Laser auxiliary electric jetting in-situ printing manufacturing method

Abstract

The invention belongs to the technical field of advanced manufacturing, and provides a laser auxiliary electric jetting in-situ printing manufacturing method. A functional material ink flows out froma spraying needle port under the action of pressure, and due to the action of the electrohydrodynamics effect, a stable Taylor cone is formed to jet out stable fine jet flow to a base body to form a printing layer. Meanwhile, a laser energy device is used for carrying out composite processing on the printing layer, emitting laser beams and irradiating the printing layer according to printing tracks, and high-temperature curing, crystallization and other functional processing on a printing structure can be synchronously realized in situ. According to the method, functional structures and devices are directly realized on the base body in situ, the problem of secondary positioning errors of transferring, gluing, splicing and the like in a traditional method is eliminated, the problems that binding force is weak, and sensitivity is low due to a gluing process are avoided, and the feature size of a functional unit can be reduced by means of the high-resolution printing advantage of electricjetting; and the size precision and the bonding strength of a printing unit structure are improved, so that the sensitivity and the stability of the devices are improved.
