This characteristic is desirable for 3D printing modalities, as materials with a low flow behavior index can better adapt to the flow requirements of the nozzle without excessive force. The consistency coefficient ( 𝒌𝒌 ), reflecting slurry thickness, also increased with microparticle addition (Figure ), contributing to structural integrity in printed forms by providing higher viscosity at low shear rates. Yield stress values, which became measurable at microparticle concentrations above 70%, suggest the slurry's ability to withstand deformation until a critical stress threshold is met, which is crucial for embedded printing where the material must support subsequent layers. This rheological property allows for printing complex, unsupported structures, enhancing stability in 3D printed constructs. Hydrogel formulations with higher absorbance and lower transmittance are likely to support rapid UV curing and higher crosslinking densities, enhancing mechanical stability.
