Boat created with a custom-built printer and built to fit the owner’s height and weight.
Jim Smith, the engineer behind the website Grass Roots Engineering, has created a perfectly usable 3D-printed kayak.
The kayak measures around 17 feet long, weighs about 65 pounds, and cost $500 to make. Smith used ABS plastic, machine screws, brass threaded inserts, and silicone caulk to create the whole thing.
Smith built the kayak with his home-built large scale 3D printer, which he had to slightly modify to print all 28 kayak parts inside a heated chamber that prevented them from cracking or warping.
Smith used the design of the Siskiwit Bay kayak by Bryan Hansel and modified it for 3D printing. He also customized the shape to fit his height and weight, and added points for cameras, handles and other add-ons on the bow and stern.
The project shows how 3D printing technology can enable enthusiasts to customize their kayaks to their own height, weight, and other preferences.
