Pictured above: Part of the super lightweight, aerodynamic stem and handlebars made for Sir Bradley Wiggins.

Material: Titanium Alloy (Ti-6Al- 4V)

Process: Electron Beam Melting (EBM)

Idealised metal foam
Idealised metal foam
Pictured above: A lattice structure. Lattice structures are attractive for a number of applications, such as providing impact protection, reducing weight in automotive and aerospace components, or providing insulation from heat and sound. Additive manufacturing offers unprecedented control in the design and manufacture of these structures.

Proof of concept nose cone
Nose cone
Pictured above: Proof of concept nose cone for the ultimate jet and rocket powered car BLOODHOUND. Our nose cone paved the way for the manufacture of the final part by a UK company by showing what could be done.

Material: Titanium Alloy (Ti-6Al- 4V)

Process: Electron Beam Melting (EBM)

Partners: The BLOODHOUND Project

Acetabular cup
Acetabular Cup, used in hip surgery.
Pictured above: Acetabular Cup, used in hip surgery. Additive manufacturing can be used to design specific features and textures into devices. The surface structure of this hip implant has been designed and manufactured to encourage bone growth into the surface of the implant and better bonding of the implant to the patient’s hip

{image5}Pictured above:  Idealised metal foam. It was reverse engineered from a scan of a randomly packed jar of marbles. Additive manufacturing allows researchers to make foams with the same structure, but different densities, to better understand their properties and improve the design of new foams for uses including providing impact protection in the automotive sector.
