On 29th March 2014, Chinese engineering giants WinSun printed ten 3D houses, each measuring 200sqm at a cost of around €4,250 each. Constructed entirely in concrete using a colossal 3D-printer, the project was the first of its kind and widely acknowledged as an indication of things to come.
Now, almost a year later, WinSun have announced the completion of the world’s tallest 3D-printed structure, a 5-storey residential building together with the first ever 3D-printed villa measuring 1,100sqm.
WinSun has been established for more than a decade; currently holding 98 national patents for construction materials, they are innovators in 3-dimensional printing technology. Their success is attributed to the company’s unique techniques, having developed an exclusive 3D printing ‘ink’ which is a mixture of recycled construction waste, glass fibre, steel, cement and special additives.
Winsun’s 3D-printed 5-bed villa was commissioned by Taiwanese real estate company Tomson Group. The total cost of construction amounts to just over €140k and ten further units have already been ordered.
The 3D-printer used in WinSun’s construction projects is 6.6m tall, 10m wide and 150m long and according to Ma Hi Ye, CEO of WinSun, " is the world’s first continuous printing 3D-printer and the largest 3D house printer in the world. "
WinSun estimate that 3D printing technology can save between 30% and 60% of building materials and shortens production times by up to 70% while reducing labour costs by around 80%. Architectural design software is used to integrate different designs, adapting to meet the needs of various building structures without limiting the scope of 3D-printing technology.
These buildings are in full compliance with the relevant national standards
3D-printing in construction projects improves efficiency, reduces waste and makes building sites less hazardous and unattractive, without compromising the integrity of the structure.
Ma Rongguan, chief engineer of China Construction Engineering Bureau said: " These buildings are in full compliance with the relevant national standards. They are safe, reliable and feature a good integration of architecture and decoration. But as there is no specific national standard for 3D-printing architecture, we need to revise and improve such a standard for the future ".
With a whole host of exciting collaborations and commissions in the pipeline, WinSun are set to remain at the top spot for innovation in 3D-printed homebuilding. With housing affordability an issue for many sections of society around the world, 3D-printing could very well present a sustainable and economic solution .
