A 3D Printed Kayak – Believe It Or Not
There’s been much excitement generated in technical circles in recent years by three dimensional (3D) printing. The applications for manufacturing and medical uses are revolutionary. However, as is the case with all technological breakthroughs, eventually the uses for such technology often lean toward a more domestic or recreational slant.
Such is the case with the “world’s first 3D printed kayak”. Made with a “home made” 3D printer by Jim Smith of Grass Roots Engineering, the kayak only cost around $500 to make from reasonably simple materials like ABS plastic, machine screws, brass threaded inserts and a little bit of silicone caulk. The 28 printed sections took over 1000 hours to print in a specially designed heated chamber. They are held together by brass threaded thermoplastic inserts.
The 3D kayak is 16 feet 8 inches long, based on Bryan Hansel’s Siskiwit kayak design. It weighs in at 65 pounds. And … yes … it does float, actually quite well.
