Dr. Nathaniel Petre of Imperial College London isn't the first person to have the idea of 3D printing a surfboard, but the board he created may be the most eco-friendly one 3D printed yet, and it shows a lot of promise for more sustainable - and less expensive - surfboard production in the future. The surfboard was a serious project that received seed funding from NASA, and Dr. Petre worked with colleagues to 3D print the board in sections. Some of the sections were 3D printed from plastic bottles melted down and extruded into filament, and the rest of it was printed with filament from Algix, which creates materials from an invasive diatomic algae.
