#Crime Solving with #3D Printing

Printing has come a long way from hand-copied manuscripts to printing 3D objects. Printing has changed our world from ignorance to fully-informed through the benefit of printed books.

There are many things we can do with 3D printing. One of them is solving crimes. In the world of law enforcement, the evidence is the key to solving any crime. It is impossible to solve a crime without any evidence. 3D printing is changing how evidence is gathered, viewed, and examined.

Crime-solving is an art in and of itself. The evidence gathered is like pieces of a jigsaw puzzle. All the pieces should fit exactly for the investigators to see the whole picture.

Gathering evidence is not an easy task. Investigators will try to eliminate items or prints that were not there after the crime took place. After doing that then the gathering of evidence can begin. Taking pictures of the crime scene is usually the first thing they do before removing any physical evidence from the scene. Sometimes, there is a piece of evidence that cannot be carried to the laboratory, like a wall, a tree, a floor, or other permanent objects at the crime scene. In these instances, 3D laser scanning can be utilized. The 3D images that are acquired through the 3D laser device can then be printed in a 3D printer on a smaller scale. The investigators can even choose a specific spot to print with the 3D printer for them to examine the evidence more precisely.


There are occasions when the body of the deceased victim cannot be examined any longer due to family’s desire or the victim’s wishes to be cremated immediately after death. There may also be cases wherein the crime was committed decades ago and the only evidence left is the victim’s pictures during the investigation. In this scenario, investigators can use a specialized computer program where it can create a 3D image of the victim using all the available pictures from the crime scene or the victim’s body. The investigators can then print whatever part of the victim’s body they wanted to examine after the image is formed. They can determine how the injuries were incurred through the printed 3D image.


In some instances, the evidence needs to be replicated with a 3D printer so that the investigators can check their theories regarding how the crime took place. Buying expensive antiques or appliances in order to make an experiment of their hypothesis may hinder their ability to solve the crime. Printing a 3D image of the object and covering it in similar material of the evidence may give them a chance to relive the scenario without too much cost. They can create multiple 3D images to see different angles of what may have happened. They may even increase or decrease the size of the object with the use of a 3D printer and this will give them a better understanding of the evidence.


The use of 3D printing for solving crimes has just begun. This technology will greatly increase the capability of law enforcement to determine what really happened in a crime. This procedure will also help determine whether the suspected individual is the culprit or just an innocent person.
