U.S. Army gets world's largest metal 3D printer
The U.S. Army's new Jointless Hull machine (made with the aim of 3D printing a tank hull in one piece) is the world's largest additive and subtractive manufacturing apparatus. It 3D prints parts up to 30 ft long that are forging-level quality using a new technology called additive friction stir deposition.

Nuclear battery claimed to power small devices for 50 years without charging
A Chinese company claims that its miniature atomic energy batteries can generate electricity stably and autonomously for 50 years without the need for charging or maintenance. An atomic energy battery could one day power cell phones that never need charging, and the battery will not catch fire or explode.

Self-eating rocket engine burns itself for extra fuel
University of Glasgow engineers in Scotland have built and fired the first unsupported "autophage" rocket engine that consumes parts of its own body for fuel. The design concept was first patented nearly 100 years ago but never successfully built.

Image - Innovative way to take up tolerances!
Innovative way to take up tolerances!
Smalley Linear Springs are a continuous wave formed (marcelled) wire length produced from spring tempered materials. They act as a load-bearing device with approximately the same load/deflection characteristics as a wave spring. Linear Springs are now available as a standard part in carbon and stainless steel, with over 200 sizes.

Radar automatically monitors rotor blade manufacturing
Identifying defects in fiber composite materials during the production process is now possible thanks to a new and novel radar method developed at the Fraunhofer Institute. The technology automatically and non-destructively monitors the manufacturing process of components such as wind turbine rotor blades.

Image - World's first metalens fisheye camera
World's first metalens fisheye camera
2Pi Optics has begun commercialization of the first fisheye camera based on the company's proprietary metalens technology -- a breakthrough for electronics design engineers and product managers striving to miniaturize the tiny digital cameras used in advanced driver-assistance systems (ADAS), AR/VR, UAVs, robotics, and other industrial applications. This camera can operate at different wavelengths -- from visible, to near IR, to longer IR -- and is claimed to "outperform conventional refractive, wide-FOV optics in all areas: size, weight, performance, and cost."

Image - Closed loop steppers drive new motion control applications
Closed loop steppers drive new motion control applications
According to the motion experts at Performance Motion Devices, when it comes to step motors, the drive technique called closed loop stepper is making everything old new again and driving a burst of interest in the use of two-phase step motors. It's "winning back machine designers who may have relegated step motors to the category of low cost but low performance."

Image - 70% longer service life for linear bushings
70% longer service life for linear bushings
As a result of an optimized production process, Bosch Rexroth's segmental linear bushings with plastic cage used in a wide variety of industries achieve a load capacity that is up to 20% higher and a service life that is up to 70% longer. They are part of a Rexroth round guide with a matching shaft. The increase in load capacity makes it possible to use a smaller size in many cases while meeting the same requirements. Downsizing reduces system costs, saves space, and reduces weight.
