“…[ 174 ] From that, further increment of additives then leads to agglomeration of species into the composite fragment. [ 175 ] The major side effects of additive agglomeration in membranes are pore‐plugging (blockage) [ 176 ] and reduction of polymer‐additive interactions [ 177 ] which are transpired in reduction in permeability [ 178 ] and mechanical properties, [ 179 ] respectively. Number of techniques such as surface functionalization of additives [ 180,181 ] are applied to prevent the additive agglomeration into the matrix.…”

This review provides a comprehensive overview on applications, preparation methods, and most notably the performance efficiency of polyvinyl alcohol (PVA)-based membranes for filtration of aqueous environments. Incorporation of PVA into the membrane matrix significantly enhances such characteristics as antifouling and antibacterial properties as well as hydrophilicity and permeability in the water and wastewater filtrations. Contribution of different PVAbased modular membranes for water purification targets via a comparative review on previous researches is the main theme in this work. Alongside with the focused topic, some basic theories and principals of blend and composite polymer films as well as polymer fibers are debated before the main discussions. This review will ultimately facilitate further development of PVA membranes for the future investigations.

With the ability to fabricate complex structures while meeting individual needs, additive manufacturing (AM) offers unprecedented opportunities for bone tissue engineering in the biomedical field. However, traditional metal implants have many adverse effects due to their poor integration with host tissues, and therefore new material implants with porous structures are gradually being developed that are suitable for clinical medical applications. From the perspectives of additive manufacturing technology and materials, this article discusses a suitable manufacturing process for ideal materials for biological bone tissue engineering. It begins with a review of the methods and applicable materials in existing additive manufacturing technologies and their applications in biomedicine, introducing the advantages and disadvantages of various AM technologies. The properties of materials including metals and polymers, commonly used AM technologies, recent developments, and their applications in bone tissue engineering are discussed in detail and summarized. In addition, the main challenges for different metallic and polymer materials, such as biodegradability, anisotropy, growth factors to promote the osteogenic capacity, and enhancement of mechanical properties are also introduced. Finally, the development prospects for AM technologies and biomaterials in bone tissue engineering are considered.

Fused Filament Fabrication (FFF) has been the most widely used three-dimensional printing (3DP) technology due to its cost-effectiveness, easy application, and material readiness. FFF, to date, has been used to fabricate polymer components for rapid prototyping and increasingly for some end-user applications. Thus, there is a pressing need to optimize 3DP process parameters for FFF materials to achieve higher dimensional accuracy, especially in functional components for final use applications. Therefore, to ensure desired geometries with reasonable accuracy, precise measurements are required to validate the FFF process’s dimensional capability under different process conditions. This study presents the dimensional measurement and statistical analysis to evaluate the effect of printing materials, speed, and layer heights on dimensional accuracy and repeatability of the commercial FFF process. A benchmark part model was designed with different external and internal features commonly used in manufacturing processes. Taguchi’s design of experiments (DOE) was employed to obtain the experiments scheme, followed by the 3DP, dimensional measurement, and analysis of 3DP samples. Results revealed polylactic acid (PLA) material provided better dimensional control in most of the features. Higher printing speeds and layer heights were found optimum for external features/protrusions, whereas lower-to-medium speeds and layer heights were more appropriate for the fabrication of internal features.
