What can make life better man? Certainly a clean, right? What can get better man? Certainly an air rich in oxygen and clean, right? What can arricchiere the air we breathe? Certainly the plants that release oxygen into the atmosphere, right? I believe that with these, "my" three certainties, 3D printers possiano help improve the life of man. 1 - Recycling plastic and transformation = ambient + clean. 2 - Replication of particular, where possible, up to now made in wood. 3 - Less cut trees = + release of oxygen in the air. From this I thought of making a model of chair, a bit revisited, but already seen on the web, to improve the lives of mankind. Of course this is a small personal example.
