Printing Optimization - Cellink BIO X EMD User Manual

4.9 Printing optimization

The EMD Printhead uses an electromagnetically actuated valve to form droplets in the micro- and nanoliter range.
Pressurized fluid can flow when the valve is open, and the flow stops when it is closed. An optimal nozzle diameter,
valve travel speed and actuation yield the minimal dispensing volume. The BIO X allows the user to enter the open time
and the cycle time.
Due to the technique used to form the droplets, this printhead might be incompatible with highly viscous materials.
However, adding heat to thermosensitive materials can lower the viscosity enough to make them compatible. Larger
nozzle diameters and valve travel are recommended when using larger flow volumes and high-viscosity fluids, while
smaller diameters with smaller valve travel are recommended when using small dispensing volumes and low-viscosity
fluids.
