世界經(jīng)濟論壇:Future of Construction

世界經(jīng)濟論壇（The World Economic Forum）由于在瑞士小鎮(zhèn)達沃斯首次舉辦，所以也稱其為"達沃斯論壇"。

世界經(jīng)濟論壇(World Economic Forum)是以研究和探討世界經(jīng)濟領(lǐng)域存在的問題、促進國際經(jīng)濟合作與交流為宗旨的非官方國際性機構(gòu)?？偛吭O(shè)在瑞士日內(nèi)瓦。論壇"致力于改善全球狀況"宗旨，并影響全球未來經(jīng)濟發(fā)展的1000多家頂級公司。

12月6日，Boston  Consulting Group編寫論文《the Future of Construction Project》發(fā)表于世界經(jīng)濟論壇，盈創(chuàng)（Winsun）3D打印建筑作為重要案例列入其中，以下附原文：

A central platform to exchange best practices and ideas guiding the infrastructure and urban development industry in its transformation, and helping it to address its key challenges.

The construction industry has remained fundamentally unchanged throughout history: any vertical construction still requires workmen to add layers of building materials on top of each other. This approach is ill-suited to the modern age in three respects – it keeps productivity low, it is reliant heavily on the skills of individuals and it produces large amounts of waste, noise and dust.

Starting off as a building materials supplier, Yingchuang Building Technique (Shanghai) Co. Ltd, or Winsun as it is known,  aims to revolutionize this approach using 3D printing technology.Having developed the first continuous 3D printer for construction, the company printed the first batch of 10 houses in 2013 – making global headlines. Using a special ink made of cement, sand and fibre, together with a proprietary additive, the printer adds layer by layer to print walls and other components in its factory in Suzhou (China). The walls are then assembled on site. Winsun is also behind the first 3D printed office building opened in Dubai in May 2016.

“If you do not believe it is possible, we will print a prototype.”
Ma Yihe, President and Chief Executive Officer

Using up to 50% demolition waste or mine tailings for its ink and producing zero waste, the technology is very environmental friendly. More impressive even is the impact on delivery time: construction of a two-story 1,100 sqm mansion took one day of printing, two days of assembly, with internal bar structures erected in advance, requiring three workmen only. The company has developed several prototypes that clients can visit outside its main factory including a six-storey apartment building, an affordable house, a wave-shaped house or an ancient-style traditional Chinese house – taking full advantage of the technology’s freedom of design. But Winsun has advanced beyond prototyping and has sold more than 100 houses to date.

Being a pioneer of 3D printing technology in construction, Winsun faces several barriers to scaling up its solution – skepticism from designers, project developers and owners, and lack of regulation.
