COLLEGE PARK, Md. The U.S. Army plans to cooperate in artificial intelligence research with teams led by the University of Maryland, College Park and in partnership with the University of Maryland, Baltimore County. The cooperative agreement brings together a collaborative of nearly 30 diverse experts in engineering, robotics, computer science, operations research, modeling and simulation, and cybersecurity.
With the Army s goal of seeking transformational advances in artificial intelligence and autonomy, Army and academic officials said this partnership will accelerate the development and deployment of safe, effective and resilient capabilities and technologies, from wearable devices to unmanned aircraft, that work intelligently and in cooperation with each other and with human actors across multiple environments.

Engineers at the University of Maryland (UMD) have created a morphing nozzle that provides a new way of controlling fibre alignment during 3D printing.

Fibre-filled composites are made up of short fibres that can enhance properties such as part strength or electrical conductivity. The challenge is that these properties are based on the orientations of the short fibres, which has been difficult to control during the 3D printing process.
“When 3D printing with the morphing nozzle, the power lies on their side actuators, which can be inflated like a balloon to change the shape of the nozzle, and in turn, the orientations of the fibres,” said Ryan Sochol, an assistant professor in mechanical engineering and director of the Bioinspired Advanced Manufacturing (BAM) Laborato

Engineers at the University of Maryland (UMD) have created a new shape-changing or morphing 3D printing nozzle that was featured as a Frontispiece in the January 5th issue of the journal
Advanced Materials Technologies.
The team s morphing nozzle offers researchers new means for 3D printing fiber-filled composites - materials made up of short fibers that boost special properties over traditional 3D-printed parts, such as enhancing part strength or electrical conductivity. The challenge is that these properties are based on the directions or orientations of the short fibers, which has been difficult to control during the 3D printing process, until now.
