Leading Saudi real estate developer Dar Al Arkan has announced the successful completion of the world’s tallest 3D printed building - a three-storey smart home villa - in capital Riyadh. 
The 9.9-m-tall building was 3D printed in just 26 days using a 3D construction printer from Denmark-based Cobod International.
The villa, the first 3D printed building from Dar Al Arkan, is fully compliant with the building codes, making it a bright example of how technology and innovation can work hand in hand with safety and regulation, said the srtatement from the Saudi developer. The villa features several smart home features and the use of new materials.
Low-cost local materials were used to create the 3D printable concrete, with which all the walls of the 330 sq m building were printed with.
The building was made without the use of a tent just after the summer in a hot desert where temperatures run as high as more than 40 degrees, it added.
Wael Al Hagan, the 3D construction printing project manager from Dar Al Arkan, said: "Our efforts are focused on developing the kingdom’s real estate sector by integrating the latest trends and technologies, drawn from global best practices to enhance our industry locally and deliver on the objectives of vision 2030."
"The introduction of 3D construction printing enables us to focus on greater flexibility of design, strengthen productivity and achieve higher cost efficiency," he noted.
According to him, the villa features smart applications that control various functions of the house, including doors, locks, AC, lighting and has 9 solar panels on the roof, which generate enough electricity to power many of the villa's systems, including lighting and heating. 
Also, heat-reflecting nano-technology was used for painting the exterior walls, which makes the villa up to 40% more heat-resistant than traditional buildings. In addition, the exterior of the house is four times stronger that any regular-built one, he stated.
"The level of design flexibility, made possible using cutting-edge 3D printing technology, allows for easy and quick customization of finishes and styles, enabling Dar Al Arkan to offer its future clients a truly personalized experience," explained Al Hagan. 
"With this feature, the company aims to create homes that are tailored to the unique tastes and preferences of their clients, setting a new standard in the real estate industry," he added.
On the use of new technology, Fahad Al Nasar, the Head of Innovation, The Ministry of Housing in Saudi Arabia, said: "We are rapidly developing in the construction sector through our building technology initiative and implementing new measures to enable 70% of the Saudi population to have their own homes by 2030. Our strategy is to revolutionize the way people think about home through smart futuristic methods."
Dar Al Arkan said the project was executed using local materials and the D.fab solution developed by Cemex and Cobod. 
This solution allows its customers to use 99% local and inexpensive materials, while only relying on 1% sourced from a central location.
On the completed 3D printed villa, Henrik Lund-Nielsen, the Founder and General Manager of Cobod, said: "The three-storey villa from Dar Al Arakan is really representing state of art of the 3D construction printing industry both in terms of size and quality and in many other ways. The villa demonstrates the capabilities of the technology regarding scale, speed, use of cheap local materials and innovative solutions."
"Our technology delivers the fastest construction method in the world, and when this is combined with low-cost locally made concrete a winning formula has been established," he added.-TradeArabia News Service
