Description
technical field [0001] The invention relates to a method for preparing a full-jet printing multi-nozzle nozzle. Background technique [0002] 3D printing directly uses the three-dimensional model designed by the computer, without the need for tools and molds, and quickly realizes the manufacture of complex parts through the layered discrete and accumulation process from point to line, from line to surface, and from surface to volume. The British "Economist" magazine believes that 3D printing technology, together with other digital production models, will promote and realize the third industrial revolution. At present, the main component of 3D printing technology is the multi-nozzle nozzle, which is mainly formed by mold injection. However, the complex process of mold opening in the molding process is not conducive to reducing the development cost and development cycle of the multi-nozzle nozzle. Electrospinning jet printing and electromagnetic drive jet printing technology ...
