Figure 1.

Loop flow curve of a 45 wt% boehmite suspension aged for 8 h. This protocol replicates the shear applied on a printed ink, from the syringe to the printing support. While measuring $\dot{\gamma }$, an increasing stress controlled ramp was applied (1) until suspension yields at the ${\sigma }_y^{Stat}$ (2). When $\dot{\gamma }$ exceeded 100 s ⁻¹ (3), a decreasing shear rate controlled ramp was applied until $\dot{\gamma }=1s^{-1}$ and stress relaxes at ${\sigma }_y^{Dyn}$ value (4).
