“3D and 4D printing of tough hydrogel materials” – Presented by Marc in het Panhuis, University of Wollongong

Hydrogels are smart and multifunctional materials with a real potential for use in a variety of novel applications including soft robotics, (edible) sensors and bionic implants. Consisting of a highly swollen polymer network, hydrogels are typically soft and brittle which means that they are not compatible with many traditional techniques used to process raw materials into useful structures. In this presentation I will demonstrate a variety of (extrusion-based) 3D and 4D printing techniques for processing hydrogel inks alongside other inks of structural polymers to create a range of composite architectures including a smart valve, an artificial cartilage meniscus, an artificial tendon, brain-like structures and edible electronic circuits.
