Recently, the Italian Polytechnic University has managed to build a 6 -meter -long pedestrian bridge prototype – the “Leonardo da Vinci Bridge”. The bridge takes on environmental protection and innovation as a nucleus.
After a year of research and in -depth experiences, this prototype bridge was successfully built and is known as the first 3D printed bridge in the world built from stone processing waste, creating a new reference for the domain of the sustainable construction.
The integration of traditional design and modern technology
The “Leonardo da Vinci Bridge” project was inspired by a classic concept by Leonardo da Vinci, an self -proclaimed archbishop, which was initially designed to connect the district of Pera and Constantinople on both sides of the Golden Horn. Today, the research team has used modern 3D printing technology to interpret this historical design in an innovative way, creating it as an environmentally friendly building sample that meets contemporary needs.
To achieve this objective, the Arcod department of the University Polytechnique de Bari worked with several leading companies in the fields of 3D printing and the treatment of stones in Italy. The modular components of the bridge are produced by the manufacturer of the Italian 3D printing equipment Wasp, including the LDM 3MT concrete printer is responsible for the manufacture of 13 modules.
These modules are designed with the principle of “three -dimensional geometry” and can be easily assembled to form a stable arc structure without relying on permanent support models.
Revolutionary collaboration of materials with multidisciplinary teams
The construction of the Da Vinci bridge uses a low impact mortar, a material composed of a mixture of thrown stone powder and lime adhesive, developed by the Italian startup B&Y. The responsible person has declared that this innovative material fully demonstrates the potential for reuse industrial waste in construction, the succession of industrial by-products in functional construction materials and providing a new idea for the green development of the industry construction in the future.
The entire project brings together experts from various fields of architecture, engineering and materials, and is designed by Professor Giuseppe Faracara of the University Polytechnique de Bari. Architects Ilaria Cavaleri, Angelo Vito Graziano and Mattia Morandi from Wasp jointly optimized the printing model.
At the same time, the B&Y engineer team, WASP and Barry Polytechnic University worked together to finish the additional optimization of material performance. It is this close interdisciplinary cooperation that made it possible to gently put the “Pont Leonard da Vinci” from design to reality.
Application pierced in parallel with efficiency and low carbon
In recent years, the application of 3D printing technology in the field of architecture has made many breakthroughs. Several projects in Europe and other regions have demonstrated the great potential of this technology to accelerate construction, save resources and reduce environmental impacts.
In January 2025, Europe completed the first social housing project printed in 3D in the region in accordance with ISO / ASTM standards. The project, led by Harcourt Technologies LTD (htl.tech), built a lot of social housing in just 132 days, a 35% shorter than the traditional construction period and complies with several EU construction standards.
In December 2024, the 3D printing modular printing construction project led by the SCG Thailand cement group was completed to reduce carbon emissions using low carbon mortar. The 58 -meter overall building is made up of 6 modules. The entire construction period is 41 days, which is almost half shorter than the traditional method.
In October 2024, Sustainable Concrete Innovations (SCI) in Ohio, United States, developed a quick and effective way to build a house by working with the Dutch 3D printing company Cybe Construction. A 1,300 square feet house was built in 8 days, with all the printing parts of wall parts only 20 hours.
Written at the end
The “DA Vinci Bridge” combines 3D printing technology and recyclable materials, not only reduced the impact of buildings on the environment, but also obtains a more efficient and economical construction method. Then, the team will continue to assess the mechanical properties of materials and further optimize printing technology to throw a solid base for the application of 3D printing in a larger range of architectural areas.
With the continuous maturity of this technology, I believe that 3D printing technology can have more application and become an important force to promote the construction industry towards sustainable development.
