Annular 3D (three-dimensional) printing device

Abstract

The invention relates to the material processing technology field, in particular to an annular 3D (three-dimensional) printing device. The annular 3D printing device comprises a workbench and a printing mechanism, wherein the printing mechanism comprises a support assembly, six groups of spray heads, six groups of displacement assemblies, six groups of conveying assemblies and six groups of heating assemblies, and further comprises a controller and a rotation mechanism, the rotation mechanism comprises a drive assembly and a driven assembly, the drive assembly is arranged at one end, far awayfrom the top of the controller, of the workbench, the driven assembly is arranged between the controller and the drive assembly, and the conveying assemblies, the heating assemblies and the six groupsof the spray heads are all electrically connected with the controller. The annular 3D printing device further improves use rate of a 3D printer for a printing space, and satisfies printing for certain cambered articles, thereby guaranteeing that the articles printed out are excellent in quality and exquisite in appearance, and meanwhile accurately controls a proportion of printing materials, improves use rate of the printing materials, avoids waste of the materials, and then saves resources, and reduces printing cost.

Description

technical field [0001] The invention relates to the technical field of material processing, in particular to an annular 3D printing device. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. [0003] 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others. [0004] The current 3D printing equip...

AI Technical Summary

Problems solved by technology

[0004] The current 3D printing equipment is mostly linear 3D printers, and the printing method is straight and straight. This printing method is not suitable for printing some curved surface objects. At the same time, the utilization rate of the printing space is low, which will cause the printed objects to be less exquisite. , the texture is poor, and usually the feeding method of printing materials is mostly manual feeding. This feeding method cannot accurately control the proportion of printing materials, so it is easy to cause waste of printing materials, not only easy to cause pollution to equipment, At the same time, resources are wasted, printing costs are increased, and revenue is reduced
