China: Recycled Concrete Houses 3D-Printed in 24 Hours
May 6, 2014
A Chinese construction firm based in Shanghai has succeeded in building 10 houses each measuring 200 square metres in 24 hours by using an enormous 3D printer.
The houses are all eco-friendly and constructed from 3D-printed building blocks made from layers of recycled construction waste and glass fibre and mixed with cement.
Each home costs less than £3,000 to build.
WinSun Decoration Design Engineering spent 20 million Yuan (£1.9m) and 12 years to develop a 3D printer 6.6 metres tall, 10 metres wide and 150 metres long.
Large 3D printers have been in existence for several years and have been used to make plane parts and prototypes.
"We purchased parts for the printer overseas, and assembled the machine in a factory in Suzhou. Such a new type of 3D-printed structure is environment-friendly and cost-effective," said the 3D-printer's inventor, Winsun CEO Ma Yihe.
