Did you know you can 3D print rubber?

3D-printing materials just keep getting better -- and now there are more choices than ever. Watch as Walter Voit, SVP Polymer Materials, Desktop Metal, describes the 3D printing of DuraChain Elastic ToughRubber photopolymers, which produce tough and resilient end-use parts while eliminating the need for a two-part resin. DuraChain photopolymers also demonstrate a long pot life of roughly one year, depending on environmental conditions, making them more suitable for volume production and reducing waste from spoiled, unused material. These materials are offered exclusively on the ETEC Xtreme 8K top-down DLP systems. ETEC is a wholly-owned subsidiary of Desktop Metal.

Best high-speed rotary bearing in THK history

THK has developed its best-performing, high-speed rotary bearing ever: the High-Speed, Double-Row Angular Contact Ring BWH. This rotary bearing has balls aligned inside a cage between the inner and outer rings and is part of the THK Rotary Series, along with the cross-roller ring. The main features of this product are its ability to receive loads in all directions as well as its high rigidity and rotational accuracy, which are equal to that of cross-roller rings. By adopting a new structure to change the rolling elements from rollers to balls, this product achieves the greatest high-speed performance ever offered by THK.

How Nord-Lock washers work

Can you get a design and functional edge with a wedge? In this animated video, Nord-Lock explains the principle behind their original wedge-locking technology, which secures bolted joints even when exposed to severe vibration and dynamic loads. The company says it is impossible for this washer type to loosen unintentionally, due to the wedge created underneath the bolt head and nut.

Cam followers with space-saving polymer outer ring design

The new CFL Series cam follower from IKO International boasts a unique, space-saving outer ring design and polymer layer that exceeds the capabilities of conventional resin-type cam followers. Many conventional cam followers press-fit a layer of resin onto the unit's standard outer ring to maintain radial load capacity and provide quiet, clean, and durable operation. However, this thicker assembly makes it difficult to fit into constrained spaces. The CFL Series significantly improves on this design with a polymer layer that is molded directly onto the IKO exclusive thin-walled steel outer ring. This construction solves the dilemma of being able to install a cam follower with special polymers, offering self-lubricating and shock-absorbing properties into existing applications.

Airbus flies a fully automated helicopter with a tablet

Airbus has successfully tested a new simplified human machine interface (HMI) along with advanced autonomous features through a project code named "Vertex." The technologies, developed by Airbus UpNext, are controlled by a touchscreen tablet and aim to "simplify mission preparation and management, reduce helicopter pilot workload, and further increase safety."

Pilots monitor the newly developed Vertex HMI (autonomous pilot) on Airbus Helicopters' FlightLab.

 

 

Airbus Helicopters' FlightLab -- a flying copter laboratory -- flew fully automated from liftoff, taxi, takeoff, cruise, approach, and then landing during a one-hour test flight by following a predefined route. During this flight, the pilot monitored the new system, which is able to detect unforeseen obstacles and automatically recalculate a safe flight path. Whenever necessary, the pilot can easily override the controls through the tablet and resume the mission. The flight test period ran from Oct. 27 to Nov. 22 at the Airbus Helicopters' facility in Marignane, France.

"This successful demonstration of a fully autonomous flight from takeoff to landing is a great step towards the reduced pilot workload and simplified HMI that the Airbus Urban Air Mobility team intends to implement on CityAirbus NextGen. It could also have immediate applications for helicopters in low-level flights close to obstacles thanks to the information provided by the lidars on board," said Michael Augello, CEO of Airbus UpNext. CityAirbus NextGen is an all-electric, four-seat vertical take-off and landing (eVTOL) prototype being developed by Airbus.

Airbus Helicopters will continue to mature the different technologies that comprise Vertex: vision-based sensors and algorithms for situational awareness and obstacle detection, fly-by-wire for enhanced auto-pilot, and an advanced HMI in the form of a touchscreen and head-worn display for in-flight monitoring and control.
