Embodiment 1

[0029] Example 1 - Ascending UV Micro LED Flat Panel Display Photocuring 3D Printing Device

[0030] refer to figure 1 The three-dimensional printing device based on the ultraviolet LED micro-display technology provided in this embodiment includes: a computer system 1, a controller 2, an ultraviolet LED micro-display device, a material tank 6, a forming table 8 and a lifting device 9;

[0031] Wherein, the computer system 1 performs image processing on the three-dimensional model, and divides the three-dimensional model into a series of cross-sectional graphics with thickness. Then, the processed data is sequentially transmitted to the controller 2, the display driving circuit 3, and the miniature ultraviolet LED chip array 4 through the data line.

[0032] In the embodiment, the display driving circuit 3, the micro-ultraviolet LED chip array 4, and the cover plate 5 are mainly used as an ultraviolet Micro LED flat-panel display device to realize the display of ultraviolet pa...

Embodiment 2

[0038] Example 2—Sunken UV Micro LED Flat Panel Display Photocuring 3D Printing Device

[0039] refer to figure 2 , different from Embodiment 1, in this embodiment, the ultraviolet Micro LED display assembly is located above the entire device, and the trough 6 and molding table 8 are located below the entire device. Forming table 8 utilizes lifting device 9 to be able to do vertical movement in the trough. Between the bottom surface of the cover plate 5 and the forming table 8 is the forming working area of ​​the three-dimensional printer.

[0040] Before printing starts, the photocurable resin 7 is filled in the material tank 6 . Forming platform 8 descends to the position apart from cover plate 5 bottom surface unit height.

[0041] When printing starts, the controller 2 controls the display drive circuit 3 to selectively drive and light up the ultraviolet LED chip array 4, and the emitted ultraviolet light image passes through the cover plate 5 and reaches the space abo...

Embodiment 3

[0043] Example 3 - Ascending UV Micro LED projection display photocuring three-dimensional printing device

[0044] refer to image 3 , different from Embodiment 1, in this embodiment, an ultraviolet Micro LED projection display device is used as an ultraviolet Micro LED projection display device to realize the display of ultraviolet images. The ultraviolet Micro LED projection display device is mainly composed of a display driving circuit, a micro LED array chip and an optical lens group. The ultraviolet image group obtained by the computer system 1a enters the display drive circuit in the ultraviolet Micro LED projection display device 3a after being processed by the controller 2a, and the highly integrated micro LED chips on the micro LED array chip are selectively driven When it is turned on, the ultraviolet light image emitted by the chip is modulated by the optical lens group and finally converges on the molding working surface in the photocuring resin 5a of the materia...

Abstract

The invention discloses a photo-curing three-dimensional printing device based on a UV LED micro-display technology and a printing method of the photo-curing three-dimensional printing device. The photo-curing three-dimensional printing device comprises a computer system, a controller, a UV LED micro-display device, a trough, a forming table and a lifting device. According to the device, slice images obtained by the computer system directly are transmitted to the UV LED micro-display device or a projection display device through the controller, so that corresponding UV images are formed from the slice images on a printing work surface of the trough, thin layer structures of corresponding images are obtained through curing forming of photo-cured resin in the trough under irradiation of the UV images and are accumulated through the lifting device, and a photo-curing three-dimensional printing product is obtained. The UV LED micro-display device is taken as a photo-curing light source, rapid three-dimensional forming of the photo-cured resin is realized, resolution and printing precision are improved effectively, power consumption is reduced, productivity is improved, and the device has certain industrial utilization value.

Description

technical field [0001] The invention relates to the field of three-dimensional printing rapid prototyping, in particular to a light-curing three-dimensional printing device based on ultraviolet LED micro-display technology and a printing method thereof. Background technique [0002] As a kind of rapid prototyping technology, 3D printing is widely used to manufacture models in mold manufacturing, industrial design and other fields, and is now gradually being used for direct manufacturing of some products. 3D printing technology is becoming more and more popular, and the requirements for printing technology are getting higher and higher. [0003] SLA photocuring is the earliest practical rapid prototyping technology. It adopts point forming or line forming. The photosensitive resin is cured by scanning the working surface point by point according to a certain movement path with the laser beam. The photosensitive resin is formed from the point Start curing and then solidify to...
