世界首辆由电脑打印的空气自行车(中英文)Bicycle made with computer printer

A bicycle made of nylon is said to be as strong as aluminium and steel - and yet it was made using a printer and computer.

The fully functioning cycle weighs 65 per cent less than a regular bike.

"Scientists in Bristol designed the bike on a computer and sent it to a printer, which placed layers of melted nylon powder on top of each other to build-up the machine," The Daily Mail has reported.

"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 wheels, bearings and axle are incorporated into the 'growing' process, known as Additive Layer Manufacturing."

The Airbike - made by the European Aeronautic Defence and Space group - could be built to the rider's specifications and required no adjustment, conventional maintenance or assembly, The Mail said.

"The 3-D printing method allows products to be made from a fine powder of nylon, carbon-reinforced plastics or metals such as titanium, stainless steel or aluminium," The Mail said.

"They are drawn using computer-aided design and then sent to a printer, which is filled with the powdered material.

"A computer splits the 3-D design into many 2-D layers and a laser beam is used to melt the powder material into the first of the layers.

"This is then covered by a new layer of powder and the process is repeated with the next 'slice'."

The manufacturing process used about one-tenth of the material required in traditional methods, reducing waste.

"The technology is likely to be used in industrial applications such as aerospace, the motor industry and engineering," The Mail said.
