Effect of particle shape on rheology and printability of highly filled reactive inks for direct ink writing
Progress in Additive Manufacturing

Volume 8, Pages 1573–1585
Highly filled inks including a reactive titanium–boron composite powder (with Ti·2B composition), a polymeric binder, and a solvent mixture combining the main solvent with a plasticizer and surfactant, are prepared for material extrusion-based printing. To determine the effect of particle shape and loading on rheology and printability of the inks, both spherical and irregularly shaped powders with the same composition and close particle sizes are manufactured by high-energy milling and used to formulate 80%, 90%, and 95% (wt.) inks. All ink formulations show shear thinning and shear recovery behavior. The degree of shear thinning decreases with increased particle loading, and…
