − To our knowledge, there are no commercial sources for HPP composites that are 3D-printable, and as such the composites must be synthesized before printing. The most common printing technique used for these materials is MME.…”

100th Anniversary of Macromolecular Science Viewpoint: Integrating Chemistry and Engineering to Enable Additive Manufacturing with High-Performance Polymers

Additive manufacturing (AM) with high-performance polymers (HPPs) represents simultaneously one of the most desirable and challenging feats in the AM arena. The very properties that make HPPs so attractive in a broad range of applications also make them nearly impossible to process using common AM equipment. Furthermore, when AM is achieved, it often brings the caveat of compromised mechanical properties of the final parts, in comparison with those made via injection molding. The demand to have advanced fabrication methods, rapid prototyping, and customization of parts while maintaining high performance in the finished products has inspired creative innovations that integrate chemical synthesis, materials science, mechanical engineering, and other fields into a multidisciplinary approach to advance AM with the seemingly "unprintable" HPPs. In this Viewpoint, we summarize several standout developments in the area and offer our perspective on future directions and challenges.
