Abstract

The invention discloses a 3D printing material and a 3D printing product based on oxidized graphene and preparation methods of the 3D printing material and the 3D printing product. Main ingredients of the 3D printing material based on the oxidized graphene are the oxidized graphene, aniline and water. By the characteristic that electrostatic attraction, hydrogen bonds and Pi-Pi interact between the oxidized graphene and the aniline, the oxidized graphene and the aniline are combined with each other together to prepare the 3D printing material, the range of raw materials of the 3D printing material is expanded, moreover, the prepared 3D printing material is suitable in viscosity and can be formed at normal temperature without being heated, therefore, the 3D printing material can meet requirements of 3D printing, a corresponding 3D printing process and structures of devices can be simplified to reduce costs for 3D printing, and then the 3D printing material is suitable for large-scale production of 3D printing products.

Description

technical field [0001] The present invention relates to the field of 3D printing, in particular to a graphene oxide-based 3D printing material, 3D printing product and their preparation method. Background technique [0002] 3D printing is known as another industrial revolution subverting the traditional manufacturing industry. It is mainly a processing technology that uses the characteristics of extruded and rapid prototyping of printing materials and uses computers as numerical control. 3D printing technology has a very broad application prospect. [0003] Existing 3D printing materials are usually thermoplastic materials or alloy materials, which have very low viscosity and poor formability at room temperature. Therefore, in the printing process of current 3D printing materials, it is usually necessary to melt the materials at high temperature and then press them according to the preset Programs are extruded or tiled and finally solidified into shape. In view of the curre...
