Summary:
- This article discusses the use of 3D printing technology to create untraceable "ghost guns" that lack serial numbers and are difficult for law enforcement to track.
- Researchers have discovered that 3D-printed parts can leave behind unique "fingerprints" that could potentially be used to identify the specific 3D printer used to create the parts.
- The ability to trace 3D-printed gun parts back to their source could help law enforcement investigate and prevent the proliferation of these untraceable firearms.
