The aim of this project is to establish the link between fabrication protocols and mechanical gradients, in model soft solids. The fabrication method will rely on layering, a technique at the basis of 3D printing, and the characterization on micromechanics experiments, which allow for the visualization of materials displacements in the three spatial directions. Beyond opening new ways to design and control soft solids, this project will have far-reaching fundamental implications in the fields of multiphasic materials, 3D printing, and polymer physics.
