Australian Researchers Find Way to Trace 3D Printed Ghost Guns Using Chemical Fingerprints

Breaking the Untraceable Myth

3D-printed ghost guns have long been considered nearly impossible to trace. But new research from Australia suggests these weapons may not be as untraceable as criminals believe.

The Challenge with Ghost Guns

Traditional firearms forensics relies heavily on toolmarks unique impressions left on bullets and cartridge cases. However, 3D-printed guns often produce inconsistent or absent toolmarks, making conventional methods ineffective.

A Chemical Approach

The Curtin team studied the chemical composition of materials using infrared spectroscopy paired with statistical analysis. They analyzed 67 different filament products available on the Australian market.

Real-World Implications

Last October, an Australian Border Force operation uncovered 281 3D-printed firearms or components. 3D-printed components can also be combined with hardware store parts to create hybrid weapons.

Legislative Response

California has proposed AB 2047, requiring 3D printers to screen what they are asked to produce. This research offers a complementary approach for tracing the source of illicit prints.
