Embodiment 1

[0040] This embodiment provides a three-dimensional printing device, such as figure 2 As shown, it includes a printing table 1 and a printing tank 2. The printing tank 2 is used to accommodate materials for forming three-dimensional products. The printing table 1 is placed in the printing tank 2 to carry the three-dimensional products formed after exposure. It also includes a switch layer 3, The exposure light source 4 and the control unit 5, the switch layer 3 are set corresponding to the groove bottom of the printing tank 2; The exposure light passes or does not pass, so that the material in the printing tank 2 is exposed to form an exposure pattern.

[0041]By setting the switch layer 3, the exposure light source 4 and the control unit 5, the three-dimensional printing device can realize the exposure of the material in the printing tank 2 through a simpler structure and principle, so that the three-dimensional printing of the three-dimensional printing device is simpler an...

Embodiment 2

[0060] This embodiment provides a three-dimensional printing device. The difference from Embodiment 1 is that the control unit is used to control the switch element to be turned on or off frame by frame, so that the material is exposed layer by layer to form an exposure pattern. That is, the switching elements are controlled by frame-by-frame scanning to form the exposure pattern of each layer of material.

[0061] In this embodiment, the control unit is used to control the exposure light source to be turned off after the exposure of the previous layer of material is completed; and to control the exposure light source to be turned on after the printing platform moves the thickness of one layer of material to expose the next layer of material . Such setting can not only shorten the exposure time of each layer of material relatively, and prevent false exposure during the time period from the end of the exposure of the previous layer of material to the start of the exposure of th...

Abstract

The invention provides a three-dimensional printing device and a three-dimensional printing method. The three-dimensional printing device comprises a printing platform and a printing trough, the printing trough is used for containing material for forming a three-dimensional product, the printing platform is arranged in the printing trough, and is used for bearing the three-dimensional product which is formed after exposure, the three-dimensional printing device also comprises an opening and closing layer, an exposure light source and a control unit, and the opening and closing layer is arranged corresponding to the bottom of the printing trough; the exposure light source is arranged corresponding to the opening and closing layer; the control unit can control the on-off of the exposure light source and the opening and closing of the opening and closing layer, so that the exposure light emitted by the exposure light source can pass or cannot pass, and thereby the material in the printing trough is exposed to form an exposure pattern. By arranging the opening and closing layer, the exposure light source and the control unit, the three-dimensional printing device can expose the material in the printing trough by means of the simpler structure and principle, consequently, the three-dimensional printing of the three-dimensional printing device is simpler, the structure is also simplified greatly, and moreover, the cost of the equipment is reduced as well.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional printing, in particular, to a three-dimensional printing device and a three-dimensional printing method. Background technique [0002] Three-dimensional (3D) printing technology is based on the computer three-dimensional design model, through the software layered discrete and numerical control molding system, using laser beams, hot-melt nozzles, etc. to process special materials such as metal powder, ceramic powder, plastic, cell tissue, etc. Stacking and bonding layer by layer, and finally stacking and forming, a physical product is manufactured. Unlike the traditional manufacturing industry, which shapes and cuts raw materials through mechanical processing methods such as moulds, turning and milling to finally produce finished products, 3D printing transforms a three-dimensional entity into several two-dimensional planes. The manufacturing complexity is reduced. This digital ...
