Blade tips 3D-printed from advanced lighter thermoplastic composites could help translate into several benefits. Lighter blade tips could allow larger rotors on turbines to generate more power. They would also ease the strain on the entire turbine, reducing wear and tear on gearboxes, drivetrains, bearings and the turbine foundation, thus ...

Windmill Blades - And From What They Are Made

Decades ago if you drove by a field and happened to see a windmill spinning in the wind, chances are the blades were made of wood. With new inventions and better technology today, wood is still used as material for turbine blades. The design is different however. And a lighter wood material is used, in order to carve the blade and faster speed rotation.
