Departing from conventional designs that employ motors and propellers above the water, this inventor chose to equip the vessel with a water propeller for improved performance. The journey to build this groundbreaking boat was not without challenges, including a unique 4D printing process, hours of printing, and numerous experiments to achieve the desired outcome.
The journey commenced with the creation of intricate components through a groundbreaking 4D printing process, which operates at a stunning 7,000 times the speed of conventional 3D printing. Each part, constructed with approximately 600 grams of PLA plastic, demanded a staggering 100 hours of printing time. To expedite the process, multiple printers were utilized. The boat's assembly revealed its sheer magnitude, dwarfing initial expectations. Carbon fiber tubes were artfully integrated onto the sides for structural support.
Selecting a suitable power source presented a significant hurdle. After deliberation, the creator opted for an air propeller system featuring eight compact motors, each boasting an impressive 1.8 kilograms of thrust. The boat's design was streamlined through the implementation of an integrated BEC to power the receiver, simplifying the setup. Despite initial setbacks such as a short circuit, the boat exhibited remarkable resilience, ultimately proving ready for its maiden voyage.
The pinnacle of the project was an exhilarating race pitting the 3D printed RC boat against a gas-powered counterpart crafted by another enthusiast. The race showcased the boat's potential as it tore through the water with breathtaking acceleration and top speeds. Although an unexpected mishap temporarily disrupted the race, swift repairs restored the boat to action, demonstrating its incredible speed and agility.
