There are not many ways to build a house apart from the way houses were always built, that is, by erecting four walls and then adding a roof. However, this age-old technology eventually had to be modernized, and as with everything else in our lives today, technology does that modernization. In that case, instead of being built the old-fashioned way, houses can now be printed.
Last week at the South By Southwest Festival in Austin, Texas, ICON and ICON, the non-profit organization for residential construction technologies, have their version of a 3D printed house. The model is 650 square meters and consists of a living room, kitchen, bedroom, bathroom and shady veranda. It finished in less than 24 hours from scratch and cost less than $ 1
This is not the first 3D printed house to pop up (or rather plop); There are similar structures created with similar technology in Russia, Dubai, Amsterdam and elsewhere, but this is the first 3D printed house to rise in the US.
ICON's crane-like printer is called Vulcan and pours a concrete mix into a software-dictated pattern; instead of one wall going up at a time, only one layer is laid, the whole structure "grows" from the ground up. The printer consists of an axis arranged on a web, giving it a flexible and theoretically unlimited printing surface.
"With 3D printing, you not only have a continuous thermal envelope, high thermal mass, and near-zero waste, but you also have speed, a much wider range Design palette, next-level elasticity and the possibility of a quantum leap in affordability, "said Jason Ballard, ICON co-founder. "That's not 10 percent better, it's 10 times better."
The house has a bigger purpose than just techies. The vision of ICON and New Story is that 3D-printed homes serve as a safe, affordable housing alternative for those in need. New Story has already built more than 800 homes in Haiti, El Salvador, Bolivia and Mexico, working with communities that employ local workers and buy local materials instead of shipping everything from abroad.
New Story is raising $ 600,000 to fund a planned 100-family home in El Salvador. It will be the first community of 3D printed houses. The pressure will begin later this year, and the goal is for families to move in by Q3 2019. Donors can finance a full house with only $ 4,000.
Six hundred and fifty square feet may not sound like much space for more than one or two people, but it's a big step up from the meager homes and shacks that make up the slums where millions of people live. ICON and New Story hope that the Salvadoran community will serve as a scalable model that can be exported to developing countries around the world, providing a high-quality housing option for millions of people who currently lack one.
"Instead of waiting for profit motivation to bring design advances to the global South, we are f-tracking innovations such as home 3D printing, which can be a powerful tool to end homelessness, "said Alexandria Lafci, COO of New Story.
Homes Built to Last International Standards (19659002) Although 3D-printed houses are a great alternative to the flimsy caravans that millions of people call homes, there are some limitations they can consider to find a solution to global housing shortages. 19659002] The greatest need for affordable, secure housing in developing countries exists in or near major cities; Take, for example, the slums of Cape Town, Nairobi or Mumbai. Replacing the current homes of families at these locations with printed houses could prove difficult, simply because of space constraints. 3D printed communities are much more practical in rural areas where population density is lower, and may not be a truly scalable solution in urban areas until communities become vertical. 3D-printed skyscrapers are already under construction, but not yet for affordable housing.
When skyscrapers can be printed and used as offices, it is only a matter of time before they can be used for housing. And in the meantime, $ 4,000 per pop is a solid step in the right direction for a safe, comfortable home that did not have a home before.
