the plastic frames and parts - no problem - any fdm machine will easily print those
Probably starting at around £250 and working your way up.

As far as scanning the frames goes - it's a LOT easier to just design the frame from scratch - usually faster too.

Unless you've got £20'000 for an industrial scanner :-)

The metal frame - trickier.
Yes it could be 3d printed in a metal printer. The printers start at £85'000

There are print bureaus who could probably do both.

Once you've designed the part - you can print as many as you like :-)

What sort of money were you thinking of spending ?
