Abstract
Stability is an essential property of suspensions for material jetting. By adjusting the suspensions’ stability, they are useable for a more extended period without losing its functionality in the printing process. Stability can be analyzed either by the determination of the zeta potential or sedimentation tests. Both methods were carried out for aqueous carbon black suspensions, mixed with different additives. It was found that both methods of analysis can be correlated. Furthermore, the addition of a kind of stabilizer, like BYK-420, is necessary to generate a stable carbon suspension.
