Abstract

The embodiment of the invention provides a 3D printing nozzle, a 3D printing nozzle assembly and a 3D printing method. The 3D printing nozzle comprises a nozzle body and material conveying channels arranged in the nozzle body, the first ends of the material conveying channels communicate with an external charging barrel, the second ends of the material conveying channels are used for outputting printing materials, and each material conveying channel is provided with an anti-backflow device in a series connection mode. Each anti-backflow device is configured to allow the printing material to flow from the first end of the corresponding material conveying channel to the second end in a one-way manner. The 3D printing nozzle assembly comprises a plurality of 3D printing nozzles which are arranged side by side. The 3D printing method is executed through the 3D printing nozzle or the 3D printing nozzle assembly. The 3D printing nozzle can output various printing materials, can effectively prevent the printing materials from flowing back, and meanwhile has the advantages of being simple in structure, low in cost, easy to use and control and the like.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing nozzle, a 3D printing nozzle assembly and a 3D printing method. Background technique [0002] 3D printing, as an emerging rapid prototyping manufacturing method, has become more and more familiar to people. It is a technology that constructs objects by layer-by-layer printing using special printing materials based on digital model files. It has the characteristics of rapid prototyping, no limitation of printing shape, high material utilization rate, distributed production and low assembly cost. This technology has a wide range of applications in aerospace, automotive and marine, biomedical, wearable devices, micro-nano sensing, flexible electronics and other fields. [0003] The traditional 3D printing nozzle has the phenomenon of backflow of the printing material, and the material conveying channel is easy to be blocked; at the same time, the general 3D print...
