Much ado has been made in the last five or so years about 3D printers, from how they are beneficial in technology and medical industries to the controversies about being able to create guns.

Printed items have ranged from tiny to large, some of them for fun and others for more beneficial uses. But wait until you hear about what the University of Maine Advanced Structures and Composites Center turned out at its facility.

The UMASCC team turned out the world's largest 3D printed boat, a 25-footer that weighs 5,000 pounds. It took 72 hours to create.

Pretty cool, eh?

This isn't the only giant thing the UMASCC team has created. They also turned out the world's first floating offshore wind turbine with a concrete hull and a composites tower.

It also created the largest all-composite boat, built for the U.S. Navy Seals. It was 83 feet long, can hit 50 knots, and has sandwich carbon shock-absorbing hull with a 5,000 HP waterjet engine. The team also created the first blast- and ballistic-protection tent in the world, approved by the U.S. military.

Take a look at the video to watch the boat being created.
