Additive Manufacturing (AM) doesn’t offer anything like that economy of scale. However, it avoids the downside of standard manufacturing: a lack of flexibility. Because each unit is built independently, it can easily be modified to suit unique needs or, more broadly, to accommodate improvements or changing fashion. And setting up the production system in the first place is much simpler, because it involves far fewer stages. That’s why Additive Fabrication has been so valuable for producing one-offs such as prototypes and rare replacement parts.
Additive Fabrication Technology is at a tipping point, about to go mainstream in a big way: Among the numerous companies using Additive Technology to ramp up production are GE (jet engines, medical devices, and home appliance parts), Lockheed Martin and Boeing (aerospace and defense), Aurora Flight Sciences (UAVs), Invisalign (dental devices), Google (consumer electronics), and the Dutch company LUXeXcel (lenses for light-emitting diodes, or LEDs). Regarding UAVs, in Iraq and Afghanistan the U.S. military has been using UAVs from the Aurora Flight Sciences company, which prints the entire body of these UAVs —some with wingspans of 132 feet—in one build.
