Wheels from a solid block of aluminium consumes about 80 percent of the raw materials.
American manufacturer disks HRE Wheels and GE Additive, specializing in the production of industrial 3D printers, and equipment for additive capacity, introduced the world’s first printed titanium wheels. They consist of five sections, mounted on carbon rims. The dimension of the pilot wheels 20 and 21 inches.
To create discs, called HRE3D+, used two printer production the Swedish company Arcam. They work on the technology of electron beam melting (Electron Beam Melting) – create final detail of a titanium powder, which is melted in a vacuum chamber at the specified in the program template. This solution allows to achieve more efficient use of raw materials, and the resulting parts do not require subsequent heat treatment and strength comparable to forged products.
When you create a wheel from a solid block of aluminium consumes about 80 percent of the raw materials. In the case of electron beam melting that figure is only five percent.
Details of the 3D printer are processed on CNC machines, hand polished and cleaned of excess powder and oils. Assemble the wheels manually: five sections is attached to a carbon rim with titanium bolts. According to engineers HRE Wheels, something like that is impossible to create using traditional manufacturing methods.
Summer German Studio ABT Sportsline has introduced a limited edition series of wheels for the Audi RS5 coupe and wagon RS4 Avant. They are called ABT Aerowheel and aerodynamic flap made of CFRP. The set price was 11 690 euros.
