Abstract

There has been a notable expansion of research addressing technological limitations and critical challenges of conventional membranes such as biofouling, energy consumption, and low flux. The inherent advantages of additive manufacturing (AM) or 3D printing (3DP) have led to significant breakthroughs in water filtration membranes in terms of material selection and prototype design to create innovative membranes, while the growing demand for efficient, sustainable, and multifunctional membranes has driven interest in advanced materials such as graphene oxide (GO). This review explores the potential of 3D-printed antibacterial membranes derived from waste-derived GO for liquid-phase separation processes. Graphene oxide (GO), renowned for its exceptional antibacterial properties, high surface area and hydrophilicity, has emerged as a promising material for membrane technology. This review highlights the integration of waste-derived GO into 3D-printed membranes, and the enhancement of their antibacterial activity for applications in water filtration. The paper also discusses the challenges faced in combining 3D printing with GO and provides an overview of recent advancements in the field, identifies existing gaps, and suggests future research directions for the development of sustainable, high-performance membranes. By combining the environmental benefits of waste-derived GO with the versatility of 3D printing, this technology presents a promising solution to address global water and sanitation challenges
