ABSTRACT

Additive manufacturing, which is also known as three-dimensional (3D) printing, is a new, layer-by-layer prototyping technique for fabricating unlimited, creative, and complex geometries. A wide range of materials, including polymers and inorganic ingredients, can be utilized in this technology. Owing to its numerous advantages, it has been found as a panacea for different purposes, such as engineering and medical applications. Recently, researchers have started searching for 3D printing usage for fabricating and engineering membrane-based separation systems. In this chapter, the key information has been provided on the 3D printing technique for fabricating the next generation of greener membrane engineering for sustainable water treatment, mostly in the three main categories including membrane fabrication, channel spacer, and module design. Moreover, the promising potential and limitations of the 3D printing technique for membrane engineering, as well as future prospects of this technology, have been all discussed, comprehensively. Significant growth in membrane engineering is expected in the near future owing to the environmentally friendly potential benefits in using 3D printing in this field.
