Description

technical field

[0001] The invention relates to the field of 3D printing, in particular to a multi-nozzle 3D printer. Background technique

[0002] 3D printing technology is a rapid prototyping technology based on digital model files, moving powdery metal or plastic and other bondable materials, and constructing objects by layer-by-layer printing. Among them, due to the expiration of the 3D printing patent technology of Fused Deposition Modeling (FDM), a large number of open source 3D printers have emerged, and FDM desktop 3D printers have gradually entered the field of vision of ordinary people. However, 3D printers with single nozzles are commonly used in the market at present. During the printing process, the nozzles need to be replaced manually. The operation is complicated and the efficiency is low. At the same time, problems such as height adjustment errors may occur after replacement. The rubbing problem is easy to occur during printing, which affects the quality of ...
