This 40-foot-tall delta 3D printer can build homes out clay

Big Delta can build low-cost, 3D-printed homes in areas struck by natural disasters. 

It’s no question, 3D printers are getting bigger. While more and more companies are seeking massive build volumes, they will all pale in comparison to the latest design from WASP (World’s Advanced Saving Project). And we’re not talking about a large desktop machine, either. Standing at 40-feet tall, the Big Delta 3D Printer is capable of constructing entire houses — something that will be extremely useful in areas struck by natural disasters and throughout Third World countries.


Evident by advancements in recent months, 3D-printed buildings are bound to become ubiquitous over the next few years. And not only will the gargantuan delta-style printer be able to extrude habitable objects, it will be able to do so at very little cost by using local materials like clay.

Given its sheer magnitude, Big Delta is supported by a sturdy, 20-foot-wide metal frame. Although the printer will prove to be especially valuable in times of crisis, WASP says there’s already a growing interest in using it in places with a rapidly growing population. Considering that the United Nations estimates there will be a need for almost a hundred thousand new homes throughout the world each day for the next 15 years, the ability to quickly and inexpensively create homes will be paramount.


“Building Big Delta is much more than a dream come true,” its creators explain. “Estimates foresee a rapid growth of adequate housing requirements for over four billion people living with yearly income below $3,000.”

If you recall last year, the company unveiled a 20-foot-tall printer that could spew out filaments including mud and other natural fibers. Now, the team has taken their efforts one step further with the record-setting machine Big Delta. The printer uses a rotating nozzle that also doubles as a mixer, which enables it to keep the materials homogeneous for extrusion. These materials can then be treated and structurally reinforced with small amounts of chemical additives. What’s more, it reportedly only requires less than 100 watts of power to operate.


“[We] propose a vision that goes well beyond that of low-cost housing. We are talking about the Maker economy, a new model where everything can be self manufactured through shared solutions, These leverage on 3D printing and are tied to meeting life’s primary necessities: work, health and housing,” the team adds.

While few details about BigDelta have been made available, WASP will demonstrate the 40-foot-tall, 20-foot-wide beast of a printer at Maker Faire Rome. Interested? You can follow along on their website here.
