The University of Maine Advanced Structures and Composites Center recently used its 3D printer to construct the world’s largest 3D-printed boat. In doing so, the university was awarded three Guinness World Records for the world’s largest prototype polymer 3D printer, largest solid 3D-printed object, and largest 3D-printed boat. The boat, named 3Dirigo, is 25′ long and weighs 5,000-pounds. 3Dirigo is built of a 50% plastic-wood cellulose blend and took 72 hours to print. The U of Maine 3D printer can print objects up 100′ long.

Below are two videos — the first of the 3Dirigo’s unveiling and the second a timelapse video of the boat being printed.
