Technologies
This project focuses on research of temperature field auxiliary piezoelectric printhead used for droplets spray additive manufacturing technology, in special, to develop print head for polymer materials, to provide common technology support and key components for polymer molding, sand mold casting, and three-dimensional electronic devices etc.
Features:
The project will develop piezoelectric droplet spray printhead system with high performance and features as follows:
High frequency continuous operation
Permits high viscosity jetting fluids
Multi-ink compatibility
Robust design and high speed operation
Single head can be easily configured to make a print bar of any width
Optional temperature control
Key technologies:
The key challenge this project is to know fluid-structure coupling characteristics of fluid inside the piezoelectric driven micro cavity and obtain controlling method and injection mechanism of the fluid.
Optimization design method of printhead structure
Printhead MEMS structure manufacturing and integration
Printhead driven and control
Precise control of droplets injection of printhead
Printhead performance assessment
