The rheological properties of printing pastes are crucial for achieving high-quality prints. Sodium alginate, carboxymethyl cellulose (CMC), and xanthan gum (CMS) are commonly used as thickeners and stabilizers in these formulations due to their unique viscoelastic responses.
Sodium alginate exhibits a thixotropic tendency, meaning its viscosity decreases with applied shear stress, which is beneficial for printability. CMC possesses pseudoplastic features, where the viscosity decreases with increasing shear rate, enabling smooth extrusion and controlled ink flow. Xanthan gum demonstrates a strong gel-forming potential at low concentrations, contributing to the structural integrity of the printing paste. The selection of these polymers and their concentrations significantly influence the rheological profile of the printing paste, ultimately impacting print resolution, surface smoothness, and overall print quality.
