Generative design is a relatively new way of looking at lightweighting materials. So as we all know, 3D printing is up and coming. well it is more than up and coming now, It's the it's there, but it's being able to produce things in kind of exotic materials. In the motorsport world, we're looking at 3D printing titanium products like that, which are obviously high value products, but it also allows quick and easy access to a designer to actually start to look at making products as lightweight as possible, but maintaining the strength, rigidity that needs to be able to do the job.
