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.

New work materials are developed continually to improve the capabilities of finished parts, making them lighter and stronger, among other properties. When these materials catch on, cutting tools must adapt to their often challenging properties.

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.

A new breed of turbochargers constructed of super tough alloys operates at higher temperatures and rotational speeds than ever before, resulting in greatly increased output in a smaller package for gas and diesel engines alike.

You don’t have to look too far to find the reasons for the growth of fiber lasers for production applications. On price per watt, beam quality, electrical consumption, and maintainability required, fiber lasers typically score the lowest on the cost side and very high on the performance side.

(Roxbury Twp., NJ) Legionella, the bacteria that causes potentially fatal Legionnaire’s Disease, and other strains of deadly pathogens that are hosted by some cooling towers, have been substantially reduced by the development of a unique anti-microbial HDPE material introduced by Delta Cooling Towers (deltacooling.com) on September 1, 2016.

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

Researchers at Rice University (Houston) have discovered a titanium-gold (TiAu3) alloy that is harder than most steels and may be an optimal choice for use in orthopedic joint replacement surgery.

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.
