Honeycomb Heroes: Making Composites for Aerospace

There’s an old saw that if bumblebees were aeronautical engineers they would know they can’t fly. Quite apart from the miracle of their flight, bees also happen to make a lightweight structure of surprising strength, just the sort of thing you’d want if you were building aircraft: honeycomb.

3D-Printed Parts Restore Cars’ Glory

Daimler may be the first vehicle maker to offer 3D-printed replacement parts, but racing enthusiasts and car collectors like Jay Leno have been using additive manufacturing and 3D scanning for many years to replace worn-out parts or to enhance their rides.

Metrology Tools for Medical: A New Focus on Vision Systems

Metrology for medical devices needs to become more capable as those devices get more varied and complex. Manufacturers must inspect dental implants, coronary stents, orthopedic joints, and implanted electronic devices. Surgeons are increasingly using intricate, sometimes one-off, surgical tools. There is also a growing number of consumable items, such as hypodermic needles, made on rapid production lines. They all need ever more precise quality control.

Pilot Composites Workshop Wows Students

Carbon fiber is a magical material. That or similar comments were heard over and over from Roosevelt High School (Seattle) students attending a Composites 101 Workshop held at the National Resource Center for Materials Technology Education (MatEdU), a National Science Foundation Advanced Technological Education (ATE)-sponsored program at Edmonds Community College (Lynnwood, WA).

Conductive Thermoplastics for 3D Printing

As inventive and imaginative as 3D printer technology is, so are the materials that R&D labs have come up with to build parts, including conductive thermoplastics.

New Uses of Noncontact Metrology in Aerospace

Aircraft manufacturers are finding noncontact metrology ever more useful. Its inherent high throughput and decreasing cost is complementing the industry’s ramp-up to meet the world’s appetite for more airplanes.

Smashing Silver Microcubes Toughens Up Materials

Scientists at Rice University (Houston) are smashing tiny silver cubes into a hard target in order to make these metallic microcubes ultrastrong and tough by rearranging their nanostructures upon impact.

3D Laser Gaging Ensures Flawless Engine Fasteners

In an automobile engine, seven types of screws out of approximately 70 are considered critical to achieving the engine’s specified design performance, despite high vibration and heat. The seven include bolts for the cylinder head, crankshaft, con rod, flywheel, and main bearing cap, as well as for the camshaft cap, camshaft sprocket and VCT.

Additive Grows and Has Growing Pains

Additive manufacturing is both growing and coping with growing pains. Companies “have to find ways to streamline” polishing and other finishing processes of 3D printed parts, industry consultant Terry Wohlers said today during a speech at RAPID + TCT.
