The process has been applied for many years with great success in the manufacture of prototypes. Car manufacturers and their suppliers are now increasingly making use of e-Manufacturing in their production process for limited series, custom-made designs and luxury vehicles. The most important arguments in favour are: cost and materials savings, limitless design possibilities, the reduction or even the end of tooling and storage costs, and fast production. Laser-sintering technology also offers Formula 1 (for example Toyota and Williams F1) decisive advantages, because laser-sintered parts are not only quicker, easier and cheaper to produce but can fulfil specific and aerodynamic requirements. One of the visions Formula 1 has for the future is the use of laser-sintering machines right at the racetrack in order to optimize crucial components during races.
