Standing tall for more than 120 years, it is hard to find anyone who doesn’t recognize the Eiffel Tower. It’s a symbol of love, awe, and lately, 3D printing. When Gustave Eiffel first set eyes on Mauric Koechlin and Emile Nouguier’s original design, he probably didn’t realize that this epoch of engineering would later be reproduced in a spectrum of bright colors and far-fetched materials –let alone that 3D printing would even exist one day.
