  • Ballistic barrel cleaning shell
    Patent number: 10578408
    Abstract: A bore cleaning device is configured to clean a bore of a firearm. The device includes a cylindrically shaped cleaning pad including a solid, non-hollow core. The device further includes a propellant providing a force to push the cleaning pad down the bore of the firearm and a payload located in a bore-forward position of the cleaning pad. The device can optionally include a lower charge cap situated between the propellant and the cleaning pad.
    Type: Grant

  • Three-dimensional printing using fast STL file conversion
    Patent number: 10061284
    Abstract: Methods are provided for solid free-form fabrication of an article without using a slice stack file quickly and efficiently—in terms of computational resources—converting STL files representing an article or articles to be built by SFFF without the use of a conventional slicing program. An application program interface (“API”) is used to generate a bitmap corresponding to each particular layer of the article that is to be printed directly from the article's STL file. This conversion may done essentially in real time immediately before the particular layer is to be printed. The bitmap is used in configuring the printing instructions for the SFFF printing mechanism to print that particular layer.
