For surfers, the caudal fins on the surfboard are like soccer shoes. Of course, the impact is not great for newcomers who have just learned to surf, but for surfers, different tail fin designs provide better stability and control, which is essential for improving the performance of surfboards. Recently, in order to help surfers improve their performance, researchers at the University of Wollongong in Australia are developing 3D printed tail fins that can be tailored to the surfers' personal preferences and local spray characteristics.
It is understood that the production of surfboard caudal fins generally involves expensive molds. Therefore, most surfers often only use one kind of tail fin to meet various wind and waves. To this end, the researchers' goal is to change this situation with 3D printing technology , which is to make the tail fins cheaper and easier to manufacture, just as it does in many industries.
So, under the leadership of Professor Marc in het Panuis, researchers at the University of Wollongong have used the 3D printing technology to create several surfboard tail fins, which are currently being tested. In het Panuis is an assistant dean of the Faculty of Science, Medicine and Health at the University of Wollongong and an expert in new materials. The research team tied GPS tracking devices to these surfboard noses to collect data on waves, top speeds, turns and leaps.
The data is then compared to a professional surfer who also surfs with a similar tracking device to help researchers evaluate performance data for 3D printed tail fins. So far, the research team has tracked more than 1,400 waves and 1,100 turns and improved the design on this basis.
“We want to come up with a new, more efficient tail fin that can be tailored to specific surfers and specific waves.†In het Panhuis said: “Most of the current technology is used in the manufacture of caudal fins. Molds, which are expensive to manufacture, are difficult to tailor to the individual needs of surfers. Accordingly, 3D printing technology can quickly prototype and quickly optimize designs for individual needs."
The research team has already negotiated with several Australian surfboard manufacturers, intending to launch the service first in Wollongong and then further promote it. This is also part of the University of Wollongong Global Challenges project.
