Description

Technical field [0001] The invention relates to the technical field of 3D printing materials, in particular to a super-high conductivity carbon fiber composite wire used for 3D printing. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology that builds objects based on digital model files and uses bondable materials such as powdered metal or plastic wires to print layer by layer. [0003] 3D printing is usually achieved using digital technology material printers. It is often used to make models in mold manufacturing, industrial design and other fields, and then gradually used in the direct manufacturing of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, guns, and other ...
