The Design of Automatic Silk Material Replacement Device on 3D Printers Based on FDM Technology

The overall design of the mechanical structure of the color 3D printer is put forward, and a new spliced print head structure is proposed. The utility model relates to a splicing type print head, which is composed of a print head which is loaded with different colors of silk material and a movable fixing device of a spray head. The print head spliced through a nozzle fixing device of an elastic spring mechanism locking positioning clamping space forming and the print head, the splicing type print head in the two part of the implementation of the print head movement path splicing preset, and then through the automatic replacement process of printing head fixing device and mobile splicing nozzle with different colors from to achieve different color silk. An automatic replacement device of the wire material is designed. By testing the automatic replacement device of the wire material, it is proved that the automatic replacement of silk material in line with color 3D printing in the automatic replacement of silk material requirements.
