ACCIONA builds 3D-printed concrete bus stop for Ajman Transport Authority
ACCIONA has constructed a bus stop using 3D concrete printing technology for the Transport Authority of the Government of Ajman.
The bus stop, which weighs almost 3 tons and is 4.5m long, 2m wide and 2.3m high, consists of 3 printed pieces. It took less than 10 hours to be printed.
Luis Clemente, ACCIONA 3D Concrete Printing Business COO, highlighted the relevance of this initiative: "We are glad that the Transport Authority of the Government of Ajman has chosen us to carry out this project, as it serves as a demonstration of their commitment to innovation. This project allows us to showcase another way of applying 3D concrete printing technology: making iconic, innovative and sustainable urban street fittings. It is also the first to be carried out using this Powder Bed technology in the Middle East".
The benefits of manufacturing this type of urban furniture with our 3D concrete printing technology, as opposed to the conventional construction methods, are the reduction of waste (no molds or forms are used whatsoever), the lessening of CO2 emissions and the possibility of having total freedom over the structural design. In this specific case, the bus stop’s design allows for the placement of solar panels on the roof.
Jesús Sancho, managing director, ACCIONA Middle East, said: "We are delighted and proud to see that the leaders and visionaries of the Government of Ajman share the same passion for innovation, cutting-edge technology and while sharing the same interest in deploying sustainable solutions as ACCIONA does. We deeply appreciate the trust placed by the top management of the Transport Authority of the Government of Ajman since the first time that they visited our facilities and believed in this project.”
ACCIONA owns and operates the largest fully functional concrete 3D printer in the world with the powder bed technology, which is a particularly suitable option for generating pieces with complex shapes that require structural resistance. It works with concrete as the raw material, making it an ideal solution for the use in architecture, urban planning and building.
The 6mx3mx2m printer allows greater efficiency and automation of construction processes, making possible a freedom of architectural and urban design unknown until now, and the production of exact replicas of any sculpture to enhance cultural and historical heritage.
ACCIONA chose Ras Al Khor Industrial Area to install its 3D printing hub to support the 'Dubai 3D Printing Strategy' and their commitment to deploy this 3D technology in all areas of the economy, specifically, in the construction sector.
