Description

technical field [0001] The invention belongs to the technical field of preparation of materials for 3D printing, and in particular relates to a high-strength graphene 3D printing material. Background technique [0002] With the emergence of 3D printing products, 3D printing technology is gradually being understood by people. 3D printing technology is a kind of rapid prototyping technology. It is a technology based on vertical model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products. The raw materials that can be used for 3D printing include resins, metals, military, civil engineering, guns and other fields. [0003] Printing materials, which are the core components of 3D printing, have received extensive attention in recent years....
