Secret Weapon: This Supersonic Blaster Rebuilds Jet Parts With Flying Powder

Yari Bovalino
November 15, 2017
A few years ago, scientists working in GE labs in upstate New York came up with a cool idea for fixing broken parts. Literally. Calling the approach “cold spray,” they shot tiny metal grains from a supersonic nozzle at aircraft engine blades to add new material to them without changing their properties.

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

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.

The Aviator: How A Young Pilot Became A Top-Flight 3D-Printing Engineer

Maggie Sieger

At 15, Josh Mook got a job refueling planes and handling bags at a small airport near his hometown of Louisville, Kentucky. He’d work eight hours a day after school, then blow his earnings every Saturday taking flying lessons. “I couldn’t even drive myself there,” Mook recalls. “But I was flying solo.”

Pedal to the Metal: New Metal 3D Printing Systems Are Picking Up Speed

Duann Scott Redshift
August 11, 2017

After 20 years of iteration on the same basic additive-manufacturing technologies for metal, a new wave of innovation is emerging. Lower-cost, safer processes are replacing the old ways of doing things, offering vastly different material properties through resolution, surface quality and design freedom.

Dream Come True: How Two Australian Dentists 3D Printed A Fix For Apnea

Some 34 men out of 100 suffer from sleep apnea, and Dr. Christopher Hart was one of them. The condition, which is much less frequently diagnosed in women, blocks the airways and causes people to temporarily stop breathing. It also can jolt them awake several times during the night. The most common treatment involves a method called Continuous Positive Airways Pressure or CPAP, which requires sleeping with a bedside pump that forces air through a mask worn over the mouth and nose.

5 Coolest Things On Earth This Week

Tomas Kellner
June 09, 2017
Engineers in the U.S. built a tiny cyber-backpack that allows them to control a dragonfly in flight, their colleagues at MIT equipped a robot with sensors that gave it a sense of touch and their colleagues in Rhode Island and China designed a heat-resistant ceramic that can be squished like a marshmallow but survive temperatures up to 800 degrees Celsius. That’s hot!

Logistics For A 3D Printed World: The Democratization Of Manufacturing

Alan Amling Ups
June 09, 2017

From hearing aids to jet engines, 3D printing is revolutionizing the world of manufacturing. How will commerce change when thousands of products, from cell phones to blenders, are customizable? Even though 3D printing is a 30-year-old technology, we’re just scratching the surface of where additive manufacturing will take us, writes Alan Amling, vice president of corporate strategy for UPS.

 

 

Of all the ways 3D printing will change the world, the democratization of manufacturing is perhaps the most important.
