It's one thing to 3D print your own kayak, it's another to trust it enough to actually climb in it and float down a river. And the chutzpah meter goes off the charts when it's all done with a 3D printer you completely designed and made yourself at home. That's exactly what Jim Smith did though, and he's calling it "the world's first 3D printed kayak."
At 16 feet 8 inches, the kayak is made of 28 multi-colored pieces held together with machine screws, brass threaded inserts and silicone caulk.
