Coaxial 3D printer nozzle and working method thereof

Abstract

The invention discloses a coaxial 3D printer nozzle and a working method thereof. The coaxial 3D printer nozzle comprises a support, an outer barrel, an inner barrel, a coaxial nozzle body, an extrusion piston and a linear driving device. The outer barrel is arranged at the bottom of the support; the inner barrel is arranged in the outer barrel and a cylinder cavity is formed; the coaxial nozzle body is arranged at the lower end of the outer barrel; the extrusion piston is movably arranged in the cylinder cavity; the linear driving device is arranged on the support and can drive the extrusion piston to reciprocate in the cylinder cavity. The coaxial 3D printer nozzle is reasonable in structural design, the outer barrel and the inner barrel are coaxially arranged ingeniously, different materials can be placed into the outer barrel and the inner barrel, then the two different materials are extruded at the same time through the coaxial nozzle body, printing time is saved to a large extent, printing quality is improved, 3D printer consumables do not need to be replaced when different colors or different material portions are printed, it is only needed that the linear driving device and a compressor are correspondingly controlled to be in a work state or in a stop state, and the coaxial 3D printer nozzle is easy and convenient to use and favorable for wide application and popularization.

Description

technical field [0001] The invention relates to the technical field of 3D printer nozzles, in particular to a coaxial 3D printer nozzle and a working method thereof. Background technique [0002] Now, with the maturity of 3D printing technology, 3D printing is also used in various fields such as: aerospace industry, cultural relics industry, automobile industry, medical industry, music industry, etc. Now 3D printers have become more and more desktop-oriented. There are also many printing materials such as plastic, metal, plaster, etc., but the nozzles of these printers can only print one material at a time. Since many products have two or more different colors or are composed of two or more materials of different materials, the existing 3D printers need to be frequently replaced when printing three-dimensional products composed of multiple colors or multiple materials. Raw materials are not only troublesome to operate, but also the printing quality of the product will be af...

[0002] Now, with the maturity of 3D printing technology, 3D printing is also used in various fields such as: aerospace industry, cultural relics industry, automobile industry, medical industry, music industry, etc. Now 3D printers have become more and more desktop-oriented. There are also many materials to print, such as plastic, metal, plaster, etc., but the nozzles of these printers can only print one material at a time

Since many products have more than two different colors or are composed of two or more materials of different materials, the existing 3D printers need to be frequently replaced when printing three-dimensional products composed of multiple colors or materials. Raw materials, not only the operation is troublesome, but also the printing quality of the product will be affected due to the existence of residual material in the nozzle
