3D printers can now make a contribution to ‘green’ technology with a tree, made of 3D printed leaves that contain solar cells. This solar tree, designed by the VTT Technical Research Center of Finland, could be the key to a new concept of renewable energy.

Now, how does it work? The tree stores energy that the leaves harvest from the environment. They use solar energy and kinetic energy, from the wind, to produce usable electricity that is stored in a battery of the tree. This can power your mobile phone, but can also charge other household devices. The researchers used a wood-based bio-material filament to create the tree, a renewable material which makes this a 'green' product.
