At room temperature, these two polymers exhibit shear moduli of 48 kPa and 375 kPa, respectively (Fig. ). An end block volume fraction of 0.31 is close to the highest value explored in this study (Table ) and corresponds to the LAL polymer possessing the strongest glassy domains which provides the greatest challenge for extrusion. Despite possessing strong glassy domains, the LAL polymer readily exhibits a yield-stress behavior at 170 °C (Fig. ). The measured yield stresses of 829 Pa (𝜆 = 0.25) and 459 Pa (𝜆 = 0) are low enough that the material can be readily extruded but high enough that the material will retain it's as-deposited shape. As the material cools after exiting the nozzle, the glassy domains will reform to further increase the material strength. This yield-stress behavior makes the material suitable for high-temperature DIW printing (Fig. ).
