Which IS a step forward. Yes DARPA was involved in the early CNC revolution, looking at data transfer and 'local' manufacture. Back then it was also a 'bandwidth' issue.Old NFOhttps://www.blogger.com/profile/16404197287935017147noreply@blogger.comtag:blogger.com,1999:blog-6244999628674918029.post-7669937047852653742017-08-02T20:35:28.206-05:002017-08-02T20:35:28.206-05:00Swimmer delivery vehicles are normally "wet s...Swimmer delivery vehicles are normally "wet subs", that don't have pressure hulls.

The same could be done to change the look of vehicles or even personnel. <br />As Jeff above says, the difference from the past is doing it by computer instead of manually - I suspect that much of the manual ability has been lost, so much that it isn't an option anymore.Jonathan Hhttps://www.blogger.com/profile/10476185257203343474noreply@blogger.comtag:blogger.com,1999:blog-6244999628674918029.post-26251032708531546492017-08-02T15:46:02.546-05:002017-08-02T15:46:02.546-05:00The Army has been working since at least 2013 (whe...The Army has been working since at least 2013 (when I was assigned to ARCIC). Mostly as a way to simplify at least some parts of the logistics chain.<br /><br />Instead of having to ship various items from the States, and maintain a stockpile against anticipated need, simply set up 3D printers at forward support bases and make the items as needed. Shipping blocks of base material instead of finished items would both reduce and simplify the supply chain.<br /><br />Of course, being able to do the 3D printing in metal rather than plastic will be a big deal.<br />Davehttps://www.blogger.com/profile/16624457882192131051noreply@blogger.comtag:blogger.com,1999:blog-6244999628674918029.post-38932184869469494092017-08-02T15:21:42.599-05:002017-08-02T15:21:42.599-05:00Actually, DARPA was working on this concept back i...Actually, DARPA was working on this concept back in the '80s, but the technology wasn't available to do much more than local CNC machining from archived data sent over a network.<br /><br />Nicholas Negroponte also dealt with it at some length in <i>Being Digital,</i> (1996) using the catch phrase "ship bits, not atoms." <br /><br />Glad to see tech is finally catching up. I'm betting it won't be long before it gets cheap enough for manufacturers to simply keep part description databases online and a local "resource provider" prints (or machines) the part.
