A funeral home in Shanghai is using 3D printing to reconstruct the faces of people who may have been badly injured when they died.

For many in China seeing a loved one's dead body is a fundamental part of saying goodbye, but for those killed in natural disasters or accidents the deceased person's face may be unrecognisable to their families.

Traditionally, wax and putty have been used to reconstruct a person's face, but the process can take up to two weeks. The 3D printing method used by the Shanghai Longhua Funeral Home takes just one day.
