Abstract:: The excellent mechanical, electrical and thermal properties of graphene enable its promising applications in the field of new functional materials. How to realize the largescale controllable construction of graphene micronanoscale units and promote the application of its excellent performance at the macro level has become one of the most essential challenges at present. Among the many controllable preparation methods of 3D graphene monoliths, 3D printing can realize multiscale controllable construction of graphene and other functional component materials via precise cutting, structural complexity, controllable design of geometric dimensions and component distribution optimization. The 3D printed graphene monoliths exhibit better mechanical, electrical and thermal properties than those of other conventional carbon nanomaterials. It is one of the most important frontier areas for graphene functional materials research. This article reviews several 3D printing methods that are currently applied to the preparation of macroscopic monoliths of graphene, as well as applications in various functional materials and devices. Based on these new techniques of 3D printing, it is expected to realize rapid and largescale production of graphenebased functional composites, biomedical materials, highperformance electronic components, flexible energy storage devices, smart sensor devices, to name a few.
