The world’s first 3D printed kayak. Measures 16ft 8in (5 m) long and cost around $500 to make. Take a look at the video…
The 3D printed kayak by Grassrootsengineering is made of ABS plastic, machine screws, brass threaded inserts and a little bit of silicone caulk.
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 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.
