SLA technology helps Jaguar Racing to develop a head-and-neck support (HANS) system not only in record time, but also tailored to the individual requirements of each of its Formula 1 drivers Head-and-neck support systems are now a compulsory safety feature for the 2003 Formula 1 season. While off-the-shelf yoke and collar systems already exist, drivers criticise them for being uncomfortable. A good enough reason for the Jaguar Racing design team to apply a bit more science and engineering to the problem. Solid imaging technology from 3D Systems allowed the team to produce accurate models directly from CAD data captured from individual driver positions and torso dimensions, thus aiding the development of a HANS system that was more sympathetic to drivers' individual builds. Another advantage of using this technology is speed; prototype collars were produced by the team in a single weekend. Jaguar Racing managing director, Dave Pitchforth, takes up the story: Using 3D Systems SLA machines we were able to manufacture numerous prototype models within the 48 hours available, allowing us to test many different design iterations for optimum driver comfort. The complicated amorphous shape of the HANS, moreover, would have required the use of expensive tooling had we used traditional modelling techniques - and time that we simply didn't have.
