Whether intervening in a conflict zone or carrying out disaster relief, soldiers would be able to use the mobile factory to print broken or damaged parts in less than 48 hours, where traditional manufacturing methods typically requires four to six weeks. No tools would be necessary to build the parts, apart from the digital file for the finished product, as well as the material needed to print.  

 

This means that, instead of keeping racks of spare parts in storage, troops would only need to save a digital library of parts for 3D printing; when faced with a previously unseen technical issue, they could design a new digital file and print it as needed.  

Aircraft ducting, replacement lens caps, advanced electronics or medical equipment: there are many examples of products that military personnel are likely to need urgently when in the field, and 3D printing those parts could significantly reduce downtime in a crisis.

Seems like this kind of thing has the potential to be insanely useful down the line.
