Embodiment 1

[0031] Such as figure 1 As shown, a rapid 3D printing device includes a base 1, an exposure mechanism 2 arranged in the base 1, a control mechanism 3, a printing mechanism 4 and a liquid holding mechanism 5 arranged on the base 1, wherein the The printing mechanism 4 includes a module 41 and a printing platform 42 slidably installed on the module 41. In this embodiment, the printing platform 42 slides up and down through a screw 43 vertically arranged on the module 41. The printing platform 42 is connected with the lead screw 43, and the lead screw 43 is connected with the lead screw motor. The lead screw 43 is driven to rotate by the lead screw motor, and then drives the printing platform 42 to move. During the printing process, the printing platform can rise at a constant speed. The control mechanism 3 is controlled by a microprocessor, and the control mechanism is respectively connected with the exposure mechanism 2, the printing mechanism 3 and the liquid holding mechanism...

Embodiment 2

[0040]The structure of the fast 3D printing device described in this embodiment is consistent with that of Embodiment 1, the main difference is that in this embodiment, in the fast printing method of the 3D printing device in the curing process described in step 2, the printing platform 42 pauses for 0.5 seconds and then Rising at a constant speed, the material tank 51 stops at a constant speed for 0.5 seconds and then rotates at a constant speed. The pause time of the printing platform 42 and the material tank 51 is generally determined according to the cross section of the printed item (that is, the area of ​​the solidified layer) and the curing time of the printing solution. Generally, the printing platform stops for 0.1S-1S, and the material tank stops for 0.2S-1S. When the area of ​​the solidified layer is small and the printing solution is solidified quickly, the printing platform 42 and the material tank 51 can move at a constant speed without stopping to realize fast pr...

Embodiment 3

[0042] The structure of the fast 3D printing device described in this embodiment is basically the same as that of Embodiment 1, the main difference is that the exposure mechanism 2 described in this embodiment adopts an LCD display device, and the LCD display screen of the LCD display device is located in the material tank as the exposure port. below. The curing principle of the LCD display device: using the LCD display imaging principle, driven by the LCD display device, a selective transparent area appears on the LCD display according to the printed image, and under the irradiation of the ultraviolet light source of the LCD display device, the LCD display The transparent area of ​​the image has reduced UV blocking, and in the area where no image is displayed, the UV light is blocked. The ultraviolet light passing through the LCD display screen forms the ultraviolet light image area, and the above ultraviolet light is irradiated to the printing solution through the transparen...

Abstract

The invention discloses a quick 3D printing device and a quick printing method. The device comprises a base, an exposure mechanism, a control mechanism, a printing mechanism and a liquid containing mechanism, wherein the exposure mechanism and the control mechanism are arranged in the base; the printing mechanism and the liquid containing mechanism are arranged on the base; the printing mechanism comprises a module and a printing platform slidably mounted on the module; the liquid containing mechanism comprises a material tank used for containing a printing solution and a driving assembly used for driving the material tank to rotate; the bottom of the material tank is provided with a completely transparent bottom plate or a partially transparent bottom plate; the bottom plate is covered with a layer of transparent liquid film with the uniform thickness; an exposure port of the exposure mechanism corresponds to the printing platform and used for allowing exposure curing light to pass through the transparent material tank bottom and be directly irradiated onto the printing platform. The quick 3D printing device and the quick printing method provided by the invention has the characteristics that the printing speed is high, the precision is high, the service life is long, the size is small, and operation is easy.

Description

technical field [0001] The invention relates to a fast 3D printing device and a fast printing method, belonging to the technical field of printing equipment. Background technique [0002] A 3D printing device, also known as a three-dimensional printer, is a machine that uses cumulative manufacturing technology (that is, rapid prototyping technology). Its principle is to put data and raw materials into a 3D printer, and the machine builds products layer by layer according to the program. At present, during the printing process of conventional 3D printing devices, when the solidified layer of the printing platform is cured, the printing platform needs to be raised to separate the surface of the solidified layer from the bottom of the printing solution container, and then descended again to expose and cure the second layer. The repeated rise and fall of the printing platform accounts for 80% or more of the entire printing process, which eventually leads to slow printing speed a...
