RIETI, Italy, Sept. 26 (UPI) -- The world's largest 3-D printer is capable of building clay dwellings aimed to be used to supplement a growing global housing crisis.
Italian collective WASP -- or World's Advanced Saving Project -- presented their 40 foot high, lightweight printer named Big Delta last week during a three-day festival celebrating the feat. Unlike other large scale 3-D printers focused on building structures, this device is capable of creating an entire hut from the bottom up during one printing session. Its principal building material is mud.
