This rock installation aims to show the potential capabilities of 3D-printing in architecture. Showcased at the Chicago Architecture Biennial, the rock pile is held together only by string, formed entirely by a robotic arm.

The giant rock formation is 13 feet high and made up of loose recyclable "rocks," made from heated and expanded crushed glass. A 3D-printer was implanted with an algorithm so that it would strategically wind the string in a pattern to hold the stones together. The string, made from recycled textiles, measures almost five miles long.

This structure would have been a painstakingly time-consuming and difficult process for humans. However, with a 3D-printer, this recyclable tower could be produced for any building, structure or park easily and efficiently.
