Multi-nozzle 3D printer

Abstract

The invention relates to a multi-nozzle 3D printer which comprises a rack, a portal frame, a printing platform, a nozzle fixing frame and a nozzle disc frame. The printing platform is arranged on the rack, a feeding mechanism for a printing material is fixed on a portal frame horizontal plate on the upper portion of the portal frame, the nozzle fixing frame is arranged below the portal frame horizontal plate, a first clamping jaw cylinder is fixed on the nozzle fixing frame, the nozzle disc frame is arranged on the right of the portal frame and arranged on the rack, multiple second clamping jaw cylinders are fixed on a nozzle disc, and each second clamping jaw cylinder is provided with a second clamping jaw cylinder clamping jaw. In a printing state, non-working nozzles are fixed on the nozzle disc, the second clamping jaw cylinder clamping jaws firmly grasp third steps of the nozzles, and each second clamping jaw cylinder is provided with a magnetic switch; working nozzles go onto the nozzle fixing frame through a rotating mechanism and a propelling mechanism, a first clamping jaw cylinder clamping jaw firmly grasps fifth steps on the nozzles, and the first clamping jaw cylinder is provided with a magnetic switch.

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 ...

Problems solved by technology

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 the workpiece. In order to avoid this problem, the printing size of the workpiece has to be reduced. Moreover, the dual / multi-nozzle 3D printers on the market generally only print support materials and finished materials, which are difficult to meet the assembly requirements. product design requirements
