The first ten 3D printed houses have been put into use at Qingpu District, Shanghai. The size varies from 24 to 60 square meters on one floor; a single unit has been constructed in two floors.
The walls of these structures are concrete which have the function of insulation, but air-con is necessary in summer.
The core technology of 3D printed house lies in the printing material which is mainly made from construction waste, according to Yingchuang Company, the research and development manufacture of these houses.
Compared to tradition construction, the building period of 3D printed house is shorter; the cost is 30% to 50% less. And the life span of these houses can be thirty to fifty years.
The company is going to build a 3D printed architecture industrial park and an urban construction waste disposal centre at Qingpu District.
