Device and method for achieving high-precision 3D printing through saline solution

Abstract

The invention belongs to the technical field of 3D printing, and particularly relates to a device and method for achieving high-precision 3D printing through a saline solution. The device comprises areceiving platform system. A conductance cell is arranged in the receiving platform system. A printing platform is arranged at the upper end of the receiving platform system. A laser range finder is arranged at the left end of the surface of the printing platform, and the rear end of the receiving platform system is connected with a wire. Through the arrangement of the conductance cell and a high-voltage electrostatic generator, the voltage is turned on to be adjusted to -5 kV, and products are printed on the printing platform; through the arrangement of the receiving platform system, after printing of one layer, the receiving platform system 7 controls the printing platform to move downwards in the axis Z; through the arrangement of the laser range finder, when the receiving platform system moves, the liquid face is controlled after the laser range finder detects level face feedback, and it is guaranteed that the liquid face is flushed with the height of the upper layers of the printing products; and operation is repeated in sequence, the printed products with the height being 2 cm are obtained finally, and the diameter of a single fiber is 20 micrometers.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional printing, and in particular relates to a device and method for high-precision three-dimensional printing using saline solution. Background technique [0002] Traditional 3D printing technology can obtain micron-scale fibers with low precision, but due to the combination with computer technology, the structural shape can be controlled; electrospinning is the main method for preparing nanofibers, and the resulting fibers are fine and high-precision, but it is not possible. control; high-precision 3D printing can be achieved by combining the two. It has better expanded the application of 3D printing technology, especially in the fields of medical devices, tissue engineering scaffolds, and tissues and organs. [0003] The combination of electrospinning and 3D printing can improve printing accuracy and reduce the diameter of a single printing fiber to 1-150 μm. However, this method of using...
