We have already told you, along with the guys from Ocore, about 3D printing applied to the world of boats.
The topic is back in the news after the world’s largest 3D printer created the world’s largest (for now, motor-powered) 3D printed boat in just three days (72 hours). Water tested, it sails like a charm.
Made by the University of Maine at the Advanced Structures & Composite Center on campus, the boat is 7.6 meters long (weighing 2.2 tons). The boat is called 3Dirigo, a play on the Maine motto, “Dirigo,” which is Latin for “I guide. “Roughly speaking, the cost to build it was about $40,000.
The printer, on the other hand, is currently more than 20 meters long and will grow to 30 through an extension: it can “swallow” 226 kilograms of plastic polymer pellets per hour, and in the future, according to university engineers, it can do much better. It cost $2.5 million, provided largely by the U.S. military.
A $20 million research collaboration with Tennessee’s Oak Ridge Laboratory, then, will focus on using bio-based thermoplastics reinforced with cellulose-based materials to create a strong, durable and recyclable 3D printable material. If everything works according to plan, the printer will be able to quickly produce such things as boat molds and fully recyclable accessories.
