Bicycle is created on a computer printer

Daily Mail : Scientists in Bristol, UK, have created the first-ever fully working bicycle by printing it from a computer. The bike is made of nylon, which is as strong as steel and aluminum but weighs 65% less. It was designed on a computer and sent to a printer, which placed layers of melted nylon powder on top of each other to build up the machine. Individual components such as gears, pedals, and wheels are usually made in different factories and assembled into a finished bike, but the Airbike is a single, complete part. The technology is likely to be used in industrial applications such as aerospace, the automobile industry, and engineering.
