If you’re interested in building a kayak but prefer a modern approach, you can take cues from Ivan Miranda, who demonstrated the capability of 3D printing one. Ivan has a massive 3D printer that utilizes a treadmill as its base, making it well-suited for constructing elongated objects like kayaks.
Previously, Ivan attempted a similar project, but it took him a cumbersome seven days to print the kayak. Eager to improve his process, he modified the extruder to increase the printing speed and optimized the design to maximize the printer’s belt width. His enhancements allowed him to extrude over 800 grams of plastic per hour, leading to new challenges tied to the heat generated during printing. Ivan tackled these issues systematically and ultimately managed to create an entire kayak in under 24 hours.
This endeavor is more than just a showcase of 3D printing technology; it also delves into the principles of watercraft design. After printing, Ivan used a sander and a 3D pen to refine the finished product and added foam to certain areas alongside an epoxy coating to ensure it was watertight. However, the kayak posed handling difficulties and was not ideal for ocean use due to its narrow structure. Ivan acknowledged that while it functions as a floating kayak, it requires further modifications for practical use.
Overall, this project highlights the potential for rapidly creating large 3D printed items and emphasizes the importance of maritime engineering principles when crafting functional watercraft.
