Team members from the Washington Open Object Fabricators (WOOF) group with their 3D-printed boat last year.

Just last month we reported on University of Washington engineering students building bad-ass, award-winning Formula race cars. Now the latest creation from the UW campus is a 3D-printed boat made entirely out of plastic milk jugs.

woof3dprinting1Last year, a group called Washington Open Object Fabricators (WOOF) printed the world’s first recycled high-density polyethylene boat, and now they are doing it again for the Seafair Milk Carton Derby this Saturday at Seattle’s Green Lake Park.

The students went out to the dumpsters last year and collected as many milk jugs as they could, cleaned them, broke the material down and then printed the boat in layers. The 40-pound boat actually finished in second place in its heat at last year’s derby, which requires all racing boats to be made of milk cartons or jugs.

The WOOF team detailed their printing experience last year in multiple blog posts. Check out their impressive work here, and head over to the blog to learn more about WOOF.
