Fundamentals of 4D Printing andSmartMaterials

To understand the marine potentials, it i s necessary that material science underpinning 4D printing. The technology relies on programmable materials - a class of substances that exhibit predistable, reversible, or irreversible changes wheen exposed two specific external triggers. These materials are combined with precise sational control during printing to create anisotropic structures with embedded actuation patways.

Hydrogels andd Moisture- Responsive Materials

Hydrogels are croslinked polymer networks thatt svell signitantly in water. When printed with spatially varying croslink density, they can bend, twist, or fold upon hydration. For marine applications, this enables structures that change a shape with vitdal cycles or dept.h - for example, a mooring line that stistengens in shallow water and becomes more compleant in deper zons.
