Ship Shapes: New 3D Printing Research Aims To Rejuvenate Navy Gear

Dorothy Pomerantz
May 02, 2018
"When a warship breaks down, the Navy needs to get it running again right away. A new GE Global Research program is developing ways to scan and 3D-print replacement parts out of metal melted with lasers, to get them back to the ship as quickly as possible.
The Navy cares about this technology because its fleet is aging, with ships dating back decades. Many of the parts that make up these vessels are so old that substitutes are no longer manufactured, and replacement parts have to be custom-designed.

Frank Herzog was still in elementary school in the historic Bavarian city of Bamberg when he fell in love — with metals. So ardent was his passion that he later quit high school to pursue it. “I was young when I realized that I loved the material,” he says.

The Northern Italian town of Cameri could be easily mistaken for a quiet farming commune. But take a short ride through the rolling fields of the fertile Po Valley that surround it and you’ll discover a startling contrast.

Added Value: 3D Printing Program Helps Teachers Cultivate Next Generation Of Engineers

Dorothy Pomerantz
February 23, 2018
Two years ago, Bart Prorok, a professor of materials engineering at Auburn University in Alabama, decided his students needed to learn about additive manufacturing, also known as 3D printing, if they were going to be prepared for the jobs of tomorrow. But buying a commercial metal additive manufacturing machine was out of the question because of the price. Those machines can cost hundreds of thousands, even millions, of dollars apiece.

GE engineers recently built and tested 30 different prototypes of a complex, football-size jet engine component. Thanks to cutting-edge 3D-printing technology, they were able to reach the perfect design in just 12 weeks. This is remarkable considering it would take several years to iterate on that many designs using traditional casting methods.

Tour De Force: This Slovak Company Is 3D-Printing Bespoke Electric Mountain Bikes

Maggie Sieger
January 05, 2018
Patrik Paul loved riding his bike everywhere growing up in the Slovak capital Bratislava. He dreamed of the perfect mountain bike — one that exactly matched his center of gravity and perfectly gripped the track on curves. But such a bike simply wasn’t within his reach. The costs and technology for that level of customization would make it prohibitively expensive.

Fired Up: GE Successfully Tested Its Advanced Turboprop Engine With 3D-Printed Parts

Tomas Kellner

"Stephen Erickson was just 13 years old when he fell in love with planes — inside a Boston movie theater. He was watching aircraft mechanic Joe Patroni, played by George Kennedy in the original “Airport” movie, extricate a Boeing jet full of worried passengers from a snowdrift. “That moment was the spark that changed my life,” he says. “I wanted to build aircraft engines.” He enrolled in a technical school and joined GE Aviation, where he has become an ace test engineer — a real-world Patroni.

An Epiphany Of Disruption: GE Additive Chief Explains How 3D Printing Will Upend Manufacturing

Tomas Kellner

Jet engines are large and complicated machines. But sometimes surprisingly small parts can make a big difference in how they work.
A decade ago, engineers at CFM International, a joint venture between GE Aviation and France’s Safran Aircraft Engines, started designing a new, fuel-efficient jet engine for single-aisle passenger planes — the aircraft industry’s biggest market and one of its most lucrative.

Laser Focus: Computer Vision and Machine Learning Are Speeding Up 3D Printing

Todd Alhart
October 19, 2017
Scientists working at GE labs in upstate New York have spent decades building computer vision systems that can study diseased tissue, and hunt for microscopic cracks in machine parts and other features often invisible to the naked eye. “Computer vision can be used to find things we either can’t see or may not know to look for,” says Joseph Vinciquerra, who runs the Additive Research Lab at GE Global Research in Niskayuna, New York.
