3D-printed ghost guns may now have a way to be traced to their source — Australian researchers correctly identify 26 out of 28 printed PLA samples to their filament product

A study published on October 22 in the journal Forensic Science International reports that researchers from Curtin University in Perth, Australia, have developed a forensic method to analyze 3D-printed PLA parts and match them to their respective filament, correctly matching 26 out of 28 samples of PLA. This potentially provides a way to link seized 3D-printed “ghost-guns” with other seized filament, allowing police
