Shanghai expo park features 3D-printed objects

An expo park featuring 3D-printed objects recently opened in China's Shanghai. Using three dimensional printing technology, the park has turned the imagination into reality. A variety of 3D-printed items are on display including decorations. The park uses recycled waste from steel mills, coal industry, power and chemical plants, and urban waste, as well as sand from deserts, to print everything on display. [Photo: VCG]
