 | AI software checks 3D-printing quality in real time
Oak Ridge National Lab researchers have developed artificial intelligence software for powder bed 3D printers that assesses the quality of parts in real time, without the need for expensive characterization equipment. Their method for identifying surface-visible defects can work on multiple printer models -- and possibly could be used to fix problems as they happen.

 | Eliminating latency in next-gen WiFi 6E devices
With WiFi 6 promising a reduction in latency of approximately 75%, many product developers are understandably excited. But overcoming traditional latency problems could still be a challenge, given the proximity of the original WiFi 6 frequencies to other active bands of the spectrum. How can these issues be resolved? Johanson Technology takes a look.

 | Brushless DC motor with integrated driver saves space and time
Portescap's newest addition to their Ultra EC mini brushless DC motor platform is the 16 ECP motor with integrated driver. These 16-mm diameter motors are available in two lengths (36 and 52 mm) and offer almost 50% more continuous torque over comparable motors, without compromising on smooth operation and long life. The integrated driver reduces many of the complexities associated with motor operation, cuts down installation time, lowers overall footprint, minimizes wiring, and offers cost-optimization benefits. These motors are a good fit for respiratory and ventilation devices, miniature pumps, medical hand tools, clinical diagnostics, and valve actuation, as well as many other applications.

 | IKO expands line of CFKR cam followers
IKO International has expanded its line of CFKR series of Double Hex Hole Cam Followers. The outside diameter of the outer ring is now available in 22 and 26 mm, with current models as high as 90 mm. These bearings are designed for outer-ring rotation and have superior rotational performance with a small coefficient of friction and high load capacity. Consider the CFKR 90 model, which features a dynamic load rating in excess of 45,000 N, compared to 40,500 N for similar cam followers on the market. Because the structure of the CFKR series features hexagon holes on both stud ends, it can be tightened from the roller or stud end. Other variations available.

 | Powder and e-coat-compatible seam sealant provides toughness and flexibility
Designed to prohibit liquids, solids, and gases from entering through gaps and voids in metal seams, Henkel's new Loctite EA 3501 HT is a one-part, heat-cure epoxy seam sealant that offers excellent adhesion to primed or bare oily metals. This grey sealant maintains its flexibility, adhesion, and color after exposure to paint bake processes up to 225 C, and is ideal for use on a range of outdoor power and heavy-equipment vehicles including agricultural, construction, utility, marine, and sports/leisure, as well as work trucks and trailers. This epoxy provides a tough, flexible bond on metal seams between welded or bonded joints, butt joints, and other visible seams to prevent rust and corrosion.

World's first manned aerobatic drone does stunts
Drone Champions AG, creators of the Drone Champions League, has unveiled the first-ever manned drone capable of aerobatic maneuvers such as rolls and loops. Yup, you read that right -- someone can sit inside this thing while it's flown by a pilot on the ground. The "Big Drone" is the brainchild of Drone Champions founder Herbert Weirather, who personally assisted in the testing process by sitting in the single-seat machine during some of the testing (although a dummy was probably used for the really wild stunts) as it was piloted on the ground via RC controller. Nutty.
