“…For instance, Lagalante et al designed cylindrical and conductive PLA sorbents using 3D printing (nozzle diameter: 0.4 mm and extrusion temperature: 215 °C) for removing VOCs, such as benzene, toluene, and ethylbenzene from wastewater (Figure c) . The authors anticipated that the infill density could be directly correlated with the removal performance, with the highest removal of VOCs (benzene: 50.6%, toluene: 81.3%, and ethylbenzene: 92%) obtained at 50% infill density after 5 h of treatment due to the increase in the effective surface area …”

“…Until now, 3D-printed membranes and their modules, adsorbents, and biocarriers have been widely explored for water treatment applications, including desalination, oil–water separation, water filtration, and heavy metal and organic contaminants removal as well as nuclear decontamination. Particularly for water desalination, 3D printing strategies offer advantages over conventional manufacturing techniques as they can be used to fabricate not only whole membrane systems and module components but also energy management components such as solar collectors and evaporators (Figure a) . Out of all 3D printing technologies, DLP is the most widely used approach for thermal and membrane desalination because of its excellent flexibility, high accuracy, and diverse material compatibility.…”

“…To print larger structures in order to meet industrial demands, printers with multiple nozzles are being employed to produce ceramic membranes for water treatment . In addition, researchers are also working toward developing user-friendly software that can be universally interfaced with all 3D printers for standardizing the production process. , Based on the aforementioned considerations, it can be anticipated that 3D printing technologies are getting ready for industrial applications but mostly for generating parts that are otherwise highly expensive to prepare using other manufacturing techniques. For complete adaptations, serial productions and 3D printing farms would be a stepping-stone in the manufacturing process; however, the process economics and complexities will play a major role in determining their success.…”

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.

“…[3,4] Currently, solar-to-vapor efficiency and operational stability are two of the most critical issues for solar interface evaporation systems. [5,6] Many strategies have been extensively investigated to enhance evaporation efficiency, such as constructing absorber materials with high photothermal conversion, [7,8] optimizing thermal management, [9,10] absorbing ambient heat, [11,12] enhancing air convection, [13] and reducing the latent heat of vapor. [14][15][16] However, the rapid evaporation of freshwater accelerates the enrichment of salt ions on the evaporation surface, and the operational stability of the device becomes a new problem.…”

Zero‐liquid‐discharge‐type solar interface evaporators have shown great potential for applications in areas such as desalination and salt production. Edge‐crystallization‐type evaporators using a single water supply column composition are widely investigated. However, the evaporator area is limited by the water supply capacity of a single water supply column, making it difficult to scale‐up. Herein, an evaporative area management (EAM) strategy is proposed to enable the evaporator to build a larger area by applying multiple water supply columns while avoiding crystallization on the evaporating surface. The salt‐tolerance performance and mechanism of the EAM strategy are investigated through experiments and simulations, and the optimal evaporation performance is achieved through parameter optimization. The seven‐stage multistage distillation device assembled with the optimized EAM strategy achieves a fourfold increase in evaporation area at 1 kW m−2 light intensity and 3.5 wt% NaCl solution with a stable evaporation rate of 1.8 kg m−2 h−1 and a salt yield of 66 × g m−2 h−1. In particular, the device maintains stable evaporation under 2 kW m−2 concentrated light conditions and 7 days of cyclic operation. Thus, this stable operation salt‐tolerance strategy provides a promising option for scale‐up desalination technology.
