Printing a Metallic Spider

Caption

Researchers have developed a metallic gel that is highly electrically conductive and can be used to print three-dimensional (3D) solid objects at room temperature. Printed objects can be engineered to change shape as the gel dries; a phenomenon called '4D printing,' with the fourth dimension being time. This image shows a metallic spider that was printed at room temperature using the metallic gel, and which assembled and solidified into its final 3D shape via 4D printing.
