The Wire Arc Additive Manufacturing (WAAM) method was developed by Cranfield University in the UK and BAE Systems to produce stable, customized metal parts from titanium, and the researchers say it might one day be suitable for use in aircraft as well.
Taking only 37 hours to output a 1.2-meter-long part, the rapid process might signal the next wave of aeronautical AM.
"We now have the ability to manufacture titanium parts on this scale," says Matt Stevens of BAE Systems. "The next stage is to continue working together to produce more parts and to develop a robust set of processes so we can take this technology and apply it safely and seamlessly into the aerospace industry."
In creating a structure known as a "spar section," the part is used as a structural element of an aircraft's wing. Previous processes would have taken weeks to complete.
"This is an exciting technology with huge potential for the aerospace industry," Williams says. "Cranfield is renowned for its close working relationships with industry partners and this is an excellent example."
