(AP) — The world’s largest 3D printer has created the world’s largest 3D-printed boat. And the University of Maine demonstrated Thursday that it’s seaworthy.

The university unveiled the 25-foot, 5,000-pound boat that was printed at the university’s Advanced Structures & Composite Center. It’s one example of how the massive printer can create larger prototypes to assist companies in product development, said Habib Dagher, founding director of the composites center.

The printer, also unveiled, is currently 70 feet long and will grow to 100 feet with an extension, Dagher said. The university and the Oak Ridge National Laboratory in Tennessee are collaborating on the printer project.

Guinness World Records confirmed it’s the world’s largest 3D-printed boat and the largest 3D-printed object.
