3D (Three-Dimensional) printing machine

Abstract

The invention discloses a 3D (Three-Dimensional) printing machine. The problem of the low efficiency existing in a conventional printing machine is solved. The 3D printing machine is characterized bycomprising a frame, a movement module, a printing device and a load bearing device, wherein the printing device is connected with the frame through the movement module, and is provided with two groupsor more of material boxes; the material boxes are connected with the printing device through material conveying pipelines; the printing device is provided with a spray head placer; the spray head placer is provided with four groups or more of different specifications of printing spray heads; the printing spray heads comprise at least two groups of spray heads with different material output apertures and at least two groups of spray heads with different plastic output apertures; the spray head placer is connected with the printing device through a rotating shaft; the printing device is also provided with a cooling liquid pipeline and an air jetting pipeline; the cooling liquid pipeline is connected with a cooling liquid storage box; the air jetting pipeline is connected with an air compressor; two groups of the load bearing devices are arranged and are arranged on a conveying track; two ends of the conveying track are guided to the outer edges of the frame respectively. The 3D printingmachine can be used for effectively shortening a time needed for producing a work piece, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to a 3D printer. Background technique [0002] A 3D printer is a rapid prototyping device that uses digital simulation files to build objects in a layer-by-layer manner using sticky materials such as metal or plastic. The workpiece constructed by the 3D printer does not need to be realized by traditional cutting machine tools and molds. Under the control of the computer, the three-dimensional entity can be directly formed according to the three-dimensional model data of the workpiece. [0003] The print head is a part used to output consumables in the 3D printer. In the prior art, the print head is often only equipped with a set of nozzles, and a specific nozzle can only output specific consumables. When it needs to be applied to multiple materials to produce workpieces During the event, it is difficult for this kind of 3D printer to work efficiently, and it is necessary to man...

AI Technical Summary

Problems solved by technology

[0005] To sum up, traditional 3D printers produce workpieces that need to be composed of different consumables, produce workpieces with large changes in size or precision, alternately produce workpieces with large sizes and low precision, and small precision workpieces. When the workpiece is high, and when the finished workpiece needs to be frequently transferred to the working state outside the machine, it cannot face the changing production conditions, and the production efficiency will be significantly reduced.
