This review article discusses the fabrication strategies and environmental applications of 3D-printed metal-organic frameworks (MOFs) monoliths. It highlights the challenges and future directions for 3D-printed MOFs in environmental applications, such as water treatment and gas adsorption. The article summarizes various 3D printing techniques, including direct ink writing (DIW), seed-assisted in-situ growth, coordination replication from solid precursors, matrix incorporation, selective laser sintering (SLS), and digital light processing (DLP). Each technique is described with relevant examples, emphasizing their advantages and disadvantages. The review also explores the environmental remediation applications of 3D-printed MOF monoliths, particularly in gas separation and water purification. Finally, it presents future challenges and directions for the development of 3D-printed MOF monoliths, aiming to enhance their structural and functional properties for broader industrial applications.This review article discusses the fabrication strategies and environmental applications of 3D-printed metal-organic frameworks (MOFs) monoliths.
