Uncharted: How 3D Printing Experiments Delivered A Better Power Plant

Maggie Sieger

Many of Kassy Hart’s first attempts at 3D printing didn’t end well.
Back in 2015, Hart was trying to print a special metal probe from a cobalt-chrome alloy at GE Power’s Advanced Manufacturing Works in Greenville, South Carolina. 3D printers build parts, step by tiny step, by fusing together superthin layers of fine metal powder with a laser or other powerful energy source.

"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.

In October, engineers at Avio Aero, a GE Aviation company, used a futuristic process called cold spray to repair a gearbox on the GE90, the largest and most powerful jet in the world. The technology uses a special supersonic nozzle attached to a robotic arm. The nozzle shoots a barrage of tiny metal specks at four times the speed of sound at metal components like the gearbox.

Pedal To The Metal: This Engineer Wants To Supercharge 3D Printing With Powerful Lasers

Todd Alhart
December 14, 2017
3D printing has come a long way over the past 20 years. Engineers and designers already print jewelry, airplane parts, bone implants, and even toothbrushes directly from a computer file, layer by layer, using a laser or an electron beam.

When Mohammad Ehteshami talks about 3D printing, he often mentions his “epiphany of disruption,” the moment he realized that additive manufacturing will upend how companies design and make things. “I remember that day like today,” Ehteshami said. “I was excited but also disturbed. I knew that we found a solution, but I also saw that this technology could eliminate what we’ve done for years and years and put a lot of pressure on our financial model.”

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

Tomas Kellner
November 13, 2017

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

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.
