One kind of dropping photocuring type printing system and method to follow

The present invention discloses a dropping printing systems and methods follow photocuring, the mobile platform comprises a two-dimensional, the substrate, the light source, a focusing lens, the photo-curable liquid supply system, the solenoid valve nozzle, the solenoid valve for control of head , and a drive for moving the substrate in the vertical direction one-dimensional mobile platform; substrate fixed to the one-dimensional mobile platform, a light source, a focusing lens, and the solenoid valve nozzle fixed to the two-dimensional movement on the platform, the light emitted from the light source after the focus lens is focused spot formed on a substrate is positioned, the light spot is located a solenoid valve nozzle liquid inlet and the liquid outlet photocurable directly below the liquid supply system, the solenoid valve of the liquid outlet nozzle in communication; light emitted from a light source the wavelength of the light curable liquid supply system, liquid curing the photocurable desired wavelength of light is the same. The present invention enables accurate positioning of cells and the photocurable liquid within the three-dimensional space, and to ensure that material is not contaminated, while saving material.
