This study aims to design and 3D print porous elements for soft robotic applications and test the stiffness
changes when the cavities are filled with liquids. When an elastic element has porous scaffolds, the
stiffness can be controlled by filling the cavities with a liquid. A gyroid structure is selected for the
design and evaluation of the characteristics of elements. The stiffness of the element in both non-filled
and liquid-filled modes is analyzed using Finite Element Model (FEM) simulation Software in two
modes where simple support with central loading and compressive uniform loading. A porous test
structure is created and tested in these modes for observation of the stiffness change. In this project,
employing a Fused Deposition Modelling (FDM) printer enabled us to make our thoughts into reality.
The results show that liquid-filling can be used as a stiffening method for porous scaffolds in soft robotic
applications
