World’s First 3D Printed Kayak [STLs Only]

Completely 3D printed Kayak! The Kayak measures 16ft 8in [5.08m] long. All of the 28 Structural Parts are 3D printed, secured together with M5 machine screws & brass threaded inserts and then sealed to each other with a little bit of silicone caulk. That’s it. And it floats. Moves really fast through the water!

The Kayak is comprised of 28, 3D printed sections. Each section has M5 brass threaded thermoplastic inserts so the next corresponding section can be screwed into it with M5x20mm machine screws. Silicone caulk is only used between the sections to ensure it is watertight. This design is heavily modified for 3D printing and requires no supports. To reduce print time and material usage, the kayak can be successfully printed at a 0.65mm layer height, cut you can use any layer height desired. It features a 6mm thick hull with a built-in, internal rib/support structure to give it strength, yet be lightweight and use less plastic. Any print material can be used. On the bow and stern of the Kayak I added attach points for cameras, handles and future add-ons.
