Abstract

The invention provides a composite 3D printing material and a preparation method thereof. The composite 3D printing material is characterized by being prepared from, by weight, 40-100 parts of polyetherimide, 40-100 parts of epoxy resin, 5-10 parts of inorganic fillers, 5-20 parts of coupling agents, 0.1-0.5 part of light stabilizers, 0.1-2 parts of flatting agents, 0.1-2 parts of antioxidants, 0.1-2 parts of degassing agents and 1-6 parts of dispersed lubricants. Compared with a traditional polyetherimide material, the polyetherimide composite 3D printing material has higher strength and hardness and can be used at high temperature.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a preparation method of a composite 3D printing material. Background technique [0002] 3D printing is a rapid prototyping technology based on digital model files and using bondable materials such as powdered metal or plastic. It is known as another industrial revolution that subverts traditional manufacturing. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), dental and medical industries, education, geographic information systems, civil engineering, automotive, aerospace, firearms, and others. Since the birth of 3D printing, it has transformed from industrial and architectural model printing to functional and service products. In the context of future intelligent manufacturing, 3D printing technology will integrate with other advanced technologies such as the Internet, cloud computing, Inter...
