Scientists at the University of Washington have re-created the distinctive spiral shapes of shark intestines in 3D-printed pipes in order to study the unique fluid flow inside the spirals.

They 3D-printed prototypes using the softest polymer available. The flexible pipe designs performed at least seven times better than all previously measured Tesla valves.

Flaps perform essential jobs. From pumping hearts to revving engines, flaps help fluid flow in one direction. Without them, ...

JuggerBot 3D and ORNL launch second R&D collaboration - building on the production-ready technologies developed previously.

As with any desktop 3D printer, the Vulcan printer pipes layer by layer to build an object – except this printer is more than 45 feet (13.7 m) wide, weighs 4.75 tons and prints residential homes.
