Exploiting the temperature-memory effect in 3D printed auxetic structures

Stefano Pandini

from experimental design to analytic simulation.

The combined employ of the additive manufacturing approach with shape memory polymers (SMPs) is one of the possible strategies towards 4D-printing, in particular when aiming at the realization of highly effective shape shifting objects. SMPs are in fact active systems, capable of being temporarily fixed in a deformed configuration and to revert to the pristine shape upon application of a thermal stimulus. In addition, this response may be finely tuned by a proper combination of the thermo-mechanical history and of the material macromolecular architecture.

A duo presentation by Frederic Demoly, Associate Professor at Université Bourgogne Franche-Comté, UTBM and Jean-Claude Andre, CNRS.

Over the past decades, the combination of technical/scientific advances in additive manufacturing (AM) and smart materials (SMs) domains has enabled the booming development of a new interdisciplinary converging research area: 4D printing.
