Tokyo Metropolitan Police Department has now used 3D printer to recreate 3D models of crime scenes.

These 3D printed models helps prosecutor to better explain crime scenes, says the police department. Rather than showing the jury crime-scene photographs, prosecutor can now provide detailed 3D models with floor plans and arrangement of furniture.

A 3D printer was introduced to the Institute of Scientific Investigation of Tokyo Metropolitan Police Department in 2010. It was used to print out evidence for cases, such as skulls of the victim in murder cases.
