In the construction industry, additive manufacturing is being widely used today. Whether it\u2019s to build\u00a0houses<\/a>,\u00a0schools<\/a>, or even bridges, 3D technology offers great benefits. In terms of structures and walkways of urban architecture, 3D-printed bridge projects have multiplied in recent years. Many countries are now using\u00a0additive manufacturing<\/a>\u00a0to build these connecting structures, in part due to the low cost. To learn more about these sorts of projects and how additive manufacturing facilitates the construction of bridges, we have compiled a list of some of the most preeminent initiatives of recent years,\u00a0whether they are completed or currently still under construction.<\/p>\n

A Walkway Made With 60% Less Material<\/h2>\n

Although it seems difficult to believe, this project is a reality. Specifically, it was Ghent University that carried out the initiative to create a walkway through additive manufacturing that required less material and had a reduced environmental impact. On the project, Ghent University worked with Vertico and Technion – Israel Institute of Technology to design the pedestrian bridge, which is not very impressive for its size, but it is impressive in terms of aesthetics, and especially striking for being a bridge with optimized topology. For this, they used their concrete 3D printer<\/a> that offers a printing volume of 4.5 x 2 x 2.5 m, with a material specially designed for this purpose. In this way, the company aims to reduce CO2 emissions<\/a> and increase productivity in the construction sector.<\/p>\n

\u00a0The Technological University of Eindhoven’s Collaboration<\/strong><\/h2>\n

Acclaimed architect Michiel van der Kley, along with Summum Engineering and Witteveen+Bos collaborated with the Technological University of Eindhoven (TU\/e) on the design of the 3D model for the longest 3D-printed bridges built for cyclists. The bridge was manufactured in the 3D printing center of Saint-Gobain Weber Beamix, which uses several BAM robotic arms. The 29-meter-long bridge was designed with round and natural shapes to blend in with its outdoor placement.<\/span><\/p>

Acciona 3D-Prints a Bridge in Madrid<\/h2>\n

We could say that these were the first 3D-printed bridges installed in the world. Located in Alcobendas, in Madrid, the concrete structure was created by the Spanish company Acciona, which works with several business lines, including energy, infrastructure, and for a few years, additive manufacturing. Although Acciona was in charge of the 3D printing process, the concrete pedestrian bridge was designed by the Institute of Advanced Architecture of Catalonia. Regarding the more technical aspects, we can highlight that the bridge is 12 meters long and 1.75 meters wide, which represents a milestone in civil engineering in the Iberian country. In addition, its design has an organic and biomimetic architecture, resembling forms of nature.<\/p>\n

The First 3D-Printed Bridge in the Netherlands<\/h2>\n

In 2017, the Eindhoven University of Technology (TUE) and the company BAM Infra designed the first 3D printed concrete bridge in the Netherlands. Made up of 800 layers of concrete, the 8-meter long and 3.5-meter wide bridge is located over a ditch and thus connects two roads. As in many situations, TUE and BAM Infra claim to have minimized, through 3D printing, the amount of concrete needed to build such a structure. Located in the town of Gemert, the bridge was built in just 3 months.<\/p>\n

Shanghai’s Longest Concrete Bridge<\/h2>\n

An impressive 176 units of cement support the longest 3D-printed concrete bridge in China (originally the World before being overtaken by a project in the Netherlands), allowing pedestrians to cross the Shanghai Canal. The bridge was designed by a team led by Professor Wu Weiguo from Tsinghua University and made using additive manufacturing next to Wisdome Bay. Inspired by the historic Anji Bridge in Zhaozhou (China), the pedestrian structure in Shanghai is intended to be representative of the potential of 3D technology for engineering projects of all kinds. Two robotic arms were used for the construction, creating the concrete arch in 450 hours. The team claims that it was possible to save two-thirds of the implementation costs compared to conventional manufacturing processes.<\/p>\n

A 3D-Printed Retractable Bridge<\/h2>\n

Last summer, China unveiled another bridge designed in part thanks to additive manufacturing, this time with a very special feature. It was designed to retract at any time and is controlled by a simple button connected via Bluetooth. The entire bridge has not been 3D printed, it is simply made up of triangular panels custom made by additive manufacturing in just 3 days. These 36 elements were made with a composite material from recycled materials. The bridge is 9 meters long and 1.5 meters wide and was installed in Wisdom Bay Park.<\/p>\n

Marine Corps Combat Testing 3D-Printed Bridges<\/b><\/h2>\n

In 2019, the United States Marine Corps had a training program for special divisions on the field operation of an Automated Construction of Expeditionary Structures (ACES) printer. While the Marine Corps is still experimenting with the use of large concrete and aluminum printer systems, they plan to be able to deploy these types of 3D printers that will allow field engineers to create custom-made bridge structures for crossing any land gap. \u201c<\/span>The only restraints right now are working out intellectual property deals with industr<\/span><\/i>y.\u201d, explained Captain Matthew Friedell, the team leader of the Advanced Manufacturing Operations Cell in the Marine Corps Rapid Sustainment Office. Within the next few years or so, he predicts the additive manufacturing industry and the U.S. Department of Defense will have worked out deals for using proprietary 3D technology.<\/span><\/p>\n

A Pedestrian 3D-Printed Bridge in Rotterdam<\/h2>\n

A collaboration between Royal HaskoningDVC, CEAD and Covestro has resulted in the first lightweight 3D printed pedestrian bridge prototype, which was made using a glass-filled thermoplastic composite material. The companies claim that they chose the material as fiber-reinforced polymer bridges are known for having a longer lifetime expectancy and lower life cycle costs compared to steel. They also note that apparently this is the first time that someone has used 3D printing technology to make a bridge made out of large-scale continuous fiber reinforced thermoplastic parts. For the technology, they used fused granulate fabrication and Arnite AM8527 pellet material from Covestro. They name a number of benefits to the bridge including having a reduce construction time, increased sustainability, reduced maintenance burden and increased lifespan. Currently, the bridge only exists as a prototype, however ultimately it will be installed in Kralingse Bos park in Rotterdam.<\/p>\n
