Additive manufacturing enables us to produce custom surfboards sustainably and on demand, which helps to preserve aquatic ecosystems. Using natural or recycled materials, producing less waste, protecting the health of shapers and sourcing raw materials locally are all levers that enable us to minimize the impact of our boards on the environment. By combining 3D printing of plastic waste and biocomposite lamination, we address two of the major environmental issues of our time: plastic pollution and dependence on oil-derivative products.
