Electron beam thermosetting resin 3D printing and application thereof

Abstract

The invention discloses a method for realizing 3D printing by using an electron beam thermosetting resin material. Resin is conventional thermosetting resin, a heat source is a fine micro-nano array electron beam source specially applied to rapid curing of the thermosetting resin; as for the resin fully paved with substrates, an electron beam heating source is controlled by adopting single fine electron beam quick scanning or large-area electron beam sources, switches or other mechanical means, thermal curing of the resin is achieved, and next-layer resin coating, full tiling and selective thermal curing are carried out, and a 3D printing process is achieved. A current thermosetting 3D printing technology cannot meet the high-precision 3D printing requirement; a high-precision 3D printinglight-curing 3D printing technology is achieved, photocurable resin or an optical system are expensive, and widespread application and popularization are difficult to achieve. The method achieves fine3D printing of the thermosetting resin, and the electron beam technology is applied to a 3D printing process of the resin material.

Description

technical field

[0001] The invention belongs to the field of true 3D printing additive manufacturing, and specifically relates to the design, manufacture, process, and product development and application of a 3D printing device that uses electron beam heating and curing resin to realize 3D printing of fine micro-nano structure products. Background technique

[0002] 3D printing technology has received more and more attention and has been initially applied in many fields. The reason is that, first, 3D printing technology is the fusion of computer image processing, stereoscopic imaging and decomposition, advanced materials, precision machinery and other new technologies. It has a strong technical allure; second, 3D printing belongs to additive manufacturing. In the process of product manufacturing, there is no discarding or useless consumption of materials, which meets the current trend needs of energy saving, environmental protection and efficient development; third, it is esp...
