Can you 3D print whole cities? The folks at Cazza think they can

Chris Kelsey is a high school dropout. He’s also a millionaire and a serial entrepreneur.

"Growing up as a teenager, I didn’t have any money," he tells Tech in Asia. "And when I started Appsitude, I finally did, and I was thinking, what is something that we can do to change the world?"

Chris is the co-founder and CEO of Cazza, a construction automation company. Before that, he was the CEO of Appsitude, a mobile app development and marketing start-up.

In October, Appsitude was acquired by Indian entrepreneur and investor Deepansh Jain, giving Chris the chance to turn his attention to something with more social impact, like building environmentally sustainable, low-cost housing. That’s what he and his co-founder, Fernando De Los Rios, hope to achieve with Cazza.

Cazza wants to automate as much of the construction process as possible, from laying down foundation to building walls. The company has developed its own proprietary construction material: a concrete-like substance that it says is up to 80 per cent recycled material.

Another one of Cazza’s products, a portable, crane-like 3D printer, can extrude this material into walls, layer by layer. Through the company’s software, users can design their own 3D models, or draw lines where they want material printed and at what height. According to Cazza, the company’s 3D printing machine can build a 100 square metre house within 24 hours.

Unlike other 3D printing construction companies, such as Winsun, which built a 3D printed mansion in China last February, there’s no assembly required. Instead of printing pieces of the house in warehouses and trucking them to the construction site, Cazza says it can build directly on site.
