The largest 3-D printed object in the world is hitting the river (the Penobscot) this weekend. The University of Maine’s 25-foot 3-D printed patrol boat, 3Dirigo, will be on display at Bucksport’s Town Dock parking lot on Saturday, July 17, from 10 a.m. to 5 p.m. and in Searsport’s Mosman Park on Sunday from noon to 5 p.m.

Both Bucksport and Searsport have many events scheduled this weekend, including live music, food, merchant specials, open houses, displays, a movie, fireworks and more. Visitors can view 3Dirigo up close, free of charge, and speak with representatives of UMaine’s Advanced Structures and Composites Center at both locations.

3Dirigo by the numbers:

The boat has set three Guinness World Records:

1. World’s largest 3D printed boat

2. World’s largest solid 3D printed object

3. World’s largest prototype polymer 3D printer

The boat was printed in 72 hours with a hull form developed by Navatek, a leader in ship design.

The boat is 25 feet long and weighs 5,000 pounds.

The new 3D printer is designed to print objects as long as 100 feet by 22 feet wide by 10 feet high, and can print at 500 pounds per hour.

A $20 million research collaboration with Oak Ridge National Laboratory the U.S. Department of Energy’s largest science and energy laboratory, will support fundamental research in key technical areas in large-scale, biobased additive manufacturing.

The goal is to print with 50% wood products at 500 pounds per hour and achieve properties similar to aluminum.
