2nd Place – 3D-Printed Copper or Air? Adam Jakus

This 3D-printed copper salt structure can be used in many ways. Here, it floats in a jar of water. The water dissolves the copper salt, resulting in a blue color, and transforming the structure into a very porous sponge-like material. When the salt has been completely dissolved, a polymer skeleton remains. This skeleton resembles the original 3D-printed shape but is incredibly light, like air.

Creating materials like these is important because the “polymer skeletons sponge” can be used to implant all kinds of potent gel and liquid biomaterials during surgery. These fragile gels are currently being used to regenerate parts of tissues and organs.
