The luxury 3D printed estate set to be made from sand, dust and gravel
Now, a 3D printed estate featuring a swimming pool, jacuzzi, car port and 2,400 square foot house could be coming to a sleepy plot of land in upstate New York.
The ambitious project is being undertaken by New York City architect Adam Kushner, alongside partners including 3D-printing pioneer Enrico Dini and his D-Shape firm.
Kushner told CNN that surveying has already begun with excavation work also set to commence soon.
The swimming pool and jacuzzi are penciled in to be completed by December 2015 while construction of the house is expected to continue until the end of 2017, he says.
But the project hinges on getting the giant 3D printer, which will be used to produce the digitally designed building blocks of the estate on-site, into the country.
The device is currently in Italy after it was originally being built for a project partly funded by the Italian defense agencies. Military clearance is now required before the green light is given to export the printer to the United States, Dini says.
The delay in receiving this clearance is part of the reason the project has been held up since it was first announced back in August 2014.
“We are now waiting (for) permission to borrow the printer (from the military),” Dini says. “If I had another printer I’d send it there tomorrow, but unfortunately we don’t have and must wait.”
The litmus test
Whatever the import-export issues, Kushner says he sees the estate project as a test of D-Shape’s printer technology and its distinctive method.
This practice entails collecting sand, dust and gravel on site and mixing them with a magnesium-based binding agent to produce the 3D-printed building blocks required to piece the estate together. According to literature on the D-Shape website, the material produced by the printer is “similar to marble” in its constitution.
This technique is vastly different from other 3D-printing methods, Kushner says, and enables the production of many more “sculptural forms” that simply aren’t possible with other systems.
If D-Shape can prove its technology works and is efficient for a project of this size, Kushner believes it could lead to all manner of possibilities in architecture and construction. Not only could it be faster and safer than existing construction methods, he says, it could also end up being cheaper, more streamlined and of higher quality.
And although the 3D-printed estate is something only the very wealthiest would be able to replicate, Kushner sees D-Shape’s construction methods benefiting the less fortunate as well.
“This will serve as a way of using our project to … pave the way for more humanitarian purposes that we see as the highest and best use for our technology,” he says.
“If we can build a simple pool house, I can print thousands of refugee housings. If I can build a pool, I can print underwater reefs (which he says D-Shape has already done before) to repair bridges, piers and infrastructures.”
A technology on the rise?
Integrating progressively more advanced 3D-printing methods into the construction industry has been a topic that has generated many eye-catching headlines in recent years.
The process of contour crafting — where large 3D printers are assembled on a building site (much like what will happen on Kushner’s estate) and programmed to construct pre-designed concrete structures and their relevant sub-components — was put forward by Dr. Behrokh Khoshnevis of the University of Southern California as far back as 2009.
Khoshnevis told industry website 3DPrint.com earlier this year that the first printers large enough for his version of contour crafting should become available within the next two years. He added that the method could even be used to build high-rise structures within ten years.
Chinese firm WinSun seemed to take inspiration from Khoshnevis’ methods when they claimed to have 3D printed a mansion and six-story tower block in the city of Suzhou, eastern China earlier this year.
Meanwhile, in the Netherlands, DUS Architects continue to piece together a 3D-printed house using its “KamerMaker” machine. Company co-founder Katherine De Wit described the DUS technique as being a potentially valuable tool that could be added to those already used to build homes.
Other experts, however are more cautious about the immediate potential of 3D-printing technology in the construction industry.
In an interview with CNN in 2014, Dr. Phil Reeves, managing director of UK-based 3D-printing consultancy and research firm Econolyst, described 3D-printing a house on site like that planned by DUS as counter to existing building techniques which are already relatively efficient.
Then there are other fast-developing building methods like prefabricated construction which entails manufacturing components in a factory before transporting and rapidly piecing them together on a building site.
Chinese firm Broad Sustainable Building claimed to have used this method to piece together a 57-story skyscraper in just 19 days earlier this year.
For Kushner, however, the benefits of large-scale 3D-printing are many and will likely increase as the technology becomes more advanced.
“This is not superfluous, nor a lazy architects idyll,” he says. “I think it’s as important as the automobile was in changing the design of cities or how the printing press altered communication.”
“Why? Because it democratizes construction and architecture and puts it into everyone’s hands, just like the camera phone made everyone a photographer. Not everyone is good at it but everyone can become one.”
