For the past decade, aerospace manufacturers have used additive printing to prototype select parts.  For example, the global aerospace industry received a jolt earlier this year when AVIC Heavy Machinery Co. Ltd. of China displayed a 5-meter-long (16.4-foot-long) titanium part fabricated with additive manufacturing, also known as 3-D printing.The process is fast and affordable.

Now, printed aircraft parts have flown for the first time in the UK on board a Tornado jet. Engineers at BAE Systems, who are responsible for the mix of plastic, protective covers and metal support struts, said the components demonstrated how 3-D printing could reduce costs and increase strength compared to conventionally made parts. The latest development is also set to pave the way for their wider use in aerospace.
