Dutch bridge construction using 3D printing technology
The 3D-built bridge is the first civilian project to adopt a new approach, with fast construction and low CO2 emissions.
The 3D-built bridge is the first civilian project to adopt a new approach, with fast construction and low CO2 emissions.
In the Netherlands, the country has more bicycles than people and uses this mode of transportation everywhere. Recently, they have adopted the latest construction technology when bridging the bike for 3D printing.
The bridge is not very special shape, made from bare concrete with dimensions 8 x 3.5m.
A Dutch researcher, Agence France Presse, has just unveiled a bridge at Gemert, the southeastern city. The bridge is not very special shape, made from bare concrete with dimensions 8 x 3.5m. The work was built by researchers from Eindhoven University of Technology, in collaboration with BAM Construction. The team said it was the first civilian work created by 3D printing technology.
The bridge across the canal connecting the two sides of the road, made of 800 layers of prestressed concrete. According to reports from Eindhoven, the notable new feature of the project is the technology that allows researchers to place reinforcement steel cables between concrete layers. Steel cable is used similarly to reinforced concrete in conventional concrete, which increases the hardness of the material.
Casting and demolition are eliminated, reinforced nets need not be placed separately.
The pre-printed 3D stereotype has a number of benefits with rapid construction speed. Casting and demolition are eliminated, reinforced nets need not be placed separately. The new technology also offers greater mobility, allowing for the creation of multiple concrete slabs.
Most importantly, 3D printing produces less carbon emissions than conventional methods. Cement produced from burning limestone at 1,400 degrees Celsius releases large amounts of CO2 that are harmful to the environment.
Thousands of vehicles are expected to roll over the bridge. In order to ensure that a large number of people are able to cross the bridge, Eindhoven and BAM say the bridge's test load can reach 5 tonnes. After the success of the project, the group is planning larger projects, including the construction of five homes using 3D technology.
