“…Remarkably, these microparticles can be easily eliminated using a hydrophilic volatile acid (such as HCl), ensuring the absence of toxic residues post-fabrication, which is preferred over conventional particulate leaching using organic solvents, such as dimethylformamide [24]. The acid treatment does not affect the morphology and surface of 3D printed Alg scaffolds because the Alg structure is chemically inert to HCl [25].…”

The integration of scaffolds, signalling cues, and cellular components is essential in tissue engineering to create an in vivo equivalent environment that supports physiological function. Scaffolds provide mechanical reinforcement for cellular proliferation and differentiation while providing cues that instruct the development of cells during culture. Alginate (Alg) is a versatile biopolymer for scaffold engineering. However, due to a lack of intrinsic cell-binding sites, thus far, Alg must be functionalized for cellular adhesion. Here, we demonstrate proof-of-concept, bioactive additive-free, microstructured Alg (M-Alg) scaffolds for neuron culture. The M-Alg scaffold was formed by introducing tetrapod-shaped ZnO (t-ZnO) microparticles as structural templates in the Alg that were subsequently removed. These transparent, porous, additive-free Alg-based scaffolds with neuron affinity are promising for neuroregenerative and organoid-related research.

The ability of alginates to form hydrogel solutions makes them a promising biomaterial for three-dimensional (3D) printing. Researchers are investigating several techniques to improve the alginate hydrogels’ quality, such as using alginate-based nanocomposites as materials for 3D printing. This review examines the material of alginate-based composites, the printing technique, and the applications of 3D printing alginate-based composites. Material composites for 3D printing include alginate with clay, a combination of alginate with polymers or biopolymers, and a mixture of alginate with metal oxide and carbon. The 3D printing material from alginate combined with polymers is usually used in the medical and green packaging industries, whereas a mixture of alginate with clay, metal oxide, and carbon 3D printing material is utilized in the environmental field. When considering printing procedures, extrusion techniques are the most affordable. Furthermore, the purpose of alginate composite characterization is to determine the impact generated by the material combinations. This characterization is carried out based on the intended application. However, it is common to employ mechanical, thermal, rheological, scanning electron, XRD, and FTIR analysis to identify the fundamental characteristics of the alginate composite according to research.

“…Typically, photoreactors have been 3D printed and functionalized photocatalysts such as graphitic carbon nitride (GCN) and ZnO for the degradation of dye molecules, which displayed high degradation efficiency and recyclability. The remarkable ability of 3D printing in designing complex geometrical structures has also paved the way for treating highly dangerous radioactive or nuclear waste, such as cesium-137, strontium-90, and tritium, in wastewater (Figure e) . 3D-printed materials were used as active supports and were coated with functional materials such as MOFs and zeolites for removing nuclear waste in the long run with high efficiency …”

The increasing levels of water pollution pose an imminent threat to human health and the environment. Current modalities of wastewater treatment necessitate expensive instrumentation and generate large amounts of waste, thus failing to provide ecofriendly and sustainable solutions for water purification. Over the years, novel additive manufacturing technology, also known as three-dimensional (3D) printing, has propelled remarkable innovation in different disciplines owing to its capability to fabricate customized geometric objects rapidly and cost-effectively with minimal byproducts and hence undoubtedly emerged as a promising alternative for wastewater treatment. Especially in membrane technology, 3D printing enables the designing of ultrathin membranes and membrane modules layer-by-layer with different morphologies, complex hierarchical structures, and a wide variety of materials otherwise unmet using conventional fabrication strategies. Extensive research has been dedicated to preparing membrane spacers with excellent surface properties, potentially improving the membrane filtration performance for water remediation. The revolutionary developments in membrane module fabrication have driven the utilization of 3D printing approaches toward manufacturing advanced membrane components, including biocarriers, sorbents, catalysts, and even whole membranes. This perspective highlights recent advances and essential outcomes in 3D printing technologies for wastewater treatment. First, different 3D printing techniques, such as material extrusion, selective laser sintering (SLS), and vat photopolymerization, emphasizing membrane fabrication, are briefly discussed. Importantly, in this Perspective, we focus on the unique 3D-printed membrane modules, namely, feed spacers, biocarriers, sorbents, and so on. The unparalleled advantages of 3D printed membrane components in surface area, geometry, and thickness and their influence on antifouling, removal efficiency, and overall membrane performance are underlined. Moreover, the salient applications of 3D printing technologies for water desalination, oil–water separation, heavy metal and organic pollutant removal, and nuclear decontamination are also outlined. This Perspective summarizes the recent works, current limitations, and future outlook of 3D-printed membrane technologies for wastewater treatment.
