Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that the electrospinning method used for 3D printing in the prior art mostly uses a single nozzle with a polymer material to achieve 3D printing, the printing quality and printing accuracy are low, and the manufacturing process is difficult. The material and color of the finished product are single, and the scope of application is small

Abstract

The invention discloses a 3D printing method based on electrostatic spinning. A three-dimensional model is drawn through a computer, and outline data and filling data of sections of all layers in the three-dimensional model are obtained; multiple high polymer materials are selected to manufacture multiple different 3D printing materials, and fiber wires of different materials are formed through different spinning spraying nozzles and a high-voltage electrostatic field of a working platform; and through laser irradiation, the fiber wires are deposited in the designated area of the working platform, manufacturing of a single-layer section structure is achieved, and manufacturing of the single-layer section structure is conducted repeatedly to complete 3D printing of the whole three-dimensional model. The multiple spinning spraying nozzles are arranged and matched with the multiple different printing materials to achieve 3D printing, the manufacturing requirement for the 3D printing materials is low, the printing quality is high, the printing precision is high, the printing materials are rich instead of simplex, the machining control is flexible, and the application range is wide. Color adding agents are added in the manufacturing process of the multiple 3D printing materials, so that the defect that the color of a finished 3D printing product is simplex is overcome.

Description

Technical field: [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing method based on electrospinning. Background technique: [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. Existing 3D printing technologies mainly include melt extrusion molding technology, selective laser sintering technology, and stereolithography molding technology. Among them, the melt extrusion molding technology needs to make the plastic material into a coiled filament before it can be use...
