A Review of the Application of 3D Printing Technology in Textile Wastewater Treatment

Dyes, heavy metals, and other pollutants in the wastewater of various industries have caused concern among researchers and environmentalists. Researchers have proposed multiple materials in recent years as high-performance, biocompatible adsorbents. Today, 3D printing technology has attracted the attention of many researchers in various fields due to its significant potential for the rapid production of structures with complex and porous geometry compared to conventional processes. In recent years, 3D printing of polymer-based materials has been used in wastewater treatment and dye removal processes due to its high flexibility in the design of complex structures. Therefore, while introducing different types of 3D printers in this review, we have tried to express the manufacturing processes' challenges and characteristics. In addition, recent advances in the development of 3D printing structures and their application in removing pollutants such as dyes and heavy metals from wastewater have been studied.
