  • Publication number: 20190218680
    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.

  • Patent number: 9919472
    Abstract: Embodiments are directed to methods of producing devices using modified multi-layer, multi-material electrochemical fabrication processes and/or using a laser cutting processes wherein individual layers or layer groups are formed and then stacked and bonded to produce prototypes or production parts. The methods can reduce the cost and lead time of prototyping when compared with previous multi-layer, multi-material electrochemical fabrication processes and can also reduce the lead time of production quantities, by allowing multiple layers of a multilayer device to be formed simultaneously, e.g. in parallel on the same wafer. Additionally, these methods may be used to extend the maximum height to which parts may practically be made. Finally, the methods allow geometries that are impossible, impractical or difficult to release (e.g. microfluidic devices such as pumps or parts with long, narrow channels) to be fabricated in multiple pieces and then joined after full or partial release.
