Abstract

The invention discloses a three-dimensional printer. The three-dimensional printer comprises an integrated framework, wherein a synchronous belt is arranged inside the integrated framework; a paralleldriving mechanism is arranged on the synchronous belt; the lower end of the parallel driving mechanism is provided with a double-spray constant-stroke closed wire feeding system; the lower end of thedouble-spray constant-stroke closed wire feeding system is provided with an effector; the lower end of the effector is connected with a printing sprayer; the bottom end of the interior of the integrated framework is provided with a hot bed which is located under the printing sprayer; consumables are arranged at the upper end of the integrated framework; and an integrated controller is arranged inside the integrated framework. The three-dimensional printer is high in rigidity, stable in structure, high in freedom degree, capable of eliminating the staircase effect of the traditional 3D printing, excellent in mechanical property of printed finished products, easy to maintain, capable of overcoming the defects of the 3D printing in the existing market and wide in the application range.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printers, in particular to a three-dimensional printer. Background technique [0002] 3D printer, a machine of rapid prototyping technology, is a technology based on a digital model file, using bondable materials such as special wax, powdered metal or plastic, to construct objects by layer-by-layer printing. It is often used in mold manufacturing, industrial design and other fields to make models or for direct manufacturing of some products, which means that this technology is becoming popular. The working principle of the so-called 3D printer is basically the same as that of ordinary printers, but the printing materials are somewhat different. The reason why it is popularly called "printer" is to refer to the technical principle of ordinary printers, because the process of layered processing is very similar to inkjet printing. This printing technology is called 3D printing technology. ...
