Shape Memory Metamaterials by 4D Printing Technology

A presentation by Mahdi Bodaghi, Nottingham Trent University.

Recent advances in AM created 4D printing technology as an emerging technology for crafting meta-materials and smart devices that can change their shape and/or function on-demand and over time.

This technique provides an effective means from idea to reality with performance-driven functionality built into materials. 4D printed smart structures have great potential in mechanical/biomedical applications like structural/dynamical switches, self-conforming substrates, self-tightening surgical sutures, self-conforming splints, self-coiling/deploying stents, rolling-up chiral metamaterials, load-resistance supportive auxetics, etc.

The 4D printing approach is based on a rigorous understanding of the complex thermo-mechanics of smart materials and experiments to determine the printed material properties and adaptive motions in terms of relevant microstructural parameters as well as theory and simulation to describe the phenomena. In this talk, related research projects and key results will be presented related to shape memory.
