Using the principles behind the formation of sandcastles from wet sand, North Carolina State University researchers have achieved 3D printing of flexible and porous silicone rubber structures through a new technique that combines water with solid and liquid forms of silicone into a pasty ink that can be fed through a 3D printer. The finding could have biomedical applications and uses in soft robotics. Orlin Velev and coll

eagues show that, in a water medium, liquid silicone rubber can be used to form bridges between tiny silicone rubber beads to link them together – much as a small amo...
