Non-supporting magnetic suspension type omnidirectional 3D printing system and method

Abstract

The invention discloses a non-supporting magnetic suspension type omnidirectional 3D printing system and method. The 3D printing system comprises a printing managing control system, a control computer, a printing head adjusting device, a printing head flow speed control device, a printing part cooling device, a printing part suspension device, a printing head assembly and a printing material. Theprinting part suspension device comprises at least one or a plurality of electromagnets, a magnetic suspension principle is used, the magnetism is used for overcoming the gravity, and suspension of aprinting part in a printing space is realized. The printing part suspension device further comprises a printing part position sensor, a weight sensor, a self-stabilizing system, an electromagnet arraycontrol module and an electromagnet array formed by arrangement of the multiple electromagnets; and the printing part suspension device can perform precise control and adjustment on the suspension position and direction of the printing part. The printing head assembly comprises one or a plurality of printing heads, the printing head assembly can spray or deposit the printing material from a plurality of directions towards a printing base piece, and printing of the printing part can be finished at a time.

Description

technical field [0001] The invention relates to a 3D printing device, in particular to an unsupported magnetic levitation omnidirectional 3D printing system applied to 3D intelligent manufacturing. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files, using bondable materials such as powdered metal or plastic, and constructing objects by layer-by-layer printing. 3D printing usually uses Digital technology material printer to achieve. It is often used to manufacture models in mold manufacturing, industrial design and other fields, and is gradually used in the direct manufacture of some products. [0003] There are already parts printed using this technology. This technology has a wide range of applications in industrial design, architectural engineering construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and weapon manu...

AI Technical Summary

Problems solved by technology

[0005] 1) When printing an object, traditional printers can only print the part above the plane, while the printing below the plane needs to be printed separately, or through other supporting processes, the upper and lower parts are combined and fixed, and the printing is finally completed; this printing method forms The integrity and structural strength of the object will be affected to varying degrees

[0006] 2) Existing 3D printing systems generally only have one print head, even if multiple print heads are used, they can only print layer by layer, and the printing efficiency is low

[0007] 3) The printed parts of the existing 3D printing system often need to be fixed by external equipment before they can be sprayed or deposited on the outside. After the printing is completed, the supporting and fixing device needs to be removed, which cannot be completely printed at one time

[0008] 4) During the printing process of the existing 3D printing system, due to the support and fixing device connected to the printing part, the printing position and angle are limited, and multi-directional simultaneous printing cannot be realized

[0009] 5) Existing suspension 3D printing systems, such as CN105965899A and CN 106217873 A, have an imperfect structure of the suspension device, especially the control accuracy of the suspension device is not high, and the magnetic force and direction control are not accurate enough, so that the 3D printing accuracy is not high
