3D printing device for flexible wires

Abstract

The invention provides a 3D printer for flexile wires, and relates to the technical field of 3D printing. The 3D printer for the flexible wires provided by the invention comprises a wire storage part,a wire supply part, a printing spray head, a wire limiting part and a printing platform, wherein the wire storage part is used for storing the flexible wires; the wire supply part is used for supplying the flexible wires to the printing spray head; the wire limiting part is positioned between a charge end of the printing spray head and a discharge end of the wire supply part for limiting deformation of the flexible wires; the printing spray head is used for printing the flexible wires onto a printing base material; and the printing platform is used for bearing the printing base material. According to the technical scheme adopted by the invention, the 3D printer can prevent the flexible wires from being deformed in a supply process.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a flexible wire 3D printer. Background technique [0002] 3D printing technology is also called additive manufacturing technology. The molding process is to use NX, Pro / E, SoliWorks, 3DMAX and other drawing software to carry out three-dimensional modeling on the products to be printed, and then export them into STL and other format files, and then use layering software Layering is performed to generate a GCODE file, and finally the GCODE file is imported into the 3D printer. The 3D printer reads the GCODE file, superimposes the printing material layer by layer on the printing substrate, and finally prints out the entire product. 3D printing technology can complete the manufacture of complex parts, shorten the research and development time, and produce products that are difficult to process by traditional processing methods. It has great development prospects in the fields of ...

Problems solved by technology

[0003] Fused deposition modeling (FDM) molding technology is often used in 3D printing technology. The inventors have found that when printing flexible wires using fused deposition modeling technology, such as figure 1 as shown, figure 1 Schematic diagram of the structure of the 3D printing device provided by the prior art. During the feeding process, the flexible wire 1' is easily distorted and deformed by the co-extrusion of the materials participating in the feed roller 2' and the printing nozzle 3'. Under the action, it is extruded from the gap between the print head 3' and the feed roller 2', causing the supply to be interrupted
