世界上最大的3D打印建筑在迪拜完工
3D打印行业的翘楚埃皮斯公司最近宣称他们完成了世界上最大的3D打印建筑，该建筑是一栋位于迪拜的两层行政大楼，其基本结构仅使用了一台3D打印机进行打印。尽管如此，在该建筑的建设过程中，人类建造者的参与也意义重大。
这座两层行政大楼高9.5米，总建筑面积640平方米。其结构与其它3D打印建筑类似，将水泥混合物通过喷嘴分层挤出来建立该行政大楼的基本结构。由于该建筑比较大，而埃皮斯公司的3D打印机是便携式的，于是打印机被固定在一个起重机上进行移动，一次打印建筑物的一部分。只有三个埃皮斯公司的工人在现场操作机器，整个项目大约花了三个星期完成。
虽然该建筑物代表了3D打印建筑又向前迈出了一步，但值得注意的是，该项目也涉及了大量的人类工作。除了铺设地基，安装窗户、门、屋顶以及电线以外，建筑工人还为该建筑物增加了钢筋和手工浇注混凝土的结构来增加其强度。
该公司的首席执行官兼创始人尼基塔·切尼翁泰表示：“建筑的3D打印技术还处于早期发展阶段。我们做了大量的研发工作，使这项技术能够大规模应用。我们感谢有机会与杜拜合作，这个项目给了我们独特的知识和宝贵的经验，将帮助我们改善技术以及开发我们的3D打印机的新版本。改进后的版本将更可靠，效率更高。此外，在项目中，我们还测试并改进了我们自己开发的3D打印材料。该项目是建筑3D打印行业向前迈出的一大步。”
埃皮斯公司之前3D打印了一个小房子，赢得了美国宇航局的太空栖息地挑战。展望未来，该公司计划明年在加利福尼亚州、路易斯安那州和佛罗里达州建设社会福利住房项目。目前，该公司正忙于研究如何确保其3D打印的住宅符合建筑规范。

World's largest 3D-printed building completed in Dubai
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.
