3D Printer can make entire houses from Clay

Is this the Answer for Housing Shortages in Low wage Nations?

3D printers are the next big thing for home use and we all know about the industrial uses that have come to the forefront in recent years. 3D printers have the ability to produce one off components that may not be available, all the way up to complete electrical, mechanical and electronic devices. What about complete low cost housing? Check out the video to find out how this will work and feel free to leave a comment.

An Italian collective called the World’s Advanced Saving Project (WASP) has unveiled what it says is the world’s largest 3D printer, BigDelta, which can create budget-friendly mud huts in one continuous printing session.

Inspired by traditional clay house architecture and construction methods, the 12-metre high machine was unveiled by its makers this week, who say their 3D printer may provide a solution to housing shortages for the world’s poor.

Citing United Nations figures, which estimate that 4 billion people with annual incomes of under US$3,000 will require low-cost housing by 2030, WASP argues that devices like BigDelta will be required in place of more costly and pollution-heavy building methods.

BigDelta can make houses out of mud, clay, water, dirt, and natural fibres, avoiding the expense and environmental consequences of cement. Best of all, clay houses don’t require much in the way of maintenance once they’re up, and can last for years with thin applications of new clay over their external surfaces every five years or so

The machine operates much like a conventional filament-based 3D printer, except everything of course is at a much larger scale. While the gargantuan frame looks imposing, WASP says it’s lightweight and easy to assemble and transport. The frame serves to support a giant printing nozzle that slowly extrudes what becomes the walls and ceilings of entire houses in a circular motion, layer upon layer, from the ground up.

The distinctive house shapes it can create (seen here at lower scale) are said to be informed by a breed of wasp that constructs mud homes, and also draw inspiration from traditional hut dwellings.


Let’s hope that this technology is adopted by developers to improve the housing standards of the emerging worlds population. Time will tell…
