How Can 3D Technologies Help Solve Crimes?

It’s a common motif on both movie screens and TVs: a murder is committed and the police investigate to find the culprit. The most modern techniques are used and the culprit is usually quickly arrested. And of course, this has roots in reality. Every year, almost half a million people worldwide lose their lives as a result of deliberate homicide. In 2023, the homicide clearance rate in the United States was around 50%, but these rates vary from country to country. Additionally, 3D technologies are playing an increasingly important role in investigative work and forensic science, generally contributing to its success. Today, very few homicides are not investigated using 3D reconstructions or 3D scanning techniques.

3D forensics is an essential component of modern forensic science. It involves the reconstruction, analysis and processing of criminal acts using 3D tools and human decisions.This autonomous field is increasingly used in criminal law and to solve crimes.To better understand the role of 3D technology in investigative work and the analysis of forensic evidence, we spoke to a number of experts.

The Use of 3D Technologies in Forensic Science

3D technology makes it possible to collect and analyze not only digital media, but also physical evidence, such as printed objects. This can be done via 3D scanning and additive manufacturing.
