Problems solved by technology

However, the printing resolution of droplet jet printing technologies such as piezoelectric, ultrasonic, and thermal bubbles is strongly dependent on the size of the orifice. Orifice clogged
Therefore, it is difficult to realize the printing and manufacturing of 3D structures at the micro-nano scale by relying on piezoelectric, ultrasonic, thermal bubble, etc. droplet jet printing technology, which limits its application in 3D M / NEMS devices.

Abstract

The invention belongs to the technical field of advanced manufacturing, and relates to an electrojet 3D printing device and method based on the combination of an electric field and a heat field. According to the method, in the process of electrojet 3D micro-nano printing under the combined action of the electric field and the heat field, ink reaches an opening of a spray needle at the constant flow speed under the combined action of the fluid field and the gravity field, then the ink is drawn through electric field shear force between the spray needle and a substrate so as to form stable micro-nano flow with the size far smaller than the size of a spray hole, a solvent in the ink is promoted to evaporate in an accelerated mode through the heat radiation effect of the heat field on the ink, and finally jet flow is stacked on the substrate layer by layer, so that a 3D structure with the micro-nano dimension is formed. Compared with a drop-jet type printing technique, the electrojet 3D printing method based on the combination of the electric field and the heat field has the advantages that the material adaptability is high, and complex micro-nano 3D structures can be manufactured.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology, and relates to an electrospray 3D printing device and method based on electric field-thermal field compounding. Background technique [0002] 3D printing is an advanced manufacturing technology that has developed rapidly in recent years. Compared with traditional "removal" manufacturing technology, it can quickly and precisely manufacture parts with complex shapes, reduce processing procedures, and shorten processing cycles. It has broad application prospects in fields such as medical treatment and electronic information. [0003] M / NEMS devices have developed from a flat, single structure to a 3D, complex, flexible structure, and the manufacturing process is as simple as possible. 3D printing can realize rapid manufacturing of arbitrary design structures, and can meet the needs of M / NEMS devices for complex, 3D, and flexible structures. In printing technology, liquid jet printi...
