BigRep has tested new Pro Flex filament tire on the streets of Berlin – The World-first 3D Printed Airless Bicycle Tire. The new tire is the latest innovation presenting the world’s first 3D-printed, full-scale airless bicycle tire. BigRep Product Designer Marco Mattia Cristofori explains the use of the flexible properties of the company’s new Pro FLEX filament to bring the tire prototype to life.
Marco Mattia Cristofori, said, “We were able to replace ‘air’ as a necessity in the tire by customizing the pattern to be one of a three-layered honeycomb design. Based on the same principle, the design can be altered to fit the requirements of specific kinds of biking, such as mountain biking and road racing, or for different weather and speed conditions.” Cristofori, added, “Perfecting the design is the trickiest part. Even small changes to the infill percentage or pattern can lead to different results in terms of weight and performance.”
The tire prototype utilizes the full potential of BigRep’s latest filament: Pro FLEX using BigRep ONE large-scale 3D printer. Pro-FLEX is different from other 3D printing filaments due to its unique flexible properties along with high-temperature resistance and durability.
The rigidity and the internal pattern of the tire can be controlled and customized to meet different weather conditions or terrain. A three-layered honeycomb pattern is adapted in the current prototype for urban use.
The airless tires never go flat unlike other average run-of-the-mill tires and are now becoming standard practice in the transportation world.
