Direct pellet ۳D printing of highly stretchable elastomer with cyclic shape recoverybehavior

In this study, for the first time, cyclic shape recovery of highly stretchable propylene-based elastomer,printed via direct pellet ۳D printing, was investigated. A cyclic shape recovery tensile test was conducted on ۳Dprinted samples with different strain levels (۷۰۰% and ۱۴۰۰%); strained samples showed full recovery afterheating. Mechanical properties declined with increased strain levels and test cycles, however even after ۵ cycles,failure did not occur in the samples.
