世界经济论坛:Future of Construction

世界经济论坛（The World Economic Forum）由于在瑞士小镇达沃斯首次举办，所以也称其为"达沃斯论坛"。

世界经济论坛(World Economic Forum)是以研究和探讨世界经济领域存在的问题、促进国际经济合作与交流为宗旨的非官方国际性机构。总部设在瑞士日内瓦。论坛"致力于改善全球状况"宗旨，并影响全球未来经济发展的1000多家顶级公司。

12月6日，Boston  Consulting Group编写论文《the Future of Construction Project》发表于世界经济论坛，盈创（Winsun）3D打印建筑作为重要案例列入其中，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.
