A construction firm based in Dubai has announced plans to build the world's first 3D-printed skyscraper.
The company, called Cazza, has confirmed that it will be erected in the United Arab Emirates. It says it will use a new technique called “crane printing“ to create the building. “When we first thought of implementing 3D printing technologies, we were mostly thinking of houses and low-rise buildings,“ Cazza CEO Chris Kelsey told Construction Week Online. “Developers kept asking us if it was possible to build a 3D printed skyscraper. This led us to begin researching how we could adapt the technologies for taller structures.“
Buildings have been 3D-printed before, with the key benefits being low costs and speedy completion. “Through our technologies, we will be able to build architecturally complex buildings at never-before-seen speeds,“ added Kelsey. “It is all about economies of scale where the initial high technology costs will reduce as we enter the mass-production phase.“ Cazza is yet to disclose the building's planned height or any commencement or completion dates, but the Encyclopedia Britannica describes a skyscraper as a building “of unusual height, generally greater than 40 or 50 stories“.
Concrete and steel will be two of the materials printed by the company's cranes.
Plans for the world's first rotating skyscraper, meanwhile, were detailed in February. Set to be built in Dubai by 2020, it will stand at 1,375 feet tall, with each of its 80 storeys capable of rotating individually around a concrete core.
