世界上最大的3D打印建築在迪拜完工

3D打印行業的翹楚埃皮斯公司最近宣稱他們完成了世界上最大的3D打印建築，該建築是一棟位於迪拜的兩層行政大樓，其基本結構僅使用了一台3D打印機進行打印。盡管如此，在該建築的建設過程中，人類建造者的參與也意義重大。

這座兩層行政大樓高9.5米，總建築麵積640平方米。其結構與其它3D打印建築類似，將水泥混合物通過噴嘴分層擠出來建立該行政大樓的基本結構。由於該建築比較大，而埃皮斯公司的3D打印機是便攜式的，於是打印機被固定在一個起重機上進行移動，一次打印建築物的一部分。隻有三個埃皮斯公司的工人在現場操作機器，整個項目大約花了三個星期完成。

雖然該建築物代表了3D打印建築又向前邁出了一步，但值得注意的是，該項目也涉及了大量的人類工作。除了鋪設地基，安裝窗戶、門、屋頂以及電線以外，建築工人還為該建築物增加了鋼筋和手工澆注混凝土的結構來增加其強度。

該公司的首席執行官兼創始人尼基塔·切尼翁泰表示：“建築的3D打印技術還處於早期發展階段。我們做了大量的研發工作，使這項技術能夠大規模應用。我們感謝有機會與杜拜合作，這個項目給了我們獨特的知識和寶貴的經驗，將幫助我們改善技術以及開發我們的3D打印機的新版本。改進後的版本將更可靠，效率更高。此外，在項目中，我們還測試並改進了我們自己開發的3D打印材料。該項目是建築3D打印行業向前邁出的一大步。”

埃皮斯公司之前3D打印了一個小房子，贏得了美國宇航局的太空棲息地挑戰。展望未來，該公司計劃明年在加利福尼亞州、路易斯安那州和佛羅裏達州建設社會福利住房項目。目前，該公司正忙於研究如何確保其3D打印的住宅符合建築規範。

3D printing specialist Apis Cor has completed what it calls the world's largest 3D-printed building. Located in Dubai, the basic structure of the administrative building was constructed using just one 3D printer, though involvement of human builders was significant.

The two-story administrative building measures 9.5 m (31 ft) in height and has a total floorspace of 640 sq m (roughly 6,900 sq ft).

Its construction was much like the other 3D-printed projects we've reported on and involved a cement mixture being extruded through a nozzle in layers to build up the basic structure of the administrative building. Because the building is so large, Apis Cor's 3D-printer, which is portable, was moved around on a crane, allowing it to build one section at a time. Just three of Apis Cor's workers were on-site to operate the machine and, according to Dwell, the entire project took three weeks.

Though the project, along with New Story's 3D-printed neighborhood, represents another step forward in 3D-printed architecture, it's important to note that there was significant human work involved. In addition to laying the foundations, adding the windows, doors and roof, plus wiring and the like, construction workers also added rebar and hand-poured concrete for structural support.

"Construction 3D printing technology is only at the early stages of development," says Nikita Cheniuntai, CEO and founder of the firm. "We do extensive R&D work to make the technology available for mass use. We are thankful for the opportunity to collaborate with Dubai Municipality. The project gave us unique knowledge and invaluable experience that will help us improve our technology and develop a new version of our 3D printer. The improved version will be more reliable and time efficient (twice as fast). Moreover, during the project we tested and improved our own-developed 3D mixture. This project is a huge step forward in the concrete 3D printing industry."

Apis Cor previously printed a 3D-printed tiny house and won NASA's space habitat challenge. Looking to the future, the firm plans to build affordable housing projects in California, Louisiana, and Florida next year. It's currently busy researching how to ensure its 3D-printed homes meet building codes.
