3D Printing Used To Restore China’s Forbidden City
|Loughborough University designers will be using the latest 3D digital technologies to help restore ancient artefacts from the Palace Museum in Beijing. Using conventional methods, the objects need to be measured, photographed and repaired using manual techniques – an extremely time-consuming and expensive task. |
The museum, also known as the Forbidden City, is currently undertaking major renovation work funded by the Chinese Government. This is a huge project that involves thousands of individual historic relics.
Using conventional methods, the objects need to be measured, photographed and repaired using manual techniques – an extremely time-consuming and expensive task. However recent research at Loughborough Design School aims to speed up the project, saving time and money.
Since 2009, Loughborough Design School PhD student Fangjin Zhang and colleagues have been investigating the use of 3D printing and other digital technologies within the sculptural and archaeological restoration fields.
3D printing allows physical objects to be built directly from 3D computer-aided-design (CAD) data without the need for tooling and with minimal human intervention. It is already widely used in manufacturing industries and for medical models.

The application of this method to archaeological artefacts requires the shape of the original objects to be ‘captured’ using laser or optical scanners, and the data to be ‘cleaned-up’ using reverse engineering techniques. Through this process damaged areas can be digitally restored ready for the 3D printing process. This has been possible for some time, but now Miss Zhang is developing a formalised approach tailored specifically to the restoration of historic artefacts. The process has already been applied to a range of objects from the Forbidden City and elsewhere.
The Director of the Ancient Architecture Department in the Palace Museum and member of the China Association for Preservation Technology of Cultural Relics, Mr Shiwei Wang added: “This is a good start, and we hope the research on these applications will continue as the prospects are very broad.”
“We are delighted to be working with the museum, using this very modern and innovative technique to restore and safeguard some of China’s most important artefacts,” said Loughborough Design School’s Dr Ian Campbell. “There is real scope for this technique to be used in museums across the world.”
