Other Applications:
This printhead family can also be used to print fluids used in the Advanced Manufacturing and 3D market sectors. The piezo inkjet technology used in these printheads is capable of printing fluids with a range of viscosity, reactivity and conductivity. Xaar can support you in choosing the right printhead for the fluid type and for the application vs. the performance specification and price.
