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.

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.
