University re-enters race competition

One of the key factors for the University of Hertfordshire team's decision to use the SLS process was the weight saving benefits derived from it.

The University of Hertfordshire will be participating in the Formula Student competition for the tenth year with the development of its UH10 race car.

The team approached 3T RPD for sponsorship and was delighted to build a plenum chamber for their intake system using selective laser sintering (SLS) technology.

One of the key factors for the team's decision to use the SLS process was the weight saving benefits derived from it.

The Nylon material used by 3T in building the part offered high levels of functionality, durability and strength, thereby allowing the wall thicknesses to be reduced.

This minimised the overall weight of the components, thereby improving the car's performance on the race track.

The ability of SLS to create complex forms also meant that the team could make their design as complicated as they liked.

The selective nature of the lasers during the building process and the ability to build parts without structural supports, means that SLS lends itself perfectly to the intricate shapes often demanded by 3T's customers, particularly those in the automotive sector.

This is new technology for the university so it will be carrying out extensive research and pressure testing on the plenum chamber, with a view to establishing whether the material and process is a viable manufacturing option for other areas of the car.

The SLS component will withstand very high vacuums generated by the engine when running, and in 3T's past experience with other Formula Student teams, the Nylon material is more than capable of performing well under these arduous conditions.

The engineering students at the university are well equipped to carry out the necessary testing and research on their race car - a new automotive centre opened there in 2002 giving them extensive engine test facilities, laboratories for dynamics, materials, structures and aerodynamics, composite manufacturing and a new vehicle ride simulation experimental facility.

They also have a moving ground for the wind tunnel and extensive software for modelling all aspects of car and engine performance.

Formula Student is an international competition run by the Institute of Mechanical Engineers (IMechE) that challenges university students from all over the world to design, build, develop, market and compete as a team with a small single seater racing car.

3T RPD supports students every year as it believes this real-life exercise in design and manufacture, together with the business elements of automotive engineering, teaches them valuable lessons and results in the development of highly talented young engineers.

Specialists in the manufacture of rapid prototypes using selective laser sintering (SLS) technology, the parts supplied by 3T give high levels of strength, durability and functionality, enabling the teams to use them in anger in true working environments and as fully operational parts for the duration of their testing and race events.

Driver training and pre-event scrutinising takes place at the Rockingham Festival on 3rd July 2007, with Judging Days and an Endurance Event Day taking place on 12th-15th July 2007 at the Silverstone race circuit.
