A crew of researchers and trade companions have unveiled a brand new 3D printed bridge design now on show on the European Cultural Centre’s Time House Existence exhibition in Venice, working from 10 Could to 23 November 2025.
Led by Professor Dr. Masoud Akbarzadeh, Founding father of the design apply Huge Kind, and Director of the Polyhedral Buildings Laboratory on the College of Pennsylvania, in partnership with Swiss firm Sika Group, the undertaking investigates how computational geometry and robotic 3D printing will be utilized to concrete development in ways in which enhance effectivity, adaptability, and sustainability.
Often known as Diamanti, the construction is fashioned from 9 prefabricated concrete segments, every produced with a two-component cementitious combine developed by Sika and printed utilizing a robotic arm. The geometry of every section contains hole sections and patterned surfaces that keep structural integrity whereas decreasing embodied carbon.
The segments are assembled utilizing eight ungrouted metal cables in a post-tensioned system, a technique that avoids adhesives and grout, making all the bridge totally demountable and recyclable.
The novel Diamanti bridge
For this undertaking, two variations of the Diamanti bridge have been constructed to this point. The primary, a 2.5 m prototype produced by Dutch firm Vertico, is the piece on view in Venice. In-built France by Carsey3D, the second extends to 10 m and has undergone testing at a 9 m span, confirming that the system will be scaled for sensible use.
Its structural logic is formed by Polyhedral Graphic Statics (PGS), a technique that maps the move of compressive and tensile forces by a polyhedral framework. This strategy leads to segments with diamond-shaped anticlastic surfaces, which give stiffness, distribute masses extra successfully, and minimize concrete use with out sacrificing energy.
Though the show mannequin has a depth of simply 26 cm, the identical ideas will be utilized to for much longer spans. The modular format is meant to restrict waste throughout manufacturing, ease transportation of elements, and make dismantling easy when the bridge reaches the top of its service life.
In response to designboom, work on the bridge introduced collectively experience from a number of fields. Put up-tensioning techniques engineering agency AEVIA provided the post-tensioning system, researchers at Metropolis Faculty of New York (CCNY) and Villanova College carried out unbiased structural evaluation, and the Centre d’Etudes et de Recherches de l’Industrie du Béton (CERIB) institute in France performed load testing.
Collectively, these contributions have turned Diamanti right into a working prototype for low-carbon, demountable infrastructure, linking computational design with new supplies and additive manufacturing.
3D printed bridges increase worldwide
Additive manufacturing is being adopted worldwide in bridge constructing, viaducts, and different civil engineering tasks for its capability to enhance materials effectivity whereas lowering prices and development time.
In keeping with this, a 15.25 m 3D printed pedestrian bridge was unveiled in China by a partnership between Shanghai Mechanized Development Group Co. and filament producer Polymaker. Designed to exhibit pollution-free constructing strategies and the mixing of “good” applied sciences, the undertaking mirrored how additive manufacturing was being utilized to public infrastructure.
Within the Netherlands, world dietary science and supplies firm DSM took half in constructing a 3D printed footbridge in Rotterdam’s Kralingse Bos park utilizing recyclable supply supplies. The set up was notable for being the primary to include fiber-reinforced thermoplastics, increasing the scope of supplies utilized in bridge development.
Paris additionally noticed advances in large-scale printed infrastructure. A consortium that includes 3D printing agency XtreeE secured a contract to design and construct a 40 m 3D printed pedestrian bridge from structural concrete in preparation for the 2024 Olympic Video games, signaling rising acceptance of the expertise in high-profile city tasks.
