Maine Team Sets Three Guinness Records with 3D-Printed Vessel
ORONO, Maine — The University of Maine has secured three Guinness World Records with a single 3D-printed boat, a 25-foot vessel that emerged from the world's largest prototype polymer 3D printer in just three days. The craft, named 3Dirigo, weighs 5,000 pounds and was unveiled Thursday at the school's Advanced Structures and Composites Center, with Guinness officials present to certify the achievements.
The records include the largest 3D-printed boat, the largest solid 3D-printed object, and the largest prototype polymer 3D printer. A time-lapse video released by the university shows the entire construction process compressed into about 30 seconds, offering a glimpse of the printer's capability to produce large-scale items rapidly.
Following the ceremony, researchers tested the vessel's seaworthiness in the Alfond W2 Ocean Engineering Laboratory, a facility equipped with a multidirectional wave basin and a high-performance wind machine. The successful test demonstrated that the boat is not just a static display but a functional watercraft.
Printer's Capacity Extends Beyond the Boat
According to a university press release, the 3Dirigo is not the maximum output of the printer. The machine can theoretically produce objects up to 100 feet long, 22 feet wide, and 10 feet high, suggesting potential for even larger projects in the future.
The university has already identified practical applications for the technology. A partnership with the U.S. Army aims to develop shelter systems for soldiers that could be rapidly deployed in the field, highlighting the printer's potential for on-demand manufacturing in military contexts.
The achievement underscores the growing role of large-format additive manufacturing in sectors ranging from marine construction to defense. While the boat is a demonstration of scale, the underlying technology could reshape how structures are built, offering speed and customization that traditional methods may not match.
As the university continues to explore the printer's limits, the records set by 3Dirigo may be a stepping stone to even more ambitious projects, with the Army collaboration already in the pipeline.
