Replacing 3D printing plastics with plant-derived materials

Replace 3D printing plastics

A sustainable resin material comprising agriculturally derived components could potentially replace plastics used in large-format 3D printing, which can produce furniture, boats and other similarly sized objects, according to a team of Penn State agricultural and biological engineers.

Penn State researchers use ultrasound to control orientation of small particles

Acoustic waves may be able to control how particles sort themselves. While researchers have been able to separate particles based on their shape — for example, bacteria from other cells — for years, the ability to control their movement has remained a largely unsolved problem, until now. Using ultrasound technology and a nozzle, Penn State researchers have separated, controlled and ejected different particles based on their shape and various properties.  

Mechanical engineering meets electromagnetics to enable future technology

UNIVERSITY PARK, Pa. — Reconfigurable antennas — those that can tune properties like frequency or radiation beams in real time, from afar — are integral to future communication network systems, like 6G. But many current reconfigurable antenna designs can fall short: they malfunction in high or low temperatures, have power limitations or require regular servicing.
