3D打印“抗霾樓” 樓高或達4 800米

Many of the worlds tallest skyscrapers will make you queasy if you reach their summit.

But these grand buildings could soon look like a bungalow in comparison to a three-mile high skyscraper envisioned by architects.

They say that the mighty tower could be built by 2062， using 3D printing technology to create walls that could withstand high winds and unique climates.

The skyscraper is the vision of Arconic， a materials science company based in New York， as part of its larger campaign called The Jetsons —— an homage to the 1962 cartoon， set in 2062.

Engineers from the firm are working with futurists to imagine how the world will look in 45 years.

The team has envisioned the Arconic tower —— a three-mile-high skyscraper created using materials that are either in-development or have already been brought to market.

As well as being staggeringly tall， the tower will also have futuristic features， including smog-eating surfaces， and retractable balconies.

Arconic is currently working on a project called EcoClean， a special coating that allows building to selfclean and purify the surrounding air.

Sherri McCleary， one of Arconics chief materials scientists， told Business Insider：‘The functional coating provides aesthetics， it provides maintenance benefits， and it also provides a benefit to the surrounding environment by reducing the content of pollutants around it.
