3D printing at that scale is just too damn slow and prone to failure for serious manufacturing. It's one thing for prototyping, but it's not really viable for at scale manufacturing.
There's a significant cost to making the stamping and casting molds that produce these parts but once they're made, they can produce dozens of units per hour with minimal waste.
Printing a single bumper would take days. And there would be so much waste on support structures, I would guess must of the material cost is waste.
The advantage would be printing rare/hard to find parts, especially for vintage cars.
