How does the house printed by 3D-technology look like? Is the quality guaranteed? On Jan. 18, at Yingchuang New Material (Suzhou) Company, Suzhou branch of Yingchuang Construction Technology (Shanghai) Company, a 3D-printed villa and a 5-storey building made their full debut, which attracted extensive attention from many experts, investment banks and domestic and foreign media.

3D-printed walls are integral without cracks

The walls seem like 2cm concrete. They feel rough, but look integral with no cracks even in the corners. However, seen from the part between the floors and walls, it should be pieced together. “The 3D-printed buildings are printed in the factory, and then they are cut and transported here. The floors are cast in place. If the whole building is printed, it will be unable to transport.” General manager of Yingchuang New Material (Suzhou) Company Zheng Jian said.

President of Yingchuang Construction Technology Company, Ma Yihe said, for them, there is no technical problem to print a whole building, as long as the construction printers are moved to the site. Now, they are still upgrading technology and they will realize printing whole buildings in three years. What does the construction “ink” made from? “raw materials are mainly construction wastes, industrial wastes and mine tailings, others are concrete and reinforcement as well as special auxiliaries.” Apart from the “ink”, they also develop GRG, SRC, FRP, etc.

Construction cost can be saved by 50%. Egypt has ordered 20000 3D-printed houses.

The global briefing of Yingchuang 3D-printed green buildings attracted 300 construction experts, investment bankers and reporters. Ma Yihe said that, the biggest advantage of 3D-printed buildings is saving materials because it produces no dust and wastes. It is really good news for citizens suffering from smog. What’s more, it turns wastes into wealth, and saves construction cost by over 50% with lower cost and in shorter period.
