from gizmodo.com: New advances in 3D printing are making it not only possible but also viable to manufacture cheap, print-on-demand, disposable drones designed simply to soar off over the horizon and never come back. Some British engineers did just that, and this is only the beginning.

The team hails from the Advanced Manufacturing Research Center (AMRC) at the University of Sheffield, where they’re exploring innovative ways to 3D-print complex designs. They built their disposable drone, a five-foot-wide aircraft — made of just nine parts — that looks like a tiny stealth bomber, using a technique called fused deposition modelling. This additive manufacturing technique has been around since the 1980s, but has recently become faster and cheaper thanks to improved design processes.
 
The ultimate vision, as sUAS describes it, is for “cheap and potentially disposable UAVs that could be built and deployed in remote situations potentially within as little as 24 hours.” Forward-operating teams equipped with 3D printers could thus generate their own semi-autonomous micro air force squadrons or airborne surveillance swarms, a kind of first-strike desktop printing team hurling disposable drones into the sky.
