The modelling is not that hard for the arch trim as its essentially a
single rail sweep, the profile of the arch and the trim is not difficult.
3d scanners are available.. but not needed for a job like this. you model
the sectional profile of the trim and sweep it along the path of the wheel
arch lip.
I have 3d printed quite a few things lately.. but you need to use a powder
printer for fine detail and smooth surface.
There is a firm in the EU printing repro aston martin parts!
