Abstract
A counterfeiting deterrent device according to one implementation of the disclosure includes a plurality of layers formed by an additive process. Each of the layers may have a thickness of less than 100 microns. At least one of the layers has a series of indentations formed in an outer edge of the layer such that the indentations can be observed to verify that the device originated from a predetermined source. According to another implementation, a counterfeiting deterrent device includes at least one raised layer having outer edges in the shape of a logo. A light source is configured and arranged to shine a light through a slit in a substrate layer of the device and past an intermediate layer to light up the outer edge of the raised layer. The layers of the device are formed by an additive process and have a thickness of less than 100 microns each.
