3D-printed skin closes wounds and contains hair follicle precursors

3D printing in Penn State Lab

Fat tissue holds the key to 3D printing layered living skin and potentially hair follicles, according to researchers who recently harnessed fat cells and supporting structures from clinically procured human tissue to precisely correct injuries in rats. The advancement could have implications for reconstructive facial surgery and even hair growth treatments for humans.

3D printing affordable, sustainable and resilient housing in Alaska

Alaska needs an estimated 27,500 new housing units over the next 10 years to alleviate overcrowding and unsanitary conditions, according to the Alaska Housing Foundation Corporation. An interdisciplinary team of Penn State researchers led by José Pinto Duarte, Stuckeman Chair in Design Innovation and director of the Stuckeman Center for Design Computing (SCDC) in the College of Arts and Architecture’s Stuckeman School, is looking to alleviate some of that stress with a $376,000 U.S. Department of Housing and Urban Development (HUD) grant.

Replacing 3D printing plastics with plant-derived materials

USDA grant to fund Penn State researchers developing new and sustainable materials from lignocellulosic biomass


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.
