3D printing could soar to new heights with the construction of the first 3D-printed skyscraper in the world. Dubai-based firm Cazza recently announced they aim to print the high-rise in the United Arab Emirates. They will draw on a novel construction technique known as crane printing.
To print their ambitious skyscraper, Cazza will draw on cranes with added units designed for constructing 3D-printed buildings higher than 262 feet. It’s not yet known how tall the skyscraper will be. The company’s CEO Chris Kelsey said when they started their company, they focused on 3D-printing low-rise structures or houses, but developers kept asking about skyscrapers, so they decided to adapt their technology to reach higher.
The crane printing process includes all the major structural components needed by towering buildings, according to Construction Week Online. Current construction methods will complete the rest of the building. Mechanical engineer Xavier Hernand said there are vast possibilities for what kind of materials they could use, including steel or concrete.
Cazza Chief Operating Officer Fernando De Los Rios said, “The crane printing system can be easily adopted with existing cranes which means we don’t have to build cranes from scratch. We are adding new features to make it adaptable to high wind speeds along with the use of our layer smoothing system that creates completely flat surfaces. You won’t know it’s 3D printed.”
Cazza gained notice for blending mobile 3D printing robots with existing building methods to speed up construction processes and make them more cost effective and environmentally friendly.
Kelsey said, “Through our technologies, we will be able to build architecturally complex buildings at never-before-seen speeds. It is all about economies of scale where the initial high technology costs will reduce as we enter the mass production phase.” The company has not yet announced a start date for the skyscraper construction.
