Two 3D-printed villas were unveiled in a small village in Binzhou, East China's Shandong province. Compared with traditional houses, these 3D-printed buildings have no bricks, but lumpy cement concrete walls and the whole construction process was managed by a computer program.

Liao Xiaojun, senior engineer of Yingchuang Construction Technique (Shanghai) Co Ltd, said 3D-printed homes can be built faster, for less money and are more environmentally friendly. An entire building can be completed in two months at 5,000 yuan per square meters, he added. 

Three months ago, a Chinese company 3D-printed a two-storey house in Beijing's Tongzhou district in only 45 days. The house, with walls as thick as 0.24 meters, covers an area of 400 square meters. It's claimed that it can withstand an earthquake measuring eight on the Richter scale.
