MIT Lab’s Toroidal Propellers Make Drones Much Quieter
A team at MIT’s Lincoln Lab have designed a new shape of quadcopter propeller which drastically reduces the noise generated from the drones.
In figuring out why it works so well, they realized that the vortices generated by the design are distributed across the whole of the propeller instead of just the tips, making it dissipate faster in the atmosphere.

Monitoring Progression Of Movement Disorders W/ Soft Sensors
A multi-disciplinary team of researchers has developed a way to monitor the progression of degenerative movement disorders such as Duchenne muscular dystrophy (DMD) and Friedreich’s ataxia (FA) using wearable motion capture technology and AI.
Tracking the progression of these diseases is normally done through intensive testing in a clinical setting. This research offers a more precise assessment that increases the accuracy and objectivity of the data, and should allow for a quicker and more efficient path to developing new drugs compared to current methods.

New Carbon Nanotube Yarn Harvests Mechanical Energy
UT Dallas researchers have made novel carbon nanotube yarns that convert mechanical movement into electricity more effectively than other material-based energy harvesters. Their new version is constructed much like traditional wool or cotton yarns and could be incorporated into clothing to harvest human motion.
Researcher Dr. Ray Baughman, “Our materials do something very unusual. When you stretch them, instead of becoming less dense, they become more dense. This densification pushes the carbon nanotubes closer together and contributes to their energy-harvesting ability.”

Researchers Explore Harvesting Energy From Moving Trains
“Virginia Tech researchers have created a new type of railroad tie that generates electricity as a train’s wheels roll over it, providing power in remote locations to operate rail systems.”
“Their high-tech tie, placed underneath the rail, is topped with a heavy metal bar mounted on a spring. As the wheels of the train pass over the rail, the train’s weight pushes down on that bar, triggering a series of gears. Those gears rotate a generator, creating electricity, which can then be stored in a battery.”

A Lot Happened In The World Of 3D Printing Last Year
Here’s a nice roundup of all the happenings in additive manufacturing in 2022. Tons of news processes, materials and applications for 3D printing, and I think it is only going to continue growing.
Multi-Material Digital Light Processing 3D Printing
A joint team of researchers from Japan and Singapore have developed a new technique for creating high resolution (40µm) hybrid plastic/metal parts. It’s called multi-material digital light processing 3D printing (MM-DLP3DP).
Similar to standard resin 3D printing, this process adds a few extra steps. Firstly the printer uses both resin and a pre-cursor material. Once printed, the parts are further processed in a plating bath, and the pre-cursor material is plated, while the standard resin is not. This allows for intricate and nested plated metals and could potentially be used as a way to create 3D circuits.

Centrifugal Manufacturing Allows For Multi-Resin 3D Printing
Chinese researchers have figured out a way to enable multimaterial resin 3D printing, overcoming the problem of mixing incompatible resins.
They created a process called ‘Centrifugal Manufacturing’ which is similar to regular resin UV printing, but between layers, the build plate is removed from the tank and spins extremely fast, removing all wet resin.
The system can then automatically continue the print in different resin tanks, enabling multi-colour and multi-material resin prints.
