Harvard engineers created rotational multimaterial 3D printing that embeds air channels in soft robotic parts, enabling hand-like motion without molds.

The researchers turned to hydrogels, which are water-rich, jelly-like polymers that respond to temperature and chemicals. But ...

I love creating things on my 3D printer, but I’ve always hit a wall because I’m not an engineer and traditional 3D design software can be really tricky. In ...
