Feeding device of 3D printer

Abstract

The invention discloses a feeding device of a 3D printer, and relates to the technical field of 3D printers. The feeding device of the 3D printer comprises a short-range wire feeding structure, and the short-range wire feeding structure is installed at the upper part of a short-range material extrusion nozzle; the feeding device of the 3D printer further comprises a long-range wire feeding structure; and the long-range wire feeding structure comprises a driving part and an execution part, wherein the driving part is arranged on the outside surface of a rack of the 3D printer, the execution part is in power connection with the driving part, the driving part provides power for driving the execution part to work, the execution part is used for dragging a wire rod, and the execution part can move up and down on the outer surface of the rack so that the position of the execution part on the rack can be adjusted. According to the device, the short-range wire feeding structure and the long-range wire feeding structure are designed, printing of different characteristic materials can be realized at the same time, meanwhile, the design that the execution part is adjustable enables the long-range wire feeding structure to be suitable for a plurality of wire rods with different flexibility, the application range of the device is expanded, and practicability of the device is further improved.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printer feeding device. Background technique [0002] The dual-nozzle 3D printer feeding system is a new technology that can be used in additive manufacturing. This system can use two nozzles to print materials with different characteristics at the same time, especially for printing complex models. At present, the dual nozzles of 3D printers all have a two-way short-distance wire feeding structure, and they can only print wires with similar material characteristics at the same time. The printing effect of wires with greatly different material characteristics is not good, or it cannot be printed. Contents of the invention [0003] In view of this, the purpose of the present invention is to propose a 3D printer feeding device, which improves the printing effect of the 3D printer for the problem of poor printing effect of wire rods with large differences in material chara...
