New shape-shfting and color-changing hydrogel could lead to new military camouflage, soft robotics, and flexible displays, researchers report.

See how incredibly tiny micromachines made from metal and plastic move according to their shape. They're a step toward better drug delivery.

New 3D-printable synthetic polymers have morphing powers and can self-heal within seconds. They could be useful for more realistic prosthetics.

"Think of SMILES like a light bulb, but instead of being turned on with electricity, they are turned on with light..."

Researchers have figured out how to measure the viscosity of droplets. That could help control pesticide spraying, ink-jet printing, and more.

"This opens the door to printing soft robotics that could swim like a jellyfish, jump like a cricket, or transport liquids like the heart."

A new kind of bioink shows promise for bioprinting patient-specific bone grafts, or other body parts like ears, blood vessels, or cartilage.

Plastics are a popular 3D printing material, but mechanically weak. New technology overcomes the problem.

A new method lets people create their own interactive 3D-printed objects that respond to touch. They could be perfect for education.

3D-printed stuff can be complex and have lots of hard-to-reach surfaces. But that's no problem for a new method for painting 3D-printed objects.
