A team of researchers and industry partners has presented a new 3D -printed bridge design, which is now being exhibited at the period of existence at the European Cultural Center in Venice and runs from May 10th to November 23, 2025.
Under the direction of Professor Dr. Masoud Akbarzadeh, founder of the Massive Form and Director of the Laborial Polyedral Structures at the University of Pennsylvania, examines the project, which in cooperation with the Swiss company Sika Group is examined how computational geometry and robot -3D printing can be applied to concrete construction work, the efficiency, adaptability and adjustability, adaptability and adaptability Adjustability, adaptability, adaptability, adaptability, adaptability, which can improve adaptability.
Known as Diamanti, the structure is formed from nine prefabricated concrete segments, each developed with a two -component mix -capable mix developed by Sika and printed by a robot arm. The geometry of each segment includes hollow cuts and structured surfaces that maintain structural integrity and at the same time reduce embodied carbon.
The segments are compiled in a recessed system with eight non -cast steel cables, a method that avoids adhesives and grouts, which means that the entire bridge is completely destroyed and recyclable.
The new Diamanti bridge
So far, two versions of the Diamanti bridge have been built for this project. The first, a 2.5m prototype from Dutch Company Vertico, is the piece in Venice. The second, built in France in France, extends to 10 m and was examined with a span of 9 m. This confirms that the system can be scaled for practical use.
Its structural logic is shaped by polyedric graphics statics (PGS), a method that depicts the flow of pressure and tensile forces through a polyedical scaffolding. This approach leads to segments with diamond -shaped anti -clastic surfaces that deliver stiffness, distribute loads more effectively and reduce the concrete use without sacrificial strength.
Although the display model has a depth of only 26 cm, the same principles can be applied to much longer spans. The modular format is intended to restrict waste during production, facilitate the transport of components and make disassembly uncomplicated when the bridge reaches the end of its lifespan.
According to the design boom, the work of the bridge has brought together specialist knowledge from several areas. The engineering company, Aevia, provided the post-voltage system, researcher at the City College of New York (CCNY) and Villanova University independent structural analyzes and the Center D'Etudes et de Radumerches de l'Inustrie du Béton (cerib) institutions carried out in France.
Together, these contributions have transformed Diamanti into a functioning prototype for low -carbon, grueling infrastructure, whereby the computing design is linked to new materials and additive production.
3D printed bridges expand worldwide
Additive production is used worldwide in bridge construction, viaducts and other civil engineering projects for the ability to improve material efficiency and at the same time shorten the costs and construction time.
In this context, a 15.25 m 3D -printed pedestrian bridge was unveiled in China by a partnership between the mechanized design group of the Shanghai and the filament manufacturer. The project was developed to demonstrate environmentally free building methods and the integration of “intelligent” technologies and reflected on how additive manufacturing was applied to public infrastructure.
In the Netherlands, the Global Nutritional Science and Materials Company DSM took part in the construction of a 3D printed pedestrian bridge in Rotterdams Kralingse Bos Park with recyclable source materials. The installation was remarkable that it included thermoplasty as the first fiber -reinforced thermoplasty and expanded the material size used in bridge construction.
Paris also saw progress in the large -scale printed infrastructure. A consortium with 3D printing XTreee secured a contract to design and build a 40 m 3d printed pedestrian bridge from Structural concrete to prepare for the 2024 Olympic Games, which signals growing acceptance of technology in top-class urban projects.
