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.

There are pros and cons to using a scaffold for tissue printing. Ultimately, it’s not a matter of choosing one method over the other, but using them to complement each other.
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.
An early pioneer in the field of additive manufacturing (AM), the story of Carl R. Deckard, PhD, ME, is an example of the University of Texas motto: “What Starts Here Changes the World.”
Keeping products clean is becoming a more significant part of manufacturing as standards for cleanliness, deburring, and finish grow more stringent.
When a contract manufacturer sees an opportunity in the competitive aerospace market, it sets priorities aimed at providing the right combination of processes required to meet the industry’s exacting demands. Precision machining and finishing, parts inspection, and, of course, certifications from OEMs and industry alliances are at the top of the list. Increasingly, aerospace suppliers like Volvo Aero Connecticut (Newington, CT) are benefiting from five-axis machining, advanced CNC controls, motors and drives, robotic deburring, and on-machine inspection for a competitive advantage.
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.
Automation in manufacturing is more important than ever, reducing costs and improving quality. While it is important in assembling cars, machining engines, or drilling holes in airframes, is it important to metrology operations as well? “Absolutely,” explained Michael Kleemann, engineering manager VRSI (Plymouth, MI).
Solid-state laser technology has matured, leading to development of new, cost-effective welding applications, such as hybrid welding
Oerlikon announced today that it will be building a new state-of-the-art manufacturing facility in Plymouth Township, Michigan, USA, dedicated to producing advanced materials for additive manufacturing and high-end surface coatings.
