World’s largest 3D printed boat

Friday 1 Nov 2019

Buoyed by composites technology and the world’s largest 3-D printer, the University of Maine (Orono, ME) launched itself into the record books as it unveiled the largest solid object ever produced by a 3-D printer on 10 October.

The printer produced a 25-foot, 2 ½-ton boat using material that’s a blend of plastic and wood cellulose. A Guinness World Records adjudicator was on hand to certify three records: the world’s largest polymer 3-D printer, largest 3-D printed boat, and largest solid 3-D printed item. The previous record-holder for largest boat created by a 3-D printer was a 4-foot rowboat.

The 3-D boat printed at the University of Maine was created over three days in mid-September. The printer cost US$2.5 million, but the machinery, along with funds for installation, research and development and other costs were covered by the U.S. Army and the U.S. Army Corps of Engineers.

Habib Dagher, the Composites Centre Director and a Professor of Structural Engineering said the State is positioning itself as a leader in developing composites and manufacturing, and using material that takes advantage of the state’s wood products industry makes it even more attractive. As manufacturers look for ways to produce items without plastics and other petroleum-based materials, he said, blends that use renewable resources will be more attractive.
