Cazza has launched a line of automated construction machines capable of 3D-printing entire buildings.

The robots are capable of constructing entire houses, villas, office buildings, and other structures. The Cazza X1 mobile tracked model is able to build structures of up to three storeys in height.

The US-headquartered construction automation firm claims that its machines are faster, cheaper, and more sustainable than conventional methods.

The Cazza robots use an in-house blend of concrete, formulated for additive manufacturing, to transform digital models into physical structures. The machines use less than half the concrete typically required to build equivalent structures, according to the company.

A statement released by the company said: “This announcement by Cazza is a landmark in the race to bring commercial 3D-printing construction systems to market. As of today, Cazza is the only company with a commercial construction robot of this nature on offer to the public.”

Cazza was founded in Silicon Valley by Chris Kelsey and Fernando de Los Rios. The company has already tested its 3D-printing technologies in Dubai’s high ambient temperatures.

While Cazza is not limiting orders, production quantities are restricted. Only 30 machines of each type will be available during the first round of production.

The robotic builders are now available for purchase globally via the company’s website.
