The Forbidden City, the palace once home to the emperors of China, was built by workers sliding giant stones for miles on slippery paths of wet ice, researchers have found.
The emperors of China lived in the Forbidden City, located in the heart of Beijing, for nearly 500 years, during China’s final two imperial dynasties, the Ming Dynasty and the Qing Dynasty. Vast numbers of huge stones were mined and transported there for its construction in the 15th and 16th centuries. The heaviest of these giant boulders, aptly named the Large Stone Carving, now weighs more than 220 tons (200 metric tons) but once weighed more than 330 tons (300 metric tons). Read more.
Loughborough University designers are to use 3D printing to help restore ancient artefacts from Beijing’s Forbidden City.
The Forbidden City’s Palace Museum is undergoing major restoration work, involving thousands of individual relics, funded by the Chinese government. Traditionally, objects needed to be measured, photographed and repaired using manual techniques — an extremely time consuming and expensive task.
However, Loughborough Design School PhD student Fangjin Zhang and colleagues have been investigating the use of 3D printing within the context of restoration in order to save money.
The team is capturing the shape of the original objects using laser or optical scanners then cleaning up the data using reverse engineering techniques. Read more.
