The crime scene investigations in South Korea will now be made with the help of 3D printing. Starting to manufacture crime scene replicas with 3D, South Korea saves significant time.
Additive manufacturing is now used so widely that the fact that it entered to forensic researches is not very suprising. Offering both quality and time saving, 3D technology is now the helper of South Korean crime investigations.
Hong Kong’s police briefing support unit was established in 1988, and over the years it has 
built a total of 18 different scale models of buildings and aircrafts. These models provide a clear visualization of particular situations and the environments in which they took place. A fatal gun attack in Kowloon Bay in 2014, a hot air balloon crash in 2013, and a 2010 hostage situation on a bus in Manila are just three of the incidents whose investigations required the building of these scale models. According to Senior Inspector Chan Shun-wai, construction of a model by hand can take up to a week to complete. This process can now be greatly accelerated with the help of newly purchased 3D printers, which cost around HK $10,000 each.
As well as helping with investigations, the scale models that are produced by the briefing support unit also play a crucial role in the courtroom. They allow judges to better understand the layout of a crime scene, and the details of witnesses’ testimonies can be easily tested and examined. The unit also constructs models that are used by Hong Kong’s counterterrorism squad, in order to plan potential scenarios and provide information about incidents.
