With a groundbreaking new technology, British scientists have "printed" bicycles for the first time. They first use a computer to design and then use a printer to print. This fully-featured bike, called "Airbike", is made of nylon material, which is the result of an eye-catching project. Its firmness is comparable to that of aluminous materials, but its weight is reduced by 65%.
Scientists in Bristol, United Kingdom, designed this bike on a computer and then used a printer to print it. The printing process is the accumulation of layered nylon powder, and finally "heap" a bicycle. Typically, bicycle parts such as transmissions, pedals, and wheels are manufactured by multiple factories and then assembled into bicycles. In contrast, Airbike uses an integral structure. Wheels, bearings and axles are manufactured during the printing process. The printing process is called "add layer manufacturing."
Airbike can print according to the consumer's requirements without adjustment. In addition, this bicycle does not need to be repaired or assembled. Airbike manufactures at the European Aerospace Defense Company (EADS) in Felton near Bristol. This 3D printing method makes it possible to use thin nylon, carbon-reinforced plastic, or metal powders such as titanium, stainless steel, and aluminum.
Scientists used computer-aided design software to design Airbike, which was then printed using a printer containing powdered raw materials. The computer software divides the 3D design image into many 2D layers, and uses a laser beam to melt the powdered raw materials to print layer by layer. As one layer is covered by another layer, a bicycle finally comes out.
In this way, only one-tenth of the raw materials used in traditional manufacturing methods are used, which greatly reduces waste. In addition to bicycles, this technology can also be applied in aerospace, engine manufacturing and engineering. Chief engineer Andy Hawkins said: “Additional layer manufacturing has a very broad application prospect and is a technology that can change the rules of the game. The advantage of this technology is that complex designs can be realized at very low cost. Can shape any shape you want. Airbike uses a lot of unique designs, such as cushioned seats and axle bearings."
Robin Soswell, CEO of European Aerospace Defense Group UK, said: “Airbike is a imaginative example of innovation in the UK. The EADS Bristol team is made up of some world-class engineers who stand The forefront of technology, through unremitting efforts to promote technology boundaries."
