1. Customer Spotlight: Northrop Grumman Gets Quick Results From 
Stereolithography

Aircraft maintenance and repair personnel have a tough job – from ensuring that  every part on the aircraft they service can withstand the rigors of flight to  minimizing aircraft downtime while making sure that repair costs are controlled.

Northrop Grumman Corp., El Segundo, Calif., has mastered this balancing act,  largely due to the efforts of its Rapid Prototyping and Manufacturing (RP&M)  team, which uses "stereolithography" – commonly known as "SL" technology – to  create tools.

"We have more than 700 SL-generated tools operating in our production and  maintenance facilities," says Chris Farren, manager of technology applications for  Northrop Grumman's Air Combat Systems. "I'm not talking about molds or  prototypes. We are using stereolithography to create tools that are used  immediately to build or modify our products."
