3D printing or additive manufacturing using smart materials has led to the emergence of something called 4D printing. Smart materials are known to react to certain external stimuli such as heat, humidity, pH or changes in electric and magnetic field. Once the object has been printed, it can store (or ‘remember’) its permanent shape; be deformed to another shape and then come back to its initial form by applying the stimulus. This phenomenon is called Shape Memory. In SCION, we developped biobased shape memory composite. In this work, we have been quantifying these performances. Our results are presented in the scientific paper : Quantifying the Shape Memory Performance of a Three-Dimensional-Printed Biobased Polyester/Cellulose Composite Material.
