The world's lightest 3D print bike rack weighs only 999 grams

Recently, the three British design company jointly created a weight of less than 1kg titanium bicycle frame 3D printing. 3D printing company Mirada Pro, bicycle tube expert Reynolds Technology, and chassis manufacturer Ted James both contributed their knowledge of the frame and reduced their weight using topology optimization software.


Do you think the movement of the material manufacturing began to make you tired of it? Not now, because the three British design pioneers are preparing to launch in recent years, one of the most forward-thinking bicycle components: only 999g of 3D printing titanium alloy frame. Reynolds Technology, also from Birmingham's steel tube business, has been serving bicycle enthusiasts for over 120 years; Ted James, from the Georgia Institute of Metals and Geomatics, Strouder, Lost, is a manufacturer of bicycles and BMX frames. Together, they combine their expertise to create a topology-optimized frame that accelerates the use of 3D printing for bicycles.


From design to manufacture in just eight weeks to complete, this 3D print frame is impressive. It is understood that, despite the British designers did not completely transform the wheels, their cooperation is expected to continue to expand the material for bicycles to make the most important contribution to the stage. The frame features a custom made Titanium 3 / 2.5 tube from Reynolds and a 3D print sleeve fitting designed by Mirada Pro to connect the head tube, bottom bracket, down tube and top / seat tube. The metal parts were welded by James, and such a new frame with torsional rigidity superior to that of conventional alloy frames was born.


The use of topology optimization software is an important factor in the frame weight of less than 1kg. By entering the required load data, Mirada Pro is able to set up CAD software to produce frame parts with less material so that a minimum number of 6/4 titanium alloy 3D print powders can be used to produce a design product of sufficient strength. This reduction in the amount of material not only makes the frame lighter, but also saves the design company money, which means that a molding 3D print frame can be incorporated in the future production.


"The shape is controlled by one of our computer programs," Mirada Pro product engineer Iain McEwan told Cyclist. "We let the frame bear the standard load for safety testing, enter it into the program, and tell it to generate support to support these loads and use the smallest amount of material shape.In other words, if you have a head for the titanium Alloy, you can leave materials that can support the required load while removing the other parts. "


The 3D print frame has not yet become a complete bike, but it has been sent to a stand-alone test lab where it will complete the subsequent test steps. If the results show that the frame is suitable for riding, the three designers may someday will manufacture suitable for large-scale production of 3D printing frame.
