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.

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.

Materials science has opened new possibilities for designers of cars, planes and other products. Metal alloys are now as precisely engineered as they are machined. The result is longer lasting, stronger parts. But with a wider selection of materials comes risk—how can you be sure that one piece of gray metal stock is different than another? Careful warehousing procedures and paperwork only go so far.

It’s easy to become dazed by the continuing stream of buzz words. For those of us in manufacturing, all this buzz creates a sense of impending change, but no clarity on what that change might be. Uncertainty means anxiety.
