How does this compact 3D printer really work to make business better?

According to FBI statistics, there were 635,155 missing person reports filed in 2014, with 634,367 eventually listed as solved. That leaves 788 individuals that were never found, or at least haven’t been found yet. Unfortunately, a fair number of those missing individuals will die before being found and their remains aren’t always recovered in a place or time conducive to identification efforts.

If you’ve ever watched shows like Bones or CSI, you’ve no doubt seen scenes where forensic wizards reconstruct faces to match unidentified remains, but in the real world, it isn’t as simple as pushing a few buttons. A recent effort involving coordination between Florida law enforcement departments and the University of Southern Florida (USF) used 3D printing as one method of assisting police with identification.

Dubbed, “The Art of Forensics,” students and faculty at USF’s Institute of Forensic Anthropology and Applied Science were given access to materials belonging to nine different unidentified bodies, including plastic skulls. The skulls were the result of 3D scans of actual remains that were then built using a 3D printer. Using replicas allows for facial reconstruction work without tampering with the original remains.

Students were then asked to reconstruct the images of the unidentified individuals, using the skulls as a template. The reconstruction process works in a manner similar to 3D printing by creating the face in layers. The process begins by creating a layer of clay muscle tissue over the skull, then adding a layer of facial tissue, followed by a small touches to give each reconstruction at least the semblance of a real face.

The only liberty allowed the reconstruction artists is in hair style. The resulting faces were run in local newspapers and listed in the National Missing and Unidentified Persons database.

3D printing as a tool is becoming more valued by forensics experts across the world, many times replacing older technologies for its ability to produce replicas without destroying original evidence. Another example is shoe molds. Using a 3D scanner to create digital records of footprints at a crime scene is quicker and less invasive than plaster molds.
