Airmen at Travis U.S. Air Force Base in California are implementing innovative strategies to reduce man hours and increase mission effectiveness and over the past several months, the base has implemented a variety of innovations including 3D printing and 3D scanning.
Cultivating a culture of innovation is essential to mission success, said Col. Matthew Leard, 60th Air Mobility Wing vice commander. “At Travis (AFB), Airmen are empowered to identify and solve problems at their level, rapidly,” he said. “We want Airmen to think big and try the ideas others say will never work. It does not always have to be proven technology or have a business case. Let’s just try it, who knows it may just work.”
The innovations under way at Travis AFB were made possible when the Air Force distributed $64 million in Squadron Innovation Funds in an effort to increase readiness, reduce cost, save time and enhance lethality of the force. In October, Travis AFB procured a Creaform HandyScan 700 3D hand scanner capable of producing three-dimensional representations of aircraft parts. The device has also been used to inspect aircraft damage.
“The scanner displays the deepest part of a dent to the nearest thousandth of an inch,” said Master Sgt. Christopher Smithling, 60th Maintenance Squadron assistant section chief for aircraft structural maintenance. “The scanner can identify the shape of a dent, as well as if it’s sharp, smooth or round, which allows us to give our engineers a better damage analysis than we could before.”
Smithling said the scanner was first used in November to inspect the landing gear of a C-17 Globemaster III after a bird strike, and over the past month, has greatly reduced the time required to complete damage inspections.
“One of our C-5 aircraft went through a hail storm in 2013 and we found many dents on all the panels,” he said. “We’ve performed an inspection of this aircraft every 180 days and we’ve had to measure every dent that’s still on the wing’s surface. The first few times we did that, it took us 48 hours. We had that C-5 in our hangar last week and we were able to inspect the four primary structural panels in 30 minutes.”
The 60th MXS is also in the process of procuring two 3D printers, one polymer printer and one metal printer, so they can reproduce aircraft parts.
“With the two additive manufacturing units, we will be able to grab any aircraft part, scan it, and within four to eight hours, we will have a true 3D drawing of it that we can send to the additive manufacturing unit to print it,” Smithling said. That capability, he said, will decrease the time Travis AFB aircraft are out of service.
“Right now, we could have one of our aircraft down for about 48 hours while we try to get the part it needs,” he said. “Once we have this additive manufacturing capability in place, we will likely be able to print and replace parts in a few hours and return our aircraft to flying status much quicker.”
