Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a graphene-based 3D printing non-light-curable model wax. Background technique [0002] Rapid prototyping technology is one of the rapidly developing manufacturing technologies in the world today. It is a new type of manufacturing technology that emerged and developed in the late 1980s. It is an integration of CAD, numerical control technology, precision machinery, and material science and engineering technology. It can Quickly turn design ideas into structural and functional prototypes or direct-to-manufacture parts. This method can simply and fully automatically produce complex three-dimensional shapes that have been difficult to produce by various processing methods in the past, and has an epoch-making role in the field of processing technology. [0003] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondab...
