To evaluate the quality of DIW printing, we compare the mechanical properties of the printed tensile bars to their molded counterparts. The printed specimens exhibit tensile moduli of 652.5 kPa and 89.7 kPa for 𝜆 = 0.25 and 𝜆 = 0, respectively (Fig. , Table ). The tensile moduli are lower than the cast specimens, likely attributed to the imperfect welding between neighboring filaments, a caveat common to filament based DIW printing . As expected, introducing associative groups significantly enhances the mechanical properties of printed tensile bars, increasing the tensile breaking strain from 1.15 to 1.25 and the tensile strength from 239 kPa to 1190 kPa with the corresponding tensile toughness increasing from 132 to 939 kJ/m 3 .
