3D printer capable of circularly supplying materials

Abstract

The invention relates to the field of 3D printers, in particular to a circular feeding 3D printer which comprises a machine body and a feeding box arranged at the top of the machine body, a feeding opening is formed in the upper side wall of the feeding box, a feeding pipe is fixedly connected to the lower side wall of the feeding opening, a plurality of wire coils wound with wires are arranged in the feeding pipe, and the wire coils are fixedly connected with the feeding box. The wire rods comprise the head end wire rod and the tail end wire rod, a wire inlet is formed in the bottom of the feeding box, the wire rods penetrate through the wire inlet to supply materials to the machine body, a supporting plate is fixedly connected to the lower side wall of the feeding box, a fixing shaft is inserted into the side wall of the wire coil, and the lower end of the fixing shaft is fixed to the upper side wall of the supporting plate. The side wall of the wire coil is sleeved with a rotating ring set, and the rotating ring set is rotationally connected with the side wall of the wire coil. According to the 3D printer capable of achieving circulating feeding, automatic circulating feeding of wires of the 3D printer is achieved, the connecting strength of the wires is guaranteed, using is more convenient, the production efficiency is improved, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a 3D printer with recyclable material supply. 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. The working principle of 3D printers is basically the same as that of ordinary printers, except that the printing materials are somewhat different. The printing materials of ordinary printers are ink and paper, while 3D printers are equipped with different "printing materials" such as metal, ceramics, plastics, sand, etc., which can be "printed" A device that produces real 3D objects. [0003] At present, the raw materials for 3D printing on the market are usually supplied by fuse wire reels. However, at present, 3D printers take a very long time to print. Large and complex prints may take three to...

AI Technical Summary

Problems solved by technology

However, at present, 3D printers take a very long time to print. Large and complex prints may take three to four days, and small handicrafts may take up to three hours. Consumption and printer working conditions increase labor intensity and affect production efficiency

And often there will still be a series of problems such as insufficient materials in the printing process of the 3D printer, which will cause the printer to run empty, resulting in product scrapping, etc.
