I have completed construction of a completely 3D printed, customized Kayak. The Kayak measures 16ft 8in [5.08m] long and cost around $500 to make. It is made of ABS plastic, machine screws, brass threaded inserts and a little bit of silicone caulk. That’s it. And it floats. And I can Kayak around in it. In order to print such large, solid sections of Kayak, I had to modify my home-built, large scale 3D printer to print the parts inside a heated chamber so they would not warp or crack.

The Kayak

The Kayak is comprised of 28, 3D printed sections. Each section has brass threaded thermoplastic inserts so the next corresponding section can be screwed into it. Silicone caulk is only used between the sections to ensure it is watertight. This design was initially based on the Siskiwit Bay kayak by Bryan Hansel, but heavily modified for 3D printing. The shape of the kayak was tweaked to optimize performance based on my height and weight. To reduce print time and material usage, the kayak is printed at a 0.65mm layer height. It features a 6mm thick hull with a built-in, internal rib/support structure to give it strength, yet be lightweight and use less ABS plastic. On the bow and stern of the Kayak I added attach points for cameras, handles and future add-ons.
