You might expect a robot’s heartbeat to be a metallic ticking. But the pulsing in this video isn’t completely artificial: it’s powered by living material, New Scientist reports.
Created by Peter Walters from the University of the West of England in Bristol, UK, and colleagues, the pump uses the gas released by live yeast to generate pressure and distend a membrane, turning it into an… read more

Cornell bioengineers and Weill Cornell Medical College physicians have created an artificial ear that looks and acts like a natural ear, giving new hope to thousands of children born with a congenital deformity called microtia.
They used 3-D printing and injectable gels made of living cells to fashion ears that are practically identical to a human ear.
Over a three-month period, these flexible ears… read more

By caging bacteria in microscopic houses, scientists at The University of Texas at Austin are studying how communities of bacteria, such as those found in the human gut and lungs, interact and develop infections.
In a recent experiment, they demonstrated that a community of Staphylococcus aureus, which can cause some skin infections, became more resistant to antibiotics when it was contained within a larger community of Pseudomonas… read more

NASA’s Marshall Space Flight Center is using ”selective laser melting” (SLM) to create intricate metal parts for America’s Space Launch System (SLS) heavy-lift rocket, saving millions in manufacturing costs.
SLM is similar to 3-D printing (additive printing) and is the future of manufacturing, says Ken Cooper, advanced manufacturing team lead at the Marshall Center.
“This machine takes metal powder and uses a high-energy laser to… read more

A group of researchers in China and the U.S. has created a 3D-printed model of a cancerous tumor to help discover new anti-cancer drugs and better understand how tumors develop, grow, and spread throughout the body.
The model consists of a scaffold of fibrous proteins (gelatin, alginate, and fibrin) corresponding to the extracellular matrix (support structure) of a tumor, in the form of a grid structure 10… read more

NASA and a Texas company are exploring the possibility of printing food on a 3D printer on deep space missions.
NASA has awarded a Small Business Innovation Research (SBIR) Phase I contract to Systems and Materials Research Consultancy of Austin, Texas to conduct a study for the development of a 3D printed food system for long duration space missions.
As NASA ventures farther into space, whether… read more

A new 3D printing process using human stem cells could pave the way to custom replacement organs for patients, eliminating the need for organ donation and immune suppression, and solving the problem of transplant rejection.
The process, developed at Edinburgh-based Heriot-Watt University, in partnership with Roslin Cellab, could also speed up and improve the process of reliable, animal-free drug testing by growing three-dimensional human tissues and structures… read more
A team based at Harvard University and the University of Illinois at Urbana-Champaign has printed precisely interlaced stacks of tiny battery electrodes, each less than the width of a human hair
3D printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have… read more

In another leap for 3D printing, researchers at the USC Viterbi School of Engineering have developed a faster 3D printing process that allows for 3D-printing multi-material objects in minutes instead of hours.
Fabrication time and the complexity of multi-material objects have been a hurdle to widespread use of 3D printing.
Speeding up printing
USC Viterbi researchers developed improved mask-image-projection-based stereolithography (MIP-SL) to drastically… read more

A common vitamin — riboflavin (vitamin B2) — has made it possible to 3D-print non-toxic medical implants, researchers from North Carolina State University, the University of North Carolina at Chapel Hill and Laser Zentrum Hannover have discovered.
“This opens the door to a much wider range of biocompatible implant materials, which can be used to develop customized implant designs using 3-D printing technology,” says Dr.… read more

The new type of material consists of tens of thousands of picoliter connected water droplets encapsulated within lipid films, which can perform some of the functions of the cells inside our bodies.
These printed “droplet networks” might be interfaced with tissues, used as tissue… read more

3M and IBM announced that the two companies plan to jointly develop the first adhesives that can be used to package semiconductors into densely stacked silicon “towers,” making it possible to build, for the first time, commercial microprocessors composed of layers of up to 100 separate chips.
Such stacking would allow for dramatically higher levels of integration for information technology and consumer electronics applications. Processors could… read more
