Design and Implement of a Low Cost Drop-on-Demand Inkjet Printing System

Abstract:

Nowadays, drop-ondemand inkjet printing technology has shown its potential in many fields. This paper presents designing and implementing of a low cost drop-ondemand inkjet printing system. Inkjet printing system can be divided into four parts, and back pressure control system and droplet observation system are two key components, both of which are described in details. In order to have a further control of accuracy and stability of the system, this paper discusses the parameters designed in the system. In pressure control system, the designed system has higher accuracy compared with the Microfabs product. Images can be taken through CCD camera instead of ultra-high-speed camera by using droplet observation system. Some experiments also have been done to verify the feasibility of the device. Accuracy of pressure control, stability of the system and reproducibility of inkjet process can be verified from the experiment.
