Abstract

The invention relates to the technical field of 3D printers, and discloses a 3D printing extrusion device and a 3D printer. The 3D printing extrusion device comprises a feeding part, a driving gear, afirst driven gear and a second driven gear, wherein a discharging channel is formed in one end of the feeding part, and a first feeding channel and a second feeding channel which are connected with the discharging channel are formed in the other end of the feeding part; the driving gear is arranged at the ends, away from the discharging channel, of the first feeding channel and the second feedingchannel; the first driven gear can be selectively meshed with the driving gear so as to supply materials to the first feeding channel; and the second driven gear can be selectively meshed with the driving gear so as to supply the materials to the second feeding channel. The first feeding channel and the second feeding channel are arranged on the feeding part, the two feeding channels are used forsupplying the materials to the discharging channel in sequence, the first driven gear and the second driven gear are selectively meshed with the driving gear to achieve automatic material changing, and the printing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printing extrusion device and a 3D printer. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology, also known as additive manufacturing. It is based on digital model files, using powdered metal or plastic and other bondable materials to construct by layer-by-layer printing. object technology. [0003] At present, for 3D printers using rod-shaped materials, when a rod-shaped material is used, it is usually necessary to stop printing and replace the material, which greatly reduces the printing efficiency. [0004] Therefore, there is an urgent need for a 3D printing extrusion device to solve the above problems. Contents of the invention [0005] Based on the above, the object of the present invention is to provide a 3D printing extrusion device and a 3D printer, which can automatically change materials and have high printing efficien...
