Problems solved by technology

[0003] At present, the relatively mature process of 3D printing is to use the stereolithography forming method SLA to solidify the liquid photosensitive material. SLA is the earliest practical rapid prototyping technology. It uses liquid photosensitive resin raw materials. Due to the shrinkage during the curing process of the resin, it is inevitable to generate profit or cause deformation, so precise control of liquid forming equipment is required

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0026] see Figure 1 to Figure 6 , a new type of ultraviolet light curing device for 3D printing devices, consisting of a liquid photosensitive material nozzle 1, an ultraviolet light generator 2, a gas nozzle 3, a nozzle connecting block 4, a support frame 5, a three-axis mobile platform 6, an exhaust system 7, The printing platform 8 and the liquid receiving box 9 are composed. The liquid photosensitive material nozzle 1, the ultraviolet light generator 2, and the gas nozzle 3 are installed on the nozzle connecting block 4, and the nozzle connecting block 4 is driven by a three-axis moving platform 6 to realize movement in three-dimensional space. The liquid photosensitive material spray head 1 sprays the liquid photosensitive material on the printing platform 8 according to a prescribed path. While spraying, the ultraviolet light generator 2 irradiates ultraviolet...

Abstract

The invention discloses an ultraviolet curing device and method for a 3D printer. The device comprises a closed type supporting frame, a printing platform is arranged at the bottom of the inner side of the supporting frame, and a three-axis moving platform is connected to the inner wall of the supporting frame and a nozzle connecting block. The bottom of the nozzle connecting block is connected toa liquid photosensitive material nozzle used for spraying a liquid photosensitive material to the printing platform, a gas nozzle used for blowing gas between layers of the liquid photosensitive material and an ultraviolet light generator used for emitting ultraviolet light to the liquid photosensitive material to solidify the liquid photosensitive material. Marks between the layers can be reduced to the minimum extent, and the appearance of parts is improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to an ultraviolet curing device and method for a 3D printer. Background technique [0002] 3D printing is a form of additive manufacturing technology in which three-dimensional objects are created through successive physical layers. Compared with other additive manufacturing technologies, 3D printers have the advantages of fast speed, low price, and high ease of use. A 3D printer is a device that can "print" a real 3D object. It is functionally the same as the laser forming technology. It adopts layered processing and superposition forming, that is, it generates a 3D entity by adding materials layer by layer, which is different from the previous removal of materials. Processing techniques are completely different. [0003] At present, the relatively mature process of 3D printing is to use the stereolithography forming method SLA to solidify the liquid photosensitiv...
