The application of MXenes in additive manufacturing is a groundbreaking strategy for green fabrication, thereby paving the way for innovative applications for enhanced energy storage, flexible electronics, and biomedical devices. MXenes are a group of two-dimensional transition metal carbides and nitrides that possess superior electrical conductivity, mechanical strength, and surface chemistry tunability, which make them competent candidates for high-performance functional materials. Additive manufacturing, due to its stepwise building process, maximizes the use of resources by minimizing material waste, energy, and environmental footprint. Environmentally friendly synthesis methods of MXenes in different additive manufacturing methods, including fused deposition modeling (FDM), digital light processing (DLP), direct ink writing (DIW), and inkjet printing, are covered in this chapter. Every method gives unique benefits regarding structural integrity, electrical characteristics, and sustainability, enabling customized, high-precision, and green components to be created. The combination of MXenes and additive manufacturing is not only speeding up advancements in advanced materials but also supporting global sustainability objectives by driving greener production processes. Future studies should be directed towards optimizing MXene formulations, advancing processing techniques, and exploring scalable fabrication methods to optimize their prospects for industrial and commercial applications.
