The Xaar 128 is a piezoelectric inkjet printhead used in large format vinyl sign-making. It might be useful in 3d printing, conductive ink, or masking applications. This guide is intended to help others experiment with the Xaar 128 and different materials in hopes that they’ll share their results.
Why piezo? TLDR: Most inkjet printheads are “bubble jet”: They work by superheating a fraction of the ink in a chamber, turning it into gas, which expands to force the remainder of the ink out of a nozzle. Superheating limits the range of materials that can be used in these printheads. Piezoelectric printheads are less common, and since they use a mechanical operation to force fluid out of a nozzle, they don’t have to modify the state of the fluid to operate, and can work with a broader range of materials.
Xaar approved inks have viscosity around 0-12cps. Higher viscosity fluids are unlikely to work with this printhead.
