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.

Flock Theatre will be showing Samuel Beckett’s one-man drama Krapp’s Last Tape live online for four nights, Jan. 14-17.
On a “late evening in the future,” Krapp, played by Christie Max Williams, begins his yearly birthday ritual of recording an audio diary of the previous 12 months on his reel-to-reel tape recorder. Before making his recording, however, the 69-year-old Krapp digs out and reviews a tape recorded by a 39-year-old Krapp. The elder Krapp listens, laments, pauses and rewinds portions of the tape, occasionally chuckling along with the younger Krapp s musings on another even younger 29-year old iteration of Krapp. The audience is welcomed into Krapp’s mind as he reviews and responds to the worries and aspirations of his younger selves, and we watch in real time as he realizes what became of those dreams he once had.
