This option uses an additive manufacturing technique (3D printing) to process smaller components in high performance polymers. No tooling is required for this production route, but 3D CAD data is needed. Again, as per options 1 and 2, reverse engineering by scanning and CAD modelling is how this would be achieved. If the components require a smooth A-surface finish, ready for painting, then this route may not be suitable. This route is only really suited for smaller components (such as clips and caps) due to the build platform on the 3D printing machines.
