could benefit from using metal 3d printers and plastic 3d printers
to produce their own spare parts
in order to repair cars
and it would enable those car repair shops
to have a smaller inventory in their warehouses
so that the car repair shops have more area for repairing cars
and the car repair shops
would not have to wait for deliveries of spare parts
since those spare parts would be 3d printed in car repair shops
so the customers' cars would be repaired faster
which increases probability
that the customers would return for more service in the future
and it would enable those car repair shops
to repair every car there is
no matter how rare spare parts are for any car
since those spare parts would be 3d printed in the car repair shops
which would increase the amount of potential customers
that could use those car repair shops
