“…In the special case of PEEK printing with FDM, the not highly related parameters are either not involved, such as power characteristics and binder characteristics, or of secondary priority for small parts, such as fill pattern and support structure. Methods for the characterization of printed PEEK samples are mainly scanning electron microscope (SEM) [15,22,23], 3D scanner [15], differential scanning calorimetry (DSC) [13], and water contact angle measurements [23]. These methods mainly assess the dimensional accuracy, surface roughness, microstructure of interface, and crystalline ratio of printed PEEK objects.…”

“…If the nozzle temperature is too high, chain cleavage might occur and possibly leading to decomposition [15]. Nozzle temperatures have been explored within a range from 340 • C to 480 • C [13,[15][16][17][18][20][21][22][23]. Wu et al [15] found when the nozzle temperature is 350 • C, the warping deformation of PEEK samples is minimal.…”

“…If the extrusion speed does not match with the printing speed, there will be extra material sticking to the nozzle causing unstable dimensions of the printed specimens. Geng et al [22] investigated the effects of the extrusion and printing speed on the microstructure and dimensions of an extruded PEEK filament. They performed the experiments with nozzle diameters of 0.4, 0.5, and 0.6 mm and printing speeds from 0.1 to 120 mm/min.…”

In this review, we discuss the parameters of fused deposition modeling (FDM) technology used in finished parts made from polyether ether ketone (PEEK) and also the possibility of printing small PEEK parts. The published articles reporting on 3D printed PEEK implants were obtained using PubMed and search engines such as Google Scholar including references cited therein. The results indicate that although many have been experiments conducted on PEEK 3D printing, the consensus on a suitable printing parameter combination has not been reached and optimized parameters for printing worth pursuing. The printing of reproducible tiny-sized PEEK parts with high accuracy has proved to be possible in our experiments. Understanding the relationships among material properties, design parameters, and the ultimate performance of finished objects will be the basis for further improvement of the quality of 3D printed medical devices based on PEEK and to expand the polymers applications.

“…All these problems lead to a mechanical anisotropy and a loss of performance that are well documented in the literature . Optimization of the kinematics can help in reducing the effect of the FDM flaws such as by decreasing the layer height with respect to the nozzle diameter . One important leverage is the printing temperature, which is proved to be an efficient parameter to improve the mechanical performance of printed polymers .…”

Fused deposition modeling (FDM) is one of the most popular additive manufacturing techniques for polymers. Despite the numerous works on the printability of various types of polymers, there is a lack in understanding the role of the microstructure on the mechanical performance of printed parts. This work aims at addressing this particular point for the case of a polymer that did not receive much attention, namely acrylonitrile styrene acrylate or ASA. This study emphasizes on the effect of the printing temperature on thermal and mechanical performance of printed ASA using differential scanning calorimetry, infra‐red measurements, mechanical testing, X‐ray micro‐tomography, and finite element computation. The experimental results demonstrate a narrow window of printability of ASA based on the thermal response of this polymer during the laying down process. In addition, both experimental and numerical results show an evident loss in the performance that represents one third of the performance of the raw material. Despite this loss, the limited amount of generated porosity and the level of tensile strength of ASA make it a good choice as a feedstock material for FDM compared to other polymers such as acrylonitrile butadiene styrene.

“…They suggest using higher temperatures or less entangled materials to form thicker and more entangled welds, while the printing speed did not influence mechanical integrity in their model. 45 Geng et al 46 even found in their investigation of FDM printing polyetherether-ketone (PEEK) that higher extrusion speeds could eliminate extrusion defects and was thus preferable to gain a more compact layer surface.…”

Combining textile fabrics with three-dimensional printed items can be a good approach to save time and money as compared with purely three-dimensional printed large-scale objects, to reach desired position-dependent mechanical properties, for design and technological purposes. The main challenge in such bi-material systems is the adhesion between both partners of the composites. Although some experimental research on this topic has been performed during the last years, only few theoretical investigations exist which may support striving for material combinations with higher adhesion. Here, we give an overview of the recent state of experimental research on adhesion in textile/polymer composites as well as of theoretical investigations on adhesion inside the three-dimensional printed part. Combining both topics, we suggest further research approaches to increase the textile/polymer adhesion.
