An in-situ heat treatment device for electrospray three-dimensional printing

Abstract

The invention belongs to the technical field of advanced manufacturing, and relates to an electrospray three-dimensional printing in-situ heat treatment device. An in-situ electrospray printing modulesprays out ink in a stable fine jet mode under the electrofluid power effect, a printing layer is formed, and a base body is printed to be in a needed shape according to track movement. An in-situ heating module carries out rapid high-temperature heat treatment on the printing layer in situ, the liquid-state printing layer is solidified in situ, and organic solvent and stress are removed. An in-situ cooling module rapidly cools a printing flat plate to indoor temperature in situ, and therefore electrospray printing for a next layer is carried out on the solidified printing layer. By means ofthe way that electrospray printing and in-situ heat treatment are carried out in site layer by layer, layer-by-layer printing manufacturing of a micro-nano scale three-dimensional structure is achieved. The technological step of displacement heat treatment is omitted, the precision error caused by realignment in the displacement heat treatment process is avoided, direct in-situ high-precision printing manufacturing of the three-dimensional micro-nano structure is achieved, technological steps are simplified, printing efficiency and quality are improved, and the machining cost is reduced.

Description

Technical field [0001] The invention belongs to the field of advanced manufacturing technology, and specifically relates to an electro-jet three-dimensional printing in-situ heat treatment device. Background technique [0002] Electrojet 3D printing technology uses the electrohydrodynamic effects of liquid fluids to form micro-nano-scale jets and form a printing layer on the substrate. By moving in a predetermined trajectory, various shapes can be printed on the substrate. The printing method can produce three-dimensional microstructures. This technology has the advantages of high resolution, strong controllability, and wide material adaptability, and has broad application prospects in the fields of micro-electromechanical systems, precision devices and other fields. [0003] The fluid materials used in electrojet printing are often liquid fluids. However, due to the fluid flow characteristics, three-dimensional structures cannot be directly formed by layer-by-layer accumulation. ...

AI Technical Summary

Problems solved by technology

Most of the current high-temperature heat treatment methods are to shift the substrate to the heating table, and then put it back to the original position to continue printing after the high-temperature heat treatment is completed. However, this shift heating method has the problem of inaccurate alignment. As a result, the printing position of the next layer deviates from the original position, which reduces the accuracy of the three-dimensional microstructure produced by electrojet printing, and the entire alignment process consumes a lot of time, which affects the printing efficiency
