Physical and Chemical Trace Evidence from 3D-Printed Firearms

The purpose of this research project is to provide criminal justice practitioners the tools they need to investigate, solve, and prosecute crimes committed with a 3D-printed firearm.

The specific objectives of this research are to 1) determine tool mark and impression features on cartridge cases and bullets associated with being fired by a 3D-printed firearm; 2) develop a rapid method to detect and identify a wide range of polymers that can be used to manufacture 3D-prinated firearms focusing on direct analysis in real time mass spectrometry; and 3) create a searchable library of the spectral signatures of those polymers for use in forensic examinations.

"Note: This project contains a research and/or development component, as defined in applicable law," and complies with Part 200 Uniform Requirements - 2 CFR 200.210(a)(14).
