Dubai has taken a step further along the road to making such dreams a reality by announcing that 25% of the city-state’s new buildings will be made using 3D printers by 2025.

The move is part of an ambitious 3D-printing strategy announced in 2016 by Sheikh Mohammed bin Rashid Al Maktoum, vice-president and prime minister of the United Arab Emirates and the ruler of Dubai.

The 3D-printing strategy aims to reduce labour by 70% and cut costs by 90% across different sectors, according to the Dubai Future Foundation.

Perhaps more crucially, 3D-printing construction has the potential to help solve a looming homelessness crisis as more people gravitate to living in cities: the UN predicts that by 2030, the world will have 41 mega-cities with more than 10 million inhabitants.
