As a rapid additive manufacturing printing technology, flexible electronic micro-injection 3D printing technology has many advantages such as non-contact, high deposition accuracy, wide range of ink materials and controllable precision. It is becoming an ideal manufacturing technology for flexible circuit board, solar cell, thin film transistor, micro sensor, electronic skin and other precision electronic components. It can realize the additive manufacturing of many functional materials including metal, conductor, insulator and composite materials. Due to the non-contact mode and the height control between the nozzle and the substrate of 10 to 15mm, it can adapt to the printing of complex curved surface including curved surface. The multi-nozzle array structure can realize the printing and packaging of flexible electronic equipment at one time, which solves the problem of multi-process equipment in the traditional manufacturing process. The self-developed printing system can generate and process the line graphics generated by the user through the standard CAD software, and then transport the ink made of materials through the transport of nitrogen through the particle filter to the nozzle through the pneumatic atomization and ultrasonic physicalization, and then deposit on the surface of the substrate material after being constrained by the surrounding gas. After laser sintering and baking of the substrate, the droplet particles are bonded to improve its related electrochemical performance. Finally, the ultra-fine line width pattern with a line width of less than 10um can be generated on the surface of the substrate. The printing process can not only realize the automatic control of the process, but also through the machine vision system real-time monitoring of the printing process, can be printed in glass, ceramic, paper and a variety of materials surface complex structure, can be widely used in the surface spraying, micro structure, micro sensor, flexible electronics, new energy, optical manufacturing, biomedicine and other fields.
