EPJet: Greyscal Printhead Technology

EPjet is a novel drop-on-demand printing technology, which was developed with the target to print highly viscous paints and varnishes, which may also have pigments and fillers (patent pending).

 

Working principle:

A micro-pneumatic control unit generates multiple pneumatic control signals by an internal fast-switching microvalve-array. The pneumatic signals are used to control fluid droplet ejection through drop-on-demand nozzles included in a fluidic unit. The fluidic unit is configured as a low cost component out of plastic material, which can be easily replaced, if contaminated. Depending on control pressure and nozzle goemetry the drop sizes are controllable in a wide range.

 

Working Range:

- Nozzle diameters 0.1 .. 1mm

- Firing frequency up to 1 kHz (New Generation, up to 3 kHz)

- Fluids of arbitrary chemistry, up to 1 Pas, depending on the individual Application

- Fluids with particles up to 0.1 mm
