Gears have been a vital component since the invention of rotating machinery. Because of their force-multiplying characteristics, they were used by early engineers to lift building materials. Gears were also used to hoist ship anchors and for catapult pretensioning. Another application was wind and water-wheel machinery, as the rotational speed could be increased or decreased as required for the specific machine to be powered.
This 20-minute video shows how rockets are 3D printed. This process saves on up-front tooling, enables rapid iteration, decreases part count and facilitates radically new designs.
Sintavia LLC developed proprietary printing technology for GRCop-42, the preferred copper alloy used by NASA and private space-flight companies for rocket thrust chamber assemblies.

Shell’s in-house 3D-printing capability started 10 years ago in 2011 with a metal laser-printing machine to fabricate testing equipment for lab experiments at the Shell Technology Centre Amsterdam (STCA). Today, the company has about 15 metal, polymer and ceramic 3D printers at its technology centers in Amsterdam and Bangalore.
In an effort to reduce dependence on imported materials and technology, especially from China, India is investing in a battery technology that uses aluminum rather than lithium as the key ingredient.
Mining company BHP will supply electric-vehicle manufacturer Tesla Inc. with nickel from its Nickel West asset in Western Australia. Nickel is a key metal used to manufacture Tesla’s battery technology. BHP will also collaborate with Tesla on energy storage solutions to identify opportunities to lower carbon emissions in their respective operations through increased use of renewable energy paired with battery storage.
