University of Washington Students 3D Print Out Boat, Place Second In Race

It's not much to look at, but it is possibly the first 3D printed boat, helmed by Matt Rogge of the University of Washington' Washington Open Object Fabricators club. It's interesting for a number of reasons; 1) it actually floats and came in second in a race;

2) It's made from recycled milk bottles. Faculty advisor Mark Ganter notes that this isn't easy.

"Frankly, milk jug material is an awful material to work with," he said. "It shrinks, it curls, it doesn't want to stick to itself. Overcoming all those parts of the problem was part of the achievement."

From the WOOF team:

WOOF group has spent the last two months researching. engineering, extruding, printing, and dumpster diving for the greater good. WOOF submitted the first 3D printed milk jug boat into the Seafair Milk Carton Derby. Not a simple task, they hacked a 4′ x8′ plasma cutter, slapped a homemade extruder on, and dealt with 2% shrinkage, to produce a beautiful boat. The boat weight is 40 lbs (~250 1 gallon Milk jugs) supports 150lbs, yet cuts through the water like a canoeyak.

Closup of the boat. You can tell that this was not easy to work with.

Impressive. More at the University of Washington and Inhabitat

What they really need next year is a better printer. Dutch designer Dirk Vander Kooij recycles old fridges and extrudes the ribbon with a robotic arm, and gets much finer detail. More here.
