Embedded "biofactories" in hydrogel could give people in remote places a portable way to produce hard-to-get medicines.

A "bio-ink" for 3D-printed materials could serve as scaffolds for growing human tissues to repair or replace damaged ones in the body, say bioengineers.

Bioengineers are using grooves to seed sophisticated, 3D-printed tissue-engineering scaffolds with living cells to help heal injuries.

Tiny 4D-printed microneedles that mimic parasites and porcupines could one day mean the end of painful hypodermic needles.

3D-printing has created two tiny versions of Michelangelo's "David," one 1 mm tall, and the other just one-tenth the size of that.

"DNA is currently the only data storage medium that can also exist as a liquid, which allows us to insert it into objects of any shape."

The structure of bones can help 3D printed materials stand up to more wear and tear, which could lead to stronger materials for buildings and vehicles.

A new method for 3D printing glass creates complicated objects without any of the hassle of previous techniques, researchers report.

3D printing high-performance electronic circuits right into plastic could pave the way better drones, medical implants, and more.

A new 3D-printed device can filter out red blood cells to leave undamaged cancer cells which could help diagnose disease or improve personalized treatments.
