According to the British Daily Mail, it looks like a modern art sculpture, but in fact it is a bicycle frame made by a 3D printer. Currently, two companies in the UK have built the first 3D printed metal bicycle frame based on this innovative bicycle frame design.
Made of titanium alloy material, the bicycle frame achieves the lightest quality and the highest hardness, but its parts still need to be assembled manually. This project was designed by Renishaw (the only manufacturer of 3D printing using metal parts in the UK) and bicycle design company Imperial Bicycle Company. It is based on the MX-6 mountain bike of the Imperial Bicycle Company. Tensile strength above 900 MPa (Mpa).
The bicycle frame has the characteristics of hollow high strength, which is one third lighter than the original material. It adopts the "topology optimization" design, which means that the software is used to allocate the material structure in the most intelligent way. Renishaw pointed out that the material is removed from the low-stress area to achieve the optimal design of the load bearing, thereby eliminating some unnecessary materials and making the bicycle lighter.
The bicycle frame is connected to a metal plate after printing and manufacturing, and can be combined together when it is damaged. Renishaw pointed out that it uses an improved elastic design, this process means that the bicycle frame can be tailored to the precise needs of the individual.
At present, this 3D bicycle has not been sold, and researchers at the University of Swansea in the UK are using strain gauges to measure their performance in the laboratory and in the mountains.
Although the metal bicycle frame is still in its infancy, bicycle enthusiasts in the future can easily print bicycle frames and other parts and order customized 3D printed bicycles.
