FRESH 3D-Printing Platform Paves Way for Tissues, Organs

Research into 3D bioprinting has grown rapidly in recent years as scientists seek to re-create the structure and function of complex biological systems from human tissues to entire organs. In APL Bioengineering, researchers from Carnegie Mellon University provide perspective on the Freefrom Reversible Embedding of Suspended Hydrogels 3D bioprinting approach, which solves the issue of gravity and distortion by printing within a yield-stress support bath that holds the bioinks in place until they are cured.

3D-Printed Smart Gel Changes Shape When Exposed to Light

Inspired by the color-changing skin of cuttlefish, octopuses and squids, Rutgers engineers have created a 3D-printed smart gel that changes shape when exposed to light, becomes “artificial muscle” and may lead to new military camouflage, soft robotics and flexible displays. The engineers also developed a 3D-printed stretchy material that can reveal colors when light changes, according to their study in the journal ACS Applied Materials & Interfaces.

UCI materials scientists discover design secrets of nearly indestructible insect

Irvine, Calif., Oct. 21, 2020 – With one of the more awe-inspiring names in the animal kingdom, the diabolical ironclad beetle is one formidable insect. Birds, lizards and rodents frequently try to make a meal of it but seldom succeed. Run over it with a car, and the critter lives on. The beetle’s survival depends on two key factors: its ability to convincingly play dead and an exoskeleton that’s one of the toughest, most crush-resistant structures known to exist in the biological world.
