Description of the drawings
Fig. 1 is the present embodiment high accuracy 3D printing device three-dimensional structure diagram.
Specific embodiment
As shown in figure 1, a kind of high accuracy 3D printing device, including pedestal 1, exposure mechanism 2 in pedestal 1, control are arranged on
Mechanism processed 3, and the printing mechanism 4 that is arranged on pedestal 1 and Sheng Ye mechanisms 5.Wherein, the printing mechanism 4 include module 41,
The print platform 42 being slidably mounted on module 41, the Sheng Ye mechanisms 5 are included for holding the material trough 51 of printing solution, institute
It is fully transparent or the transparent base plate in subregion to state 51 bottom of material trough, and the impact faces plate 11 offers a through hole,
According to the disengaging mode different from 51 bottom of material trough of print platform 42, pedestal upper table is fixed or be movably arranged on to material trough 51
In 11 through hole of face, material trough 51 can be for square or circular, and the material trough 51 described in the present embodiment is square, and is fixedly mounted
Pedestal upper surface 11.The exposure mechanism 2 adopts LCD display device, the LCD display 21 of the LCD display device（Expose
Mouthful）Below material trough 51 and corresponding with print platform 42, the light of the transmitting of LCD display 21 passes through transparent material trough
51 bottom direct projection print platforms 42.
In the present embodiment, the LCD display 21 is fixedly mounted in base bottom, and parallel with print platform 22 is set
Put.Depending on the size of the article that LCD display can be printed as needed.
The module 41 is provided with a longitudinal leadscrew 411, and print platform 42 is connected with leading screw 411, and leading screw 411 is electric with leading screw
