Access to clean and affordable drinking water remains a critical global challenge, particularly in developing regions. Traditional water filtration methods, while effective, often suffer from high costs, limited accessibility, and environmental concerns. This research explores the potential of 3D-printed water filters as a customizable, cost-effective, and sustainable solution for water purification. By leveraging additive manufacturing technologies, 3D printing allows for the design and production of filtration systems tailored to specific water quality challenges. This paper examines the materials used in 3D-printed filtration systems, including biopolymers, graphene-infused composites, and activated carbon structures, assessing their efficiency in removing contaminants such as heavy metals, bacteria, and microplastics. Additionally, the study evaluates the economic feasibility and environmental impact of 3D-printed filters compared to conventional filtration technologies. Through a combination of literature review, experimental analysis, and case studies, this research highlights the advantages of 3D-printed filters in terms of affordability, scalability, and sustainability. The findings suggest that 3D printing has the potential to revolutionize water purification, particularly in low-resource settings, disaster-stricken areas, and off-grid communities. However, challenges such as durability, regulatory approval, and mass production scalability must be addressed to enable widespread adoption. This study contributes to the growing field of sustainable water technologies, paving the way for further advancements in decentralized and cost-efficient filtration solutions.
