Abstract

Additive manufacturing (AM) is considered as an innovative technology for the production of complex structures for a wide range of applications. Herein we explain the main three-dimensional (3D) printing systems including fused deposition modeling (FDM), direct ink writing (DIW), stereolithography (SLA), and selective laser sintering (SLS). The primary demands for the selection of successful inks based on polymers, graphene or its derivatives, and their composites, as well as the multifunctional applications of the 3D printed graphene composite structures, are discussed. Despite the great advancement in investigating the mechanical, electrical, and thermal characteristics of these materials, more research and development are required for their inherent potential. This chapter overviews the latest research studies on 3D printed graphene-based nanocomposites for different applications such as biomedical, sensor, and energy storage applications. Finally, the challenges in 3D printing and future prospects are identified.
