Embodiment 1

[0025] See figure 1 , figure 1 It is a schematic diagram of the overall structure of a device for 3D printing provided by an embodiment of the present invention. The embodiment of the present invention provides a device for 3D printing. The device for 3D printing includes a moving platform 100, an insulating board 200, a refrigerating board 300, an ultra-low temperature control cabinet 400, and an electrostatic high voltage power supply 500. The following detailed descriptions are made for the movement platform 100, the insulation board 200, the refrigeration board 300, the ultra-low temperature control cabinet 400 and the electrostatic high voltage electricity respectively:

[0026] For the sports platform 100:

[0027] The movement platform 100 may be provided with a printing needle 110 and a stage 120. Wherein, the repeat positioning accuracy of the moving platform 100 is 2 microns; the material of the printing needle 110 is metal. The distance between the printing needle 110 ...

Embodiment 2

[0051] See figure 2 As shown, figure 2 It is a flowchart of a method for 3D printing provided by an embodiment of the present invention. The second embodiment of the present invention provides a method for 3D printing, and the method for 3D printing includes:

[0052] Step S100, when the temperature is 20°C to 22°C, the polymer solution is prepared.

[0053] Please continue to see figure 2 , You can adjust the ambient temperature from 20°C to 22°C to configure the polymer solution to be printed. The polymer solution may refer to a true solution formed by dissolving a polymer in a small molecule solvent.

[0054] In step S200, the refrigerating liquid is delivered to the refrigerating plate 300 through the ultra-low temperature control cabinet 400 to reduce the temperature of the refrigerating plate 300.

[0055] Please continue to see figure 2 By opening the ultra-low temperature control cabinet 400, the temperature of the ultra-low temperature control cabinet 400 can be set ...
