"You are suddenly not fixed in terms of where you have to manufacture these things. You can manufacture the products [at] whatever base you want, providing you can get a machine there, which means you can also start to support other platforms such as ships and aircraft carriers," Mike Murray, head of airframe integration at BAE Systems, said in a press release.
"And if it's feasible to get machines out on the front line, it also gives improved capability where we wouldn't traditionally have any manufacturing support."
3-D printing has taken off over the past year to create a host of products, from guns to jet engine parts.
BAE said it had already made cost savings of more than £300,000 ($491,364) since adopting the technology and expects to save the RAF more than £1.2 million between now and 2017.
Analysts said the use of 3-D printing will continue to expand, but the extent to which it could be used is unknown.
