When it comes to military uses for 3D printing, the last two years have been somewhat of a breakthrough window for the technology. In the US, virtually every branch of the military is using 3D printing to some extent, and it doesn’t end there. Just last month we’ve learned that both the British and Israeli militaries are exploring the technology as well. The Israelis are 3D printing on-demand drones, while the British reportedly launched a 3D printed drone from a Naval vessel. As the technology advances, and new applications emerge, this trend will only continue to widen.
