As we all know, the application range of 3D printing technology is very wide. There are stories about 3D printing medical applications almost every day, and the influence in fashion, architecture and other fields is increasing. Sometimes even interesting applications are created in unexpected places. For example, the FBI recently showed how 3D printing technology can help forensic doctors confirm unidentified wills.
In the United States, about 4,400 people are found every year, but they are not sure, and more than 1,000 of them are still unable to determine their identity even after one year. This time, the FBI rebuilt the face of the deceased through 3D printing technology, and then let the forensic doctor conduct in-depth research and analysis, and finally determine the identity of the deceased.
However, the process of facial reconstruction is complicated. First, the skull needs to be sent to the laboratory for 3D scanning, and then printed in 3D. Then the forensic doctor will analyze a report on the age, sex and pedigree of the deceased according to the actual situation.
Bailey entered the US Federal Bureau of Investigation 14 years ago, and through her ongoing research, she has now become an expert in the study of skull characteristics. “I read many anthropologists' reports, and I found that each face is different, and each skull is different. I can know a person to a certain extent through the proportion of their faces,†she said.
When the 3D printed skull is completed, Bailey will clay and sculpted it, eventually forming a sculpture that is close to the true look. The development of 3D printing facial reconstruction technology will greatly help the police to confirm the identity of the missing person.
