More than one crime, including multiple murders, has been solved with help from 3D printing, as the technology can help recreate forensic evidence. But in a new study entitled "A Preliminary Investigation into the Accuracy of 3D Modeling and 3D Printing in Forensic Anthropology Evidence Reconstruction," a team of researchers examines just how impactful 3D printing and 3D modeling actually are in solving cases.
The researchers affirm that 3D printed evidence has been useful in several court scenarios. 3D printed replicas of bones can be more effective than photographs at showing the nature of injuries to victims, but while there is quite a bit of circumstantial evidence demonstrating that this is the case, there is still a lack of published empirical evidence. This study aims to change that.
Recommendations include employing the highest CT scan resolution possible, using a high/hard CT reconstruction filter, applying an appropriate degree of surface smoothing, and using a 3D printer that does not require support structures. The researchers conclude that 3D printed forensic samples are indeed a valid method of providing evidence in court.
