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.

It is common sense—a vehicle that weighs less requires less fuel to move it. A number of studies show that reducing the mass of a vehicle by 10% results in anywhere from 4.5 to 6% better fuel economy—well worth the effort.
Entrepreneurs and existing manufacturers are making 3D printers that automate production of composite parts, and are unique in their design.
Keeping products clean is becoming a more significant part of manufacturing as standards for cleanliness, deburring, and finish grow more stringent.
From Boeing 787s to new Navy destroyers, fiber-reinforced composites are gaining in use. As production scales up, more-efficient manufacturing remains a focus. One key to that efficiency is tooling for composites. These molds and forms give the final shape to a part, and are often integral to their final curing.
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.
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.
In what shouldn’t be too much of a surprise, challenges for advanced grinding technology from high tech industries range from handling the most difficult-to-machine materials for aerospace jet engine turbines to series production on automotive drive train lines.
The growing need for nano and micro components in the medical industries is challenging manufacturers to continually improve upon their manufacturing processes and take a scientific approach to injection molding and tooling.
Friction welding may be just the recipe for joining lightweight materials
