Urwahn Bikes presents an urban bicycle frame made of titanium using 3D printing
The German company Urwahn Bikes has unveiled an innovative variant for the structure of its urban bicycle model Softride. This update employs titanium processed with additive manufacturing, specifically using electron beam fusion technology. This advance allows the main frame part to be generated in a single complex piece, eliminating conventional welding processes. The goal is to perfect the shape and structural characteristics of the assembly. 🚲
Integration of the Softride system into the new design
The frame retains the Softride rear suspension system, which distinguishes the brand. This mechanism works with a carbon fiber swingarm that flexes to mitigate pavement vibrations. The new titanium structure couples with this component to achieve a pedaling experience that aims to harmonize efficiency with a level of comfort. The geometry is configured for primarily urban and recreational use.
Key features of the frame:- Main structure manufactured as a single piece using 3D printing with titanium.
- Maintains the carbon swingarm of the Softride system to absorb impacts.
- Geometry oriented to provide a comfortable ride for the city.
Additive manufacturing redefines how we build bicycles, enabling shapes that were previously impossible.
The additive manufacturing process step by step
Urwahn produces this frame in cooperation with Additive Industries. For this, they use the MetalFAB1 platform to handle grade 5 titanium powder. The electron beam fusion technology under vacuum consolidates the material layer by layer. This enables the creation of organic contours and internal designs that could not be achieved with traditional machining or casting techniques. After printing, the frame only needs manual surface polishing.
Production method details:- Collaboration with the specialized company Additive Industries.
- Use of the MetalFAB1 machine and grade 5 titanium powder.
- The technique operates in vacuum and melts the material with an electron beam.
Considerations on the design and its application
Although it promises long durability and a distinctive appearance, some users might question whether the performance justifies the high inherent cost of a single-piece 3D-printed titanium frame, especially for everyday commutes in urban environments. The innovation lies both in the manufacturing method and in the integration with established suspension systems. 🛠️
