A bridge inspired by a design sketched by Leonardo da Vinci more than 500 years ago has been brought to life as a modern prototype using 3D printing and waste from stone processing. WASP and the Polytechnic University of Bari said, the project team describes Da Vinci's Bridge as the first 3D-printed bridge to use waste materials from stone processing , combining additive manufacturing with Leonardo's original vision for a self-supporting structure. The project was conceived by Professor Giuseppe Fallacara of the Polytechnic University of Bari and draws on Leonardo's design for a bridge that would have connected the Pera district, present-day Galata in Beyoğlu, with Constantinople, today's Istanbul, across the Golden Horn. The prototype is a pedestrian bridge with a span of approximately 6 metres and adapts Leonardo's concept for the needs of the experiment.
