“…Such results are in agreement with the work of Seong-Hun et al [ 32 ], who analyzed the MFR of pure PET-G compared to PET-G/TiO 2 composite and found no significant difference between the values of the samples. Car et al [ 33 ] determined the MFR of Z-GLASS material (based on PET-G) and its composite with TiO 2 filler and found an increase in the MFR value with increasing filler content, similar to the MFR value increase with the lower filler content of this work. This increase in the MFR values or decrease in the viscosity is not necessarily filler-dependent, but can be explained by the theory of polymer chain length scission due to degradation during thermal processing, as shown by Colin et al [ 34 ].…”

“…Additionally, possible inhomogeneity and possibly trapped air bubbles in the material are all locations of stress concentration which can cause premature yield of the composite material. The work by Car et al [ 33 ] mentions problems with inhomogeneity and entrapped air bubbles when TiO 2 filler is mixed into the polymer (Z-GLASS, PET-G-based material) matrix and preforming a tensile test. These problems greatly affected the results, but ultimately, the conclusion was also that the further increase in filler content led to the decrease in mechanical properties.…”

This paper investigates the possibility of integrating the combination of nanofillers, titanium dioxide (TiO2) and carbon nanotubes (CNT) into the thermoplastic polymer matrix. This combination of fillers can possibly modify the physico-chemical properties of composites compared to the pure polymer matrix. The composites were blended using the extrusion method. The composite filament produced was used to manufacture static mixers on a 3D printer using the additive manufacturing technology fused filament fabrication (FFF). The aim of this work was to inspect the influence of the filler addition on the thermal and mechanical properties of glycol-modified polyethylene terephthalate (PET-G) polymer composites. The fillers were added to the PET-G polymer matrix in several ratios. Tensile test results showed an increase in the overall strength and decrease in the elongation at break of the material. Melt flow rate (MFR) showed a decrease in the viscosity with the initial filler addition and reaching a plateau after 2 wt% filler was added. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) showed minor changes in the thermal properties. Scanning electron microscope (SEM) results showed homogenous distribution of the filler in the matrix and strong filler–matrix adhesion. The results indicate suitable properties of new functional composites for the 3D printing of static mixers for application in tubular reactors.

“…FFF has been proven to have several advantages, including ease of use, cost-effectiveness, customization capabilities, the ability to create filled polymer composites, and the production of multifunctional parts with complex geometries using conventional techniques. , Although it has many advantages, FFF does have certain limitations, such as surface finishing issues and the “staircase effect” caused by overlapping material layers, resulting in rough surfaces on the printed models. Another limitation is the lack of temperature control during extrusion, leading to decreased accuracy and a higher likelihood of wrapping. , …”

The development of shape-optimized adsorbent materials has garnered significant scientific interest in light of escalating environmental challenges and limitations of conventional materials. Addressing the issues of single-use materials is crucial to advancing adsorbent technologies. Recently, 3D-printed zeolite-polymer composites have emerged as versatile and promising adsorbent materials, offering deployability, retrievability, thermal stability, and cyclic regeneration capabilities. The synergistic combination of zeolite-composite formulations and 3D printing technology represents a promising approach for fabricating the perfect adsorbent for water treatment. This comprehensive review critically examines recent advancements in the realm of 3D printing technology to shape zeolite–polymer composites, specifically for water treatment applications. The facile fabrication of 3D-printed zeolite structures, accomplished by shaping zeolite within an ink solution and employing a printing process, enables the production of materials featuring macroporous, mesoporous, and microporous systems. These advancements hold significant promise for the design and implementation of highly efficient adsorbent materials for water treatment processes.

“…Several printing techniques from the plethora of AM technologies available nowadays have been applied for printing of predominantly monolithic catalyst geometries. Direct Ink writing (DIW/robocasting) or fused deposition modeling (FDM) are extrusion-based principles and most commonly used due to their relatively intuitive material design, especially regarding processing of metal oxide feedstock [23][24][25][26][27][28]. Powder-based techniques oftentimes require more detailed material and process development.…”
