The capabilities of the Metalise™ it... process have proven extremely successful to date in the motorsport industry, most notably in the vital area of aerodynamics. The Formula One teams in particular use rapid prototype models for aerodynamic tests within wind tunnels. The use of Metalise™ it... process on to stereolithography (SL) and selective laser sintered (SLS) prototypes has enabled them to obtain more accurate wind tunnel test data due to a 10-fold increase in stiffness. The coated models closely replicate traditional carbon fiber parts and have eliminated the need for tooling. This has resulted in significant reductions in time spent on creating the parts as well as overall costs.
