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.

Sometimes succession of a family business from one generation to the next doesn’t always go as planned. Take, for example, Laser Specialists Inc. (Fraser, MI). Incorporated in 1986, the company was positioned at the forefront of laser cutting technology.

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).

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.

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.

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.

Entrepreneurs and existing manufacturers are making 3D printers that automate production of composite parts, and are unique in their design.

Lightweighting is so established it’s now part of marketing for new vehicles. Automakers routinely detail how much less models weigh than their predecessors. General Motors Co., for example, has said a range of its vehicles is anywhere from almost 250 lb (112.5 kg) to 700 lb (315 kg) lighter.

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.

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.
