E-jet printing is a micro/nano-manufacturing process that uses an electric field to induce fluid jet printing through micro/nano-scale nozzles.
TONG LI’s 3D Electrohydrodynamic Printing Machine can be used for printing micron & sub-micron scale droplets by using a wide variety of inks, it has the ability to directly pattern biological materials for biosensors, drop-on-demand functionality for chemical mixing and sensor fabrication, and high-resolution printing for printed electronics.

- Hundreds polymers, metal & oxides, biological materials, and others can be used.
- Normal needles:All standard needles can be used.
- Micro-needles: All sizes between ø1~100µm can be made and supplied.
- High precision X-Y-Z 3D moving stage. (100nm resolution)
- Can Print dots, lines with ø100nm~40µm.
- Fast Continuous Printing.
- Drop on Demand (DOD) Fast Printing.
- Online Microscope Vision System
