Research Topic Description, including Problem Statement:
Rapidly growing numbers of firearms based on fabricated parts from additive manufacturing (AM) and three-dimensional printing (3DP) machines are challenging the ability of traditional forensic firearms/toolmark examinations to determine class and individual characteristics. With the proliferation of AM/3DP machines, lowering costs, and their increasing use in commercial manufacturing and in everyday home use, law enforcement will encounter parts and products produced by these machines. With these encounters, firearms/toolmarks examiners (FTE) will be asked to determine, if possible, the type and source for an AM part.
The currently limited understanding of nozzle manufacturing, toolmarks present, effects of wear, and life expectancy of AM/3DP-produced firearms by FTEs calls for more research into AM to determine if individual characteristics exist and persist and if they can provide evidence of a common source.
Utilization of traditional forensic firearms/toolmark examinations to determine class and individual characteristics from AM to determine a common source.
Relevance to the Intelligence Community:
With increased use of AM as a substitute for traditional manufacturing, the Intelligence Community will need to be able to recognize the method being utilized and potentially determine a common source (e.g., a specific nozzle produced an AM good, as determined by the persistence of individual characteristics from manufacturing toolmarks).
Key Words: Additive Manufacturing, 3D Printing, Fused Filament Fabrication (FFF), Fused Depositional Modeling (FDM), Material Extrusion, Nozzles, Toolmark Identification
