Additive manufacturing, commonly referred to as “three-dimensional (3D) printing,” refers to a group of technologies able to transform virtual objects (digital blueprints) into physical objects through a process of selectively adding and fusing material in a series of layers, starting from one end of the object to its opposite end. While introducing new capabilities for the manufacturing industry, additive manufacturing also offers possibilities for nefarious use. It is increasingly important to intelligence and law enforcement agencies, for possible source attribution and investigative leads, to recognize when an additive process was used. The purpose of this presentation is discuss the indicators that may be present on evidentiary items to determined if they are consistent with being produced through an additive process, specifically Selected Laser Sintering (SLS).
