Yuyo, the first eco-designed & 3D printed surfboards As a surfer, the ocean is our playground. If we want our children and future generations to be able to continue to surf, we must respect and protect this natural environment. However, despite too few local initiatives, the surfboards we use are still too polluting, non-recyclable and toxic for the marine environment. This is the surfer's paradox. Today, thanks to 3D printing, we are able to manufacture boards whose core is made up of plastic waste. We then laminate this core with a biocomposite alloy, to obtain surfboards that help to preserve ecosystems.
