I think 3D printing has many potential military uses and these two stories demonstrate the potential.
Researchers at the University of Sheffield have created a low cost disposable unmanned aircraft making extensive use of 3D printing[browser-shot width=”600″ url=”http://www.aerospace-technology.com/news/newsuk-researchers-create-3d-printed-disposable-uav-4207929″]
3D printing unmanned aircraft is not new but it is an interesting story anyway.
And this one, looking at contour crafting, or 3D printing buildings. Although the details are a bit vague, the potential for military building is obvious[browser-shot width=”600″ url=”http://www.3ders.org/articles/20140401-10-completely-3d-printed-houses-appears-in-shanghai-built-in-a-day.html”]
This from me looks at the potential for printing or 3D contour crafting in military engineering[browser-shot width=”600″ url=”https://www.thinkdefence.co.uk/2012/08/printing-fortifications-buildings-and-bridges/”]
