Abstract

The invention belongs to the technical field of inkjet printing micro-manufacturing, and discloses an ink droplet border aligning optimizing method for nano silver inkjet printing and a printer. The ink droplet boarder aligning optimizing method includes the steps that a relationship equation of the negative pressure and the ink droplet distance is obtained by fitting according to measuring the relationship between negative pressure values of different piezoelectric nozzles and the radius of a jetted nano silver ink droplet; a to-be-printed part in a printing model of the model surface is determined in a computer, and the to-be-printed part is separated and stored in a STL format; a beginning printing start coordinate and the printing interval length are calculated according to a G code provided with a jet interval command, the ink droplet radius supplementation is conducted on the printing length according to the radius of the ink droplet, and the ink droplet radius is stored in printing length variable values; the ink droplet distance in the printing process is determined according to the optimized printing length and the ink droplet radius, and the ink droplet falling point initial planning is conducted; a conductive figure surface is printed; and execution of all execution codes is completed, and a conductive figure is obtained. According to different base materials, the negative pressure is adjusted so as to change the size of the ink droplet to adapt to the base materials, and thus the uniformity of the border of the conductive figure is improved effectively.

Description

technical field [0001] The invention belongs to the technical field of ink-jet printing micro-manufacturing, and in particular relates to a method for optimizing the boundary alignment of ink droplets in nano-silver ink-jet printing and a printer. Background technique [0002] The 3D printing technology is based on the computer 3D design model. Through the software layered discrete and numerical control forming system, the metal powder, ceramic powder, plastic, cell tissue and other special materials are accumulated and bonded layer by layer by means of laser beams and hot melt nozzles. The final superimposed molding creates a physical product. 3D printing technology has achieved a certain level in reconstructing the geometry and function of objects, and almost any static shape can be printed. The digital manufacturing mode does not require complex processes, huge machine tools, or a lot of manpower. Parts of any shape can be generated directly from computer graphics data, ...
