The Marines are also working on creating a <a href=\"https:\/\/www.defensenews.com\/smr\/equipping-the-warfighter\/2017\/09\/11\/marine-corps-looks-to-3-d-printing-to-make-spare-parts-downrange\/\">3-D printing lab<\/a> to make drones, spare parts and other items on an as-needed basis in the field.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, the U.S. Navy\u2019s Naval Surface Warfare Center and private partners designed a 3-D printed submarine hull, which took between three months and five months to print, at a cost of about $800,000, the Navy stated in a news release.<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, if a 3-D printer is hacked or infected with a virus, hackers could program it to add imperfections in the item it\u2019s printing. Those imperfections could mean the item fails during use, and if those parts are weapons or integral to vehicles, those imperfections can have dangerous consequences, Gupta said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Or consider another scenario. If the temperature of the material being printed is increased or decreased slightly, it changes the chemical structure of the material, potentially weakening the item, Gupta said. Another possible threat would be if small air pockets were added, making the item look secure, but making it structurally weaker.<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When it comes to items like a grenade launcher or a submarine shell, a weaker hull or a misaligned barrel could mean the difference between life and death.<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to the introduction of an imperfection that causes a part of fail, a compromised 3-D printer could potentially give access to classified materials on military networks. If files are stolen, enemy combatants could print the same type of parts used by U.S. service members and use them in combat or use them to train against.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gupta said one way his team at NYU proposes countering these attacks, especially the threat of files being stolen, is to design sensitive pieces with flaws built in \u2014 but provide a \u201cdecoder\u201d separately that fixes the flaw. When printed by the intended owner, the part functions properly; otherwise, it\u2019s useless.<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if an enemy combatant prints a stolen file of a handgun that is designed with this flaw, but without the decoder, \u201cthat gun will probably not fire or explode,\u201d he said.<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ultimately, however, the best approach to 3-D printers is to identify and correct network vulnerabilities before an issue arises.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A hacker could break into a 3-D printer through a weakness when the printer port is opened to a separate network for diagnostics or through other vulnerabilities, Gupta said. A way to prevent this is to have internal subnets, much like the types that exist at national labs, and make sure the 3-D printers can\u2019t be accessed outside that subnet.<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Those early tests for the Marine Corps\u2019 R.A.M.B.O. grenade launcher, for instance, have been done on separate networks until the larger picture of cybersecurity is established with these new tools, said Capt. Chris Wood, co-lead for the Marine Corps\u2019 additive manufacturing projects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAs we continue to quickly test and learn, we\u2019ve kept our printers off of Marine Corps networks so that we can ensure the value of 3-D printing before we undergo the hard work of ensuring cybersecurity of the equipment and software,\u201d Wood said. <br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe Marine Corps does have a robust process for assuring cybersecurity of both new hardware and software, which our 3-D printers would similarly follow. However, our team is also looking into the unique effects and methods of cyberattacks within the realm of 3-D printing processes, materials and design.\u201d<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This approach will assure that, as the military identifies the benefits of utilizing 3-D printers to rapidly address much-needed resources in the field, no network shortcomings have real and lasting implications to service members. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>If a 3-D printer is hacked or infected with a virus, it could be programmed to
