Abstract

Thixotropy, a time-dependent shear-thinning behavior, contributes to the flow and shape retention characteristics of inks used in extrusion-based 3D printing. This study investigates the effect of the thixotropic behavior of sodium Carboxymethyl cellulose (Na-CMC) solutions at varying concentrations on parameters crucial to 3D printing, using comprehensive rheological tests, including flow curves, rheograms, and three-interval thixotropy tests (3ITT), and the influence of temperature. The 3ITT demonstrates 100% recovery for a 1% CMC concentration and optimal printability at a 2% CMC concentration. This research demonstrates that the key rheological parameters of thixotropic fluid correlate with extrusion-based printing as well as techniques for determining printability.
